Hydril GX™ 10,000 psi Annular Blowout Preventer
Hydril's complete line of annular blowout preventers is based on more than 55 years of application experience in all BOP types, sizes, and pressure ranges. There is a Hydril Annular BOP to meet most operational requirements in the petroleum industry today, both on the surface and subsea. Hydril designs are durable for dependable and efficient operation. A standard annular BOP will strip drill pipe and tool joints. The packing unit life is reduced when used for stripping operations. It will also close off the annulus or open hole to full working pressure. The Hydril Annular BOP provides quick, positive closing action with simplified controls to keep drilling fluids in the hole when a blowout threatens. The universal seal off feature of the annular blowout preventer permits closure and seal off on drill pipe, kelly, tool joints, or tubing and wireline as well as the open hole. Maintenance of the BOP is easy, rapid, and economical with the use of standard tools. The Low Alloy Steel Pressure Vessel represents Hydril's 50 years of experience in producing BOPs to provide optimum strength and stress distribution control. Full-spectrum testing meeting or exceeding API requirements ensures that the desired safety factors and reliability are provided in each unit.
Finite Element Analysis of the body design is the most advanced, in-depth technique of pressure vessel design analysis and ensures a structurally sound body configuration. Shell (Hydrostatic) Testing of the BOP body meets the API accepted industry standards to provide a safe, reliable blowout preventer. API 16A is the latest API specification covering drill through equipment. Hydril is licensed to manufacture Blowout Preventers to these exacting standards. In addition, Hydril preventers may also be certified by such certifying authorities as Det Norske Veritas (DNV), American Bureau or Shipping (ABS), or Lloyds of London. Operating Chambers are Pressure Tested to rated working pressure of the BOP or 3000 psi, whichever is greater. This ensures strength, reliability, safety, and the ability to over-pressure the chambers in well-control situations. Stainless Steel and Inconel-lined Ring Grooves are available as options.

THE GX . . . THE FIELD PROVEN FLAGSHIP PREVENTER OF HYDRIL'S FLEET The GX offers extra performance and serviceability while retaining the field proven features of Hydril annular BOPs. The GX delivers extended operating service with few packing unit changes, with a design that is simple and easy to maintain in both surface and subsea operations. The GX will close on virtually any drill stem member or seal off the open bore. Operating volumes are lower, resulting in faster closing times and smaller accumulator requirements. Packing Unit fatigue and stripping life have been increased beyond previous industry levels for equivalent sized Annular BOPs. The GX allows full control of packoff tightness during stripping operations, regardless of wellbore pressures. The structural design, quality and testing of the GX continues Hydril's state-of-the-art advances. Here are the field proven Hydril features the GX provides:
■
Long piston design for optimum stability and reliable operation..
■
Latched Head for fast and easy access to packing unit and seals..
■
Opening Chamber Head to prevent inadvertent contamination of the hydraulic system during packing unit replacement.
■
Four large pressure energized lip seals are used for dynamically sealing piston chambers.
■
Replaceable Wear Plate eliminates metal to metal contact between the packing unit inserts and the BOP head,making field repair fast and economical.
■

STRIPPING The design of the GX effectively controls positioning of the inserts. When stripping, the inserts remain fixed as the rubber flows in and out, allowing the alternating diameters of pipe and tool joints to pass through the closed packing unit. This results in a dramatic increase of the GX packing unit stripping life – to approximately twice that of similar sized annular BOPs.

HYDRIL
BALANCED PISTON Piston stability is assured by Hydril's time proven long piston design with contact points providing a length-to-diameter ratio approaching 1. This design eliminates any tendency to cock and bind during operations with off-center pipe or unevenly distributed accumulations of sand or cuttings. The GX piston is completely balanced. The opening and closing chamber areas are of equal size. This equalizes the hydrostatic forces exerted on the piston by the control fluid column in subsea operations. The result is a BOP that utilizes a constant closing pressure regardless of water depth or mud weight. This piston design is such that the closing pressure requirements are virtually independent of well bore pressures. Contoured angular tapers on the piston bowl compress and displace the reservoir of feedable rubber in the back of the packing unit. This design assures optimum rubber feeding and closing efficiency. Movement of the piston to the open position allows the packing unit to relax to full open bore.
EXTRA PACKING UNIT LIFE The heart of any annular BOP is its packing unit – and the GX is no exception. Its packing unit has a greatly increased reservoir of high-quality feedable rubber. Because the reservoir of feedable rubber is larger, the GX permits continuous rubber feeding as the boresurface wears. The packing units reinforcing flanged steel inserts are driven by the rubber during closure and quickly reach a fixed position where they form a steel ring to support the rubber from upward motion under wellbore pressure. Once the inserts reach their fixed position, rubber continues to flow inward, effecting a positive seal off on the drill string or the open bore. The rubber is primarily in compression and is therefore resistant to tears, cuts and abrasions. The steel inserts stabilize the rubber and control the flow pattern to minimize rubber stress. Packing unit life due to routine testing at full working pressure has been increased beyond previous levels. Because Hydril Company manufactures all its own packing units, rigid quality control is assured and field performance enhanced.
MORE PRECISE CONTROL Tool joints can be stripped through the closed packing unit while a full seal is maintained on the pipe. The GX packing unit design permits precise control of packoff tightness, regardless of wellbore pressures. This allows a slight drilling fluid leakage to be achieved during stripping operations to provide lubrication, optimize pull through forces and prolong packing unit life. The result is the ability to strip long strings of pipe and tool joints in or out of the hole at higher wellbore pressures.

Cylinder Bore (in.) MPL The GK Annular Blowout Preventer was designed especially for surface installations and is also used on offshore platforms and subsea. The GK is a universal annular blowout preventer with a long record of proven, quality performance. Only Two Moving Parts (piston and packing unit) on the Hydril Annular BOP mean few areas are subjected to wear. The BOP is safer and more efficient, requiring less maintenance and less downtime. A Long Piston with a length to diameter ratio approaching one eliminates tendencies to cock and bind during operations with off-center pipe or unevenly distributed accumulations of sand, cuttings, or other elements. This design enhances the ability of the packing unit to reopen to full bore position. The Conical Bowl Design of the Piston provides a simple and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer life results. A Field Replaceable Wear Plate in the BOP Head serves as an upper non-sealing wear surface for the movement of the packing unit, making field repair fast and economical. Maximum Packing Unit Life is possible with the provision
for measuring piston stroke. This measurement indicates remaining packing unit life without disassembly and ensures the longest and safest use of the packing unit. Two Choices of Packing Unit Rubber Compounds permit more flexible applications. The Screwed Head Design of the GK BOP is a simple, efficient, and strong method of connecting the head to the body for safe operation with no loose parts to be lost down the hole or overboard. The Latched Head Design is available on the GK, 13-5/8"5000 and larger BOPs. It provides fast access to packing units and seals for minimum downtime with no loose parts to be lost down hole or overboard. Large Pressure Energized Seals are used for dynamically sealing piston chambers to provide safe operation, long seal life, and less maintenance. Piston Sealing Surfaces Protected by Operating Fluid lowers friction and protects against galling and wear to increase seal life and reduce maintenance time. The Operating Chambers are Tested to Full BOP Working Pressure to ensure strength, reliability, and the ability to over-pressurize the chambers in emergencies. Meets NACE MR-01-75 Material Standards for resistance to sulfide stress cracking.

Operation of the GK® Blowout Preventer
Conventional Ram BOP Operational Data Chart
The GK BOP has been developed especially for use on surface installations but it is also used subsea. Standard operation requires both opening and closing pressure. Seal off is effected by hydraulic pressure applied to the closing chamber which raises the piston, forcing the packing unit into a sealing engagement. Any normal closing unit having a separate pressure regulator valve for the annular BOP and sufficient accumulator volume can be used to operate the GK. The GK is designed to be well pressure assisted in maintaining packing unit seal off once initial seal off has been effected. As well pressure further increases, closure is maintained by well pressure alone. Exceptions are the GK 7-1/16"-15,000 and 20,000 psi which are not well pressure assisted and closing pressure must be maintained on the BOP to assure seal off. (Refer to the operators manual for closing pressure curves.) 13-5/8”-10,000 psi Ram BOP Manual Lock illustrated

During well control operations, drill pipe can be rotated and tool joints stripped through a closed packing unit, while maintaining a full seal on the pipe. Longest packing unit life is obtained by adjusting the closing chamber pressure just low enough to maintain a seal on the drill pipe with a slight amount of drilling fluid leakage as the tool joint passes through the packing unit. This leakage indicates the lowest usable closing pressure for minimum packing unit wear and provides lubrication for the drill pipe motion through the packing unit.The packing unit life is reduced when used for stripping operations. The pressure regulator valve should be set to maintain the proper closing chamber pressure. If the pressure regulator
valve cannot respond fast enough for effective control, an accumulator (surge absorber) should be installed in the closing chamber control line adjacent to the BOP – precharge the accumulator to 50% of the closing pressure required. In subsea operations it is sometimes advisable to add an accumulator to the opening chamber line to prevent undesirable pressure variations with certain control system circuits.

difficulties at low pressures, especially in cold temperatures. The results of Hydril's new bonnet seal design improves seal integrity at both low and high pressures and lowers bonnet bolt torque significantly to 1500 - 2000 ft.-lbs. Hydril's original bonnet seal consists of a single seal ring installed in a groove in the bonnet face (see Figure A). Hydril's new bonnet seal design consists of a set of special compound O-rings installed in a seal ring carrier. Conversion of the BOPs containing the original style bonnet seal to the new bonnet seal requires removal of the bonnet, machining a new cavity for the new seal ring carrier, and installing the seal ring carrier and the O-rings in the cavity as shown in Figure B.

Conversion of Hydril High Pressure Ram BOPs to accept New Bonnet Seal Improves Seal Integrity and Lowers Bonnet Bolt Torque. Based on Hydril's record of providing the newest and most advanced designs in blowout prevention equipment, Hydril has again met the challenge by developing a new patented bonnet seal that overcomes bonnet gap problems caused by high pressures. Minimizing these gaps currently requires the use of very high BOP bonnet bolt torques on high pressure BOPs. Seal gap problems become more severe in both cold weather and high temperature applications. Standard high pressure seals tend to loose their preload without internal pressure in the BOP which sometimes causes sealing

HYDRIL MSP 29-1/2-500 PSI
The MSP Annular Blowout Preventer is applicable to subsea or surface installations requiring a 2000 psi universal blowout preventer. As proven by its many field installations, it will deliver long, dependable service life. This BOP will seal off drill pipe, kelly, tool joints or tubing and wireline or completely shut off the open hole to full rated pressure. The following outstanding features of the MSP BOP make it qualified to meet the industry's need for simple and reliable blowout protection. A helicopter lift model of the MSP 21-1/4–2000 is also available. The Screwed Head Design of the MSP BOP is a simple, efficient, and strong method of connecting the head to the body for safe operation with no loose parts to be lost down the hole or overboard. The Latched Head Design which is optional on the MSP 21-1/4–2000 BOP provides fast, positive access to the packing unit and seals for minimum maintenance time. Only Two Moving Parts (piston and packing unit) on the Hydril Annular BOP mean few areas are subjected to wear. The BOP is thus a safer and more efficient mechanism requiring less maintenance and less downtime. Back to Front Feedable Rubber on the Packing Unit enables the packing unit to close and seal on almost any shape in the drillstring or close off the open bore and to strip tool joints under pressure. This safety feature permits confident closure of the BOP at the initial indication of a kick without the delay of locating the tool joint. The Conical Bowl Design of the Piston provides a simple and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer equipment life results. A Field Replaceable Wear Plate in the BOP Head serves as an upper non-sealing wear surface for the movement of the packing unit, making field repair fast and economical.
The MSP 29-1/2"-500 psi, developed for use on surface installations, is a large bore annular type diverter whose 29-1/2" bore permits hole to be drilled full bore with diverter protection. Its large bore permits the setting of large size surface casing without removing the diverter. Thus it is always ready for venting gas flows. Utilizing computerized finite element techniques, the original design of the MSP 29-1/2"-500 has been revamped to provide a unit made up of fewer parts to reduce cost. This unit may be ordered for use in standard service (temperate climates) or for use in cold environments such as the North Sea, Siberia, and Alaska where low temperature metallurgy may be required.

HYDRIL
This MSP provides an effective means of rerouting the flow of shallow, low-pressure gas. The MSP 29-1/2"-500 can be used either as a diverter or a 500 psi annular BOP. Only Two Moving Parts (piston and packing unit) on the Hydril Annular Diverter mean few surfaces are subjected to wear. The Diverter is thus a safer and simpler mechanism requiring less maintenance and less downtime. Back to Front Feedable Rubber on the Packing Unit enables the packing unit to close and seal on almost any shape in the drillstring or close off the open bore and strip tool joints under pressure. This safety feature permits confident closure of the MSP-29-1/2"-500 at the initial indication of kick without the delay of locating the tool joint. The Conical Bowl Design of the Piston provides a simple and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer equipment life results.
The HVR gives a universal seal off feature especially useful on tapered drill strings and drill pipe that does not have a constant diameter over its length. Two ram BOPs with HVRs can be used on a tapered string to provide a backup for all drill pipe sizes. This application eliminates having one pipe ram for small diameter pipe and one for large diameter pipe. If a BOP stack is assembled with a blind or blind/shear ram and two sets of Hydril Variable Rams 3-1/2"-6" size, the HVRs will seal on the drill pipe from 3-1/2" to 5-1/2", providing the backup seal off capability needed on a tapered string. The HVR is therefore ideally suited for subsea use by expanding the seal off capability of one ram assembly within a BOP.
INTERLOCKING I-BEAM INSERTS The HVR has a variable front packer with interlocking I-beam inserts molded into the rubber. These inserts confine the rubber within the packer and against the pipe thus preventing extrusion of the sealing element. During seal off on small diameter pipe, the inserts move radially inward to contact. On large diameter pipe the inserts are displaced into the front packer. Application of load by the BOP operator squeezes the sealing element within the confines of the inserts and the pipe O.D. This action establishes a steel contained sealing element. A key feature is automatic adaptation to the pipe size as the ram closes and seals off.
LARGE VOLUME OF FEEDABLE RUBBER The ram block upper seal provides a large volume of feedable rubber to deliver a long and dependable service life. The HVR operates inside standard Hydril ram blowout preventers and utilizes the standard hydraulic operator. This design permits interchangeability with fixed size pipe rams, casing rams and/or blind rams at any time.
and the Manual Lock Model. The automatic MPL ensures a positive mechanical lock at all positions of the variable ram. This means the MPL automatically compensates for the different positions the HVR attains when sealing on different pipe sizes.
LABORATORY TESTED . . . FIELD PROVEN The Hydril Variable Ram functional reliability has been proven by extensive field use and testing. HVR field tests have been conducted on wells operated by major oil companies. Tests include fatigue testing, which simulated over a year and a half of service by numerous cyclic operations and pressure tests of the ram packers. Ram BOP sizes and applicable HVR seal off ranges are listed below.

Operation of the MSP™ Diverter/BOP
Ram Sizes and Styles These types of rams are available: 1. Type: Blind Rams (CSO)-Complete Shut-off; Blind/Shear Rams; Pipe Rams; Tubing Rams; Casing Rams, Variable Rams (HVR's); Single Rams and Single Offset Rams, and Dual Offset Rams for multiple completions are also available. Blind Rams can be provided on all BOPs. Shear Rams may require larger than standard operator size.
2. Specify location of each set of rams when ordering double preventers. Pipe/hanging rams equipped with special hardened steel inserts which permit drill pipe hangoff are standard for 13-5/8"-15,000, 18-3/4"-10,000, and 18-3/4"-15,000 BOPs and are optional for 13-5/8"5000 and 10,000, 20-3/4"-3000, 21-1/4"-2000 and 21-1/4"-5000 BOPs.
The MSP Diverter/BOP has been developed as a simple, reliable unit for moderate pressure drilling service, remedial work, and well servicing. It can be used on surface and subsea installations. MSP 21-1/4"-2000 operation requires both opening and closing pressure. The MSP 29-1/2"-500 requires only closing pressure. Seal off is effected by hydraulic pressure applied to the closing chamber that raises the piston, moving the packing unit radially inward into a sealing engagement. Any normal closing unit having a separate regulator valve for the annular BOP and sufficient accumulator volume can be used to operate the MSP.
STRIPPING Cylindrical pipe sections can be rotated and standard size tool joints can be safely stripped though the closed blowout preventer packing unit. The pressure applied to the closing chamber should be low enough to allow a slight leakage of drilling fluid as the tool joint passes through the closed packing unit. The drilling fluid lubricates and cools the packing unit, reducing wear caused by rotation or stripping of pipe. Overall packing unit life is reduced when used in stripping operations. The operation/maintenance manual for the specific MSP model provides specifications and functional guidelines.

OPERATION AS A DIVERTER
OPERATION AS A BOP
When using the MSP as a Diverter during top hole drilling, the primary purpose is to divert well flows away from the rig and personnel. This application avoids shutting in the well, but instead permits routing of the flow to a safe distance on the down wind side of the rig. In this application, the MSP is attached directly to the drive or conductor pipe. Vent lines typically are installed directly below the diverter. The lines should be sized in accordance with API standards to prevent excessive well bore back pressure buildup. This may be accomplished by using a Hydril drilling spool between the diverter and the conductor pipe. The Hydril SXV Spool, described on page 38 of this catalog provides integral venting without external valves. If valves are to be used in the diverter system, standards set forth in API RP64 (Recommended Practice for Diverter Systems Equipment and Operation) should be followed.
When using the MSP as an Annular Blowout Preventer, it may be hooked up as shown (above, right). In this mode, well control operations can be conducted within the MSP's working pressure range In either mode, pressure applied to the closing chamber raises the piston closing the packing unit to effect the seal between the packing unit and pipe. Well pressure or test pressure also acts on the MSP 21-1/4"-2000 piston below the sealed off packing unit and further increases the closing force acting on the packing unit. The MSP 29-1/2"-500 is not wellbore assisted.

MPL COMPONENTS
Motion of the piston and tail rod during closing or opening the ram causes the lock nut to rotate. The fast lead, six path helical thread rotates the nut three turns per foot of travel.
The component parts of the MPL utilize basic mechanisms and proven techniques to achieve reliable and positive automatic multiple position locking. The tail rod is threaded with a fast lead, six path, helical thread. These threads make three turns per foot. The mating lock nut and clutch assembly screws onto the tail rod. Tail rod linear motion causes the lock nut to rotate as the piston moves to close or open the ram. The clutch assembly permits or prevents lock nut rotation. Preventing lock nut rotation prevents piston motion. The clutch assembly allows unrestrained closing motion. Application of opening pressure disengages the clutchassembly permitting opening motion.
LOCKOUT DEVICE
Incorporated in the MPL is provision for testing the locking mechanism. Manually operated lockout devices prevent opening pressure from disengaging the clutch assembly. Application of opening pressure then simulates opening forces applied to the ram thus testing proper functioning of the lock. The lockout device position is visually indicated.

MANUAL LOCKING The manual type lock is shown fully locked. The manual lock can be set after the ram has been hydraulically closed, to ensure retention of seal-off. Clockwise rotation of the tail rod locks the ram and counter-clockwise rotation unlocks it. The ram can also be closed manually, should failure of the hydraulic system occur. When the ram is open, clockwise rotation of the tail rod closes the ram and locks it. The ram must be opened hydraulically after it has been unlocked. The screw on the manual lock uses a left hand heavy-duty acme-type thread and is located within the BOP, where it is protected from weather, corrosion and external damage. The thread is protected and lubricated by hydraulic operating fluid for minimum torque requirement. Setting of the manual lock, after having closed the rams hydraulically, is facilitated by reducing the closing pressure. Do not reduce the closing pressure when hanging off drillpipe on the ram blocks. Ram seal is ensured by the wellbore pressure.

INITIAL CLOSING PRESSURE (PSI) REQUIRED FOR MSP 29-1/2”-500 BOP/DIVERTER
HYDRIL OFFERS A CHOICE OF AUTOMATIC MULTIPLE POSITION LOCKING OR MANUAL LOCKING ON RAM BOPS. Hydril Ram Blowout Preventers are available with automatic Multiple-Position Ram Locking. Multiple-Position Locking (MPL) allows the ram to seal off with optimum seal squeeze at every closure. MPL automatically locks and maintains the ram closed with the optimum rubber pressure required for seal off in the front packer and upper seal. Front packer seal wear (on any ram BOP) requires a different ram locking position with each closure to ensure an effective seal off. Multiple-Position Locking is required to ensure retention of that seal off position. A mechanical lock is automatically set each time the ram is closed. Ram closure is accomplished by applying hydraulic pressure to the closing chamber which moves the ram to a seal off position. The locking system maintains the ram mechanically locked while seal off is retained even after releasing closing pressure. The ram is opened only by application of opening pressure which releases the locking system automatically and opens the ram, simultaneously.

Closing Pressure 500 psi Wellbore
HOW MPL WORKS The figure above shows the ram maintained closed and sealed off by the MPL. Hydraulic closing pressure has been released. The Hydril Ram Blowout Preventer with MPL automatically maintains ram closure and seal off. MPL will maintain the required rubber pressure in the front packer and upper seal to ensure a seal off of rated working pressure. MPL will maintain the seal off without closing pressure and with the opening forces created by hanging the drill string on the ram. Locking and unlocking of the MPL are controlled by a unidirectional clutch mechanism and a lock nut. The unidirectional clutch mechanism maintains the nut and ram in a locked position until the clutch is disengaged by application of opening pressure. Hydraulic opening pressure disengages the clutch plates to permit the lock nut to rotate freely and the ram to open.

11. Manual Locking utilizes a heavy-duty acme thread to manually lock the ram in a sealed-off position or to manually close the ram if the hydraulic system is inoperative. 12. Fluid Connections and Hydraulic Passages are internal to the bonnets and body and preclude damage during moving and handling operations. 13. Connector Ring Grooves are stainless steel lined for all connectors (top, bottom and side outlets) for corrosion resistance of the sealing surface. 14. Ram Compartment is self-draining. 15. Bonnet Seal utilizes field proven material in an integrated seal design which combines the seal and backup ring for reliability and long life. An advanced pressure energized bonnet seal for high pressure BOP’s providing improved seal integrity and lower bolt torques is also available. 16. Piston Rod Mud Seal is a rugged, field-proven, integrally designed lip seal and backup ring retained in the bonnet by a stainless steel spiral lock ring. 17. Secondary (Emergency) Piston Rod Packing provides an emergency piston rod seal for use in the event of primary seal leakage at a time when repair cannot be immediately effected, except in Subsea BOPs. 18. A Weephole to atmosphere isolates wellbore pressure, indicates when seal is achieved and possible leakage in the primary seat. (Shown out of position.)

19. Piston Seals are of a lip-type design and are pressureenergized to provide a reliable seal of the piston to form the operating chambers of the BOP. 20. Side Outlets for choke/kill lines are available on all drilling ram models. Two outlets, one on each side, may be placed below each ram. In single and double configurations, outlets may be placed below the upper and lower ram, below the bottom ram only, or below the top ram only, therefore providing great versatility in stack design. 21. Single and Double Configurations are available with a choice of American Petroleum Institute (API) flanged, studded or clamp hub connections. This allows for the most economical use of space for operation and service. (Not shown.) 22. Bonnet Bolts are sized for easy torquing and arranged for reliable seal between bonnet and body. This prevents excessive distortion during high pressure seal off. (See Torque Chart on page 35.) 23. Bonnet Bolt Retainers keep the bonnet bolts in the bonnet while servicing the BOP. 24. Guide Rods align ram with bonnet compartment, preventing damage to the ram, piston rod or bonnets while retracting the rams. 25. Ram Seal Off is retained by wellbore pressure. Closing forces are not required to retain an established ram seal off.

1. The Ram Body has controlled and predictable structural hardness and strength throughout the pressure vessel. Hydril pressure vessel material has equal strength along all axes to provide reliable strength and resistance to sulfide stress cracking in hydrogen sulfide service. These materials have high impact strength for low temperature service. Advanced design techniques such as Finite Element Method of Structural Analysis give a highly reliable BOP with the desired safety factors. 2. The Ram Assembly provides reliable seal off of the wellbore for security and safety. The Ram accommodates a large volume of feedable rubber in the front packer and upper seal for long service life. 3. The Field Replaceable Seal Seat provides a smooth sealing surface for the ram upper seal. The seal seat utilizes specially selected and performance effective materials for maximum service life. The field replaceable seal seat eliminates shop welding, stress relieving, and machining for repair, thus reducing downtime and direct repair costs. 4. Hinged Bonnets swing completely clear of overhead restrictions (such as another BOP) and provide easy access for rapid ram change to reduce downtime.
24. Ram Block Guide Rods
13-5/8"-10,000 psi Ram BOP Manual Lock illustrated
5. Load Hinges separate from the fluid hinge and are equipped with self-lubricated bearings to support the full weight of the bonnet for quick and easy opening of the bonnet. 6. Fluid Hinges, separate from the load hinges, connect the control fluid passages between the body and bonnets. This arrangement provides a reliable hydraulic seal and permits full pressure testing and ram operation with the bonnets open. The fluid hinges and bonnet hinges contain all the seals necessary for this function and may be removed rapidly for simple, economical repair. 7. Replaceable Cylinder Liner has a corrosion and wear resistant bore for reliable piston operation. The cylinder liner is easily field replaceable or repairable for reduced maintenance cost and downtime. 8. Piston and Piston Rod Assembly are one piece for strength and reliability in closing and opening the ram which results in a secure operating assembly. 9. Choice of Ram Locks – Automatic Multiple-Position Locking (MPL) or Manual Locking is available on Ram BOPs. 10. Multiple-Position Locking (MPL) utilizes a reliable hydraulically-actuated mechanical clutch mechanism to automatically lock the rams in a seal off position.

Annular BOP Packing Units
One of the most important features of Hydril Annular Blowout Preventers is the packing unit. These reliable units are manufactured by Hydril from high-quality rubber material reinforced with flanged steel segments. Each size packing unit has a large volume of tough, feedable packing material sufficient to meet most requirements.
Cutaway Drawing Showing How Rubber is Molded Around Steel Segments
The molded-in steel segments have flanges at the top and bottom. These segments anchor the packing unit within the BOP and control rubber extrusion and flow when sealing off well pressures. Since the rubber is confined and kept under compression, it is resistant to tears, cuts, and abrasions. In the open position, the inside diameter of the packing unit is flush with the full bore of the preventer; bits, drill collars, or reamers pass through freely. The packing unit is squeezed inward when closing pressure is applied to the piston. The bore of the packing unit conforms automatically in size and shape and seals off any part of the drillstring or seals off completely if the tools are out of the hole. Hydril manufactures packing units for the annular BOPs at its own factory. This allows Hydril to maintain rigid quality control of packing units.
HYDRIL PACKING UNITS – FULLY FACTORY TESTED Each Hydril packing unit is factory tested in a BOP prior to shipment. The packing unit is tested to 50% of working pressure on open hole and 100% on pipe. The Certified Test Seal on the packing unit ensures that the unit meets the acceptance requirements based on years of experience and development in designing blowout preventers for reliable well control.
Ram Blowout Preventers
SELECTION Because of the importance of the packing unit to the operation of the blowout preventer and to the safety of crew and rig, only genuine Hydril packing units should be used as replacements for original equipment. All Hydril packing units are tested to full rated pressure inside a test BOP at the factory as part of rigid standard acceptance tests before being furnished to the consumer. Packing units for Hydril BOPs are manufactured from compounded natural rubber or nitrile rubber. Natural Rubber is compounded for drilling with water-base drilling fluids. Natural rubber can be used at operating temperatures between -30°F to 225°F (-35°C to 107°C). When properly applied, the compounded natural rubber packing unit will usually provide the longest service life. This all-black packing unit is identified by a serial number with a suffix "NR". Nitrile Rubber (a synthetic compound) is for use with oil-base or oil-additive drilling fluids. It provides the best service with oil-base muds, when operated at temperatures between 30°F to 180°F (-1°C to 82°C). The nitrile rubber packing unit is identified by a red color band and a serial number with the suffix "NBR". Seals for Hydril BOPs are manufactured from a special nitrile rubber material which provides long, trouble-free service in sealing against oil, gas, or water. Expected H2S and CO2 service does not affect selection of packing unit material. H2S and CO2 service will reduce the service life of rubber products, but the best overall service life is obtained by matching the packing unit material with the requirements of the specific drilling fluid. Performance of elastomeric materials can vary significantly, depending on the nature and extent of exposure to hydrogen sulfide. The operator should monitor pressure sealing integrity frequently to assure no performance degradation has occurred. Storage Conditions are important for realizing the maximum life of the packing unit. Packing units should be stored in a cool, dry, dark storage area. Atmosphere, light and heat accelerate deterioration of rubber goods. It is also essential to practice "first-in, first-out" when storing packing units. Other significant storage factors are covered in the applicable Operator's Manual.

Annular BOP Packing Units
One of the most important features of Hydril Annular Blowout Preventers is the packing unit. These reliable units are manufactured by Hydril from high-quality rubber material reinforced with flanged steel segments. Each size packing unit has a large volume of tough, feedable packing material sufficient to meet most requirements.
Cutaway Drawing Showing How Rubber is Molded Around Steel Segments
The molded-in steel segments have flanges at the top and bottom. These segments anchor the packing unit within the BOP and control rubber extrusion and flow when sealing off well pressures. Since the rubber is confined and kept under compression, it is resistant to tears, cuts, and abrasions. In the open position, the inside diameter of the packing unit is flush with the full bore of the preventer; bits, drill collars, or reamers pass through freely. The packing unit is squeezed inward when closing pressure is applied to the piston. The bore of the packing unit conforms automatically in size and shape and seals off any part of the drillstring or seals off completely if the tools are out of the hole.

19. Piston Seals are of a lip-type design and are pressureenergized to provide a reliable seal of the piston to form the operating chambers of the BOP. 20. Side Outlets for choke/kill lines are available on all drilling ram models. Two outlets, one on each side, may be placed below each ram. In single and double configurations, outlets may be placed below the upper and lower ram, below the bottom ram only, or below the top ram only, therefore providing great versatility in stack design. 21. Single and Double Configurations are available with a choice of American Petroleum Institute (API) flanged, studded or clamp hub connections. This allows for the most economical use of space for operation and service. (Not shown.) 22. Bonnet Bolts are sized for easy torquing and arranged for reliable seal between bonnet and body. This prevents excessive distortion during high pressure seal off. (See Torque Chart on page 35.) 23. Bonnet Bolt Retainers keep the bonnet bolts in the bonnet while servicing the BOP. 24. Guide Rods align ram with bonnet compartment, preventing damage to the ram, piston rod or bonnets while retracting the rams. 25. Ram Seal Off is retained by wellbore pressure. Closing forces are not required to retain an established ram seal off.

INITIAL CLOSING PRESSURE (PSI) REQUIRED FOR MSP 29-1/2”-500 BOP/DIVERTER
HYDRIL OFFERS A CHOICE OF AUTOMATIC MULTIPLE POSITION LOCKING OR MANUAL LOCKING ON RAM BOPS. Hydril Ram Blowout Preventers are available with automatic Multiple-Position Ram Locking. Multiple-Position Locking (MPL) allows the ram to seal off with optimum seal squeeze at every closure. MPL automatically locks and maintains the ram closed with the optimum rubber pressure required for seal off in the front packer and upper seal. Front packer seal wear (on any ram BOP) requires a different ram locking position with each closure to ensure an effective seal off. Multiple-Position Locking is required to ensure retention of that seal off position. A mechanical lock is automatically set each time the ram is closed. Ram closure is accomplished by applying hydraulic pressure to the closing chamber which moves the ram to a seal off position. The locking system maintains the ram mechanically locked while seal off is retained even after releasing closing pressure. The ram is opened only by application of opening pressure which releases the locking system automatically and opens the ram, simultaneously.

Closing Pressure 500 psi Wellbore
HOW MPL WORKS The figure above shows the ram maintained closed and sealed off by the MPL. Hydraulic closing pressure has been released. The Hydril Ram Blowout Preventer with MPL automatically maintains ram closure and seal off. MPL will maintain the required rubber pressure in the front packer and upper seal to ensure a seal off of rated working pressure. MPL will maintain the seal off without closing pressure and with the opening forces created by hanging the drill string on the ram. Locking and unlocking of the MPL are controlled by a unidirectional clutch mechanism and a lock nut. The unidirectional clutch mechanism maintains the nut and ram in a locked position until the clutch is disengaged by application of opening pressure. Hydraulic opening pressure disengages the clutch plates to permit the lock nut to rotate freely and the ram to open.

MPL COMPONENTS
Motion of the piston and tail rod during closing or opening the ram causes the lock nut to rotate. The fast lead, six path helical thread rotates the nut three turns per foot of travel.
The component parts of the MPL utilize basic mechanisms and proven techniques to achieve reliable and positive automatic multiple position locking. The tail rod is threaded with a fast lead, six path, helical thread. These threads make three turns per foot. The mating lock nut and clutch assembly screws onto the tail rod. Tail rod linear motion causes the lock nut to rotate as the piston moves to close or open the ram. The clutch assembly permits or prevents lock nut rotation. Preventing lock nut rotation prevents piston motion. The clutch assembly allows unrestrained closing motion. Application of opening pressure disengages the clutchassembly permitting opening motion.
LOCKOUT DEVICE
Incorporated in the MPL is provision for testing the locking mechanism. Manually operated lockout devices prevent opening pressure from disengaging the clutch assembly. Application of opening pressure then simulates opening forces applied to the ram thus testing proper functioning of the lock. The lockout device position is visually indicated.

MANUAL LOCKING The manual type lock is shown fully locked. The manual lock can be set after the ram has been hydraulically closed, to ensure retention of seal-off. Clockwise rotation of the tail rod locks the ram and counter-clockwise rotation unlocks it. The ram can also be closed manually, should failure of the hydraulic system occur. When the ram is open, clockwise rotation of the tail rod closes the ram and locks it. The ram must be opened hydraulically after it has been unlocked. The screw on the manual lock uses a left hand heavy-duty acme-type thread and is located within the BOP, where it is protected from weather, corrosion and external damage. The thread is protected and lubricated by hydraulic operating fluid for minimum torque requirement. Setting of the manual lock, after having closed the rams hydraulically, is facilitated by reducing the closing pressure. Do not reduce the closing pressure when hanging off drillpipe on the ram blocks. Ram seal is ensured by the wellbore pressure.

Operation of the MSP™ Diverter/BOP
Ram Sizes and Styles These types of rams are available: 1. Type: Blind Rams (CSO)-Complete Shut-off; Blind/Shear Rams; Pipe Rams; Tubing Rams; Casing Rams, Variable Rams (HVR's); Single Rams and Single Offset Rams, and Dual Offset Rams for multiple completions are also available. Blind Rams can be provided on all BOPs. Shear Rams may require larger than standard operator size.
2. Specify location of each set of rams when ordering double preventers. Pipe/hanging rams equipped with special hardened steel inserts which permit drill pipe hangoff are standard for 13-5/8"-15,000, 18-3/4"-10,000, and 18-3/4"-15,000 BOPs and are optional for 13-5/8"5000 and 10,000, 20-3/4"-3000, 21-1/4"-2000 and 21-1/4"-5000 BOPs.
The MSP Diverter/BOP has been developed as a simple, reliable unit for moderate pressure drilling service, remedial work, and well servicing. It can be used on surface and subsea installations. MSP 21-1/4"-2000 operation requires both opening and closing pressure. The MSP 29-1/2"-500 requires only closing pressure. Seal off is effected by hydraulic pressure applied to the closing chamber that raises the piston, moving the packing unit radially inward into a sealing engagement. Any normal closing unit having a separate regulator valve for the annular BOP and sufficient accumulator volume can be used to operate the MSP.
STRIPPING Cylindrical pipe sections can be rotated and standard size tool joints can be safely stripped though the closed blowout preventer packing unit. The pressure applied to the closing chamber should be low enough to allow a slight leakage of drilling fluid as the tool joint passes through the closed packing unit. The drilling fluid lubricates and cools the packing unit, reducing wear caused by rotation or stripping of pipe. Overall packing unit life is reduced when used in stripping operations. The operation/maintenance manual for the specific MSP model provides specifications and functional guidelines.

OPERATION AS A DIVERTER
OPERATION AS A BOP
When using the MSP as a Diverter during top hole drilling, the primary purpose is to divert well flows away from the rig and personnel. This application avoids shutting in the well, but instead permits routing of the flow to a safe distance on the down wind side of the rig. In this application, the MSP is attached directly to the drive or conductor pipe. Vent lines typically are installed directly below the diverter. The lines should be sized in accordance with API standards to prevent excessive well bore back pressure buildup. This may be accomplished by using a Hydril drilling spool between the diverter and the conductor pipe. The Hydril SXV Spool, described on page 38 of this catalog provides integral venting without external valves. If valves are to be used in the diverter system, standards set forth in API RP64 (Recommended Practice for Diverter Systems Equipment and Operation) should be followed.
When using the MSP as an Annular Blowout Preventer, it may be hooked up as shown (above, right). In this mode, well control operations can be conducted within the MSP's working pressure range In either mode, pressure applied to the closing chamber raises the piston closing the packing unit to effect the seal between the packing unit and pipe. Well pressure or test pressure also acts on the MSP 21-1/4"-2000 piston below the sealed off packing unit and further increases the closing force acting on the packing unit. The MSP 29-1/2"-500 is not wellbore assisted.

The MSP Annular Blowout Preventer is applicable to subsea or surface installations requiring a 2000 psi universal blowout preventer. As proven by its many field installations, it will deliver long, dependable service life. This BOP will seal off drill pipe, kelly, tool joints or tubing and wireline or completely shut off the open hole to full rated pressure. The following outstanding features of the MSP BOP make it qualified to meet the industry's need for simple and reliable blowout protection. A helicopter lift model of the MSP 21-1/4–2000 is also available. The Screwed Head Design of the MSP BOP is a simple, efficient, and strong method of connecting the head to the body for safe operation with no loose parts to be lost down the hole or overboard. The Latched Head Design which is optional on the MSP 21-1/4–2000 BOP provides fast, positive access to the packing unit and seals for minimum maintenance time. Only Two Moving Parts (piston and packing unit) on the Hydril Annular BOP mean few areas are subjected to wear. The BOP is thus a safer and more efficient mechanism requiring less maintenance and less downtime. Back to Front Feedable Rubber on the Packing Unit enables the packing unit to close and seal on almost any shape in the drillstring or close off the open bore and to strip tool joints under pressure. This safety feature permits confident closure of the BOP at the initial indication of a kick without the delay of locating the tool joint. The Conical Bowl Design of the Piston provides a simple and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer equipment life results. A Field Replaceable Wear Plate in the BOP Head serves as an upper non-sealing wear surface for the movement of the packing unit, making field repair fast and economical.
The MSP 29-1/2"-500 psi, developed for use on surface installations, is a large bore annular type diverter whose 29-1/2" bore permits hole to be drilled full bore with diverter protection. Its large bore permits the setting of large size surface casing without removing the diverter. Thus it is always ready for venting gas flows. Utilizing computerized finite element techniques, the original design of the MSP 29-1/2"-500 has been revamped to provide a unit made up of fewer parts to reduce cost. This unit may be ordered for use in standard service (temperate climates) or for use in cold environments such as the North Sea, Siberia, and Alaska where low temperature metallurgy may be required.

This MSP provides an effective means of rerouting the flow of shallow, low-pressure gas. The MSP 29-1/2"-500 can be used either as a diverter or a 500 psi annular BOP. Only Two Moving Parts (piston and packing unit) on the Hydril Annular Diverter mean few surfaces are subjected to wear. The Diverter is thus a safer and simpler mechanism requiring less maintenance and less downtime. Back to Front Feedable Rubber on the Packing Unit enables the packing unit to close and seal on almost any shape in the drillstring or close off the open bore and strip tool joints under pressure. This safety feature permits confident closure of the MSP-29-1/2"-500 at the initial indication of kick without the delay of locating the tool joint. The Conical Bowl Design of the Piston provides a simple and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer equipment life results.
The HVR gives a universal seal off feature especially useful on tapered drill strings and drill pipe that does not have a constant diameter over its length. Two ram BOPs with HVRs can be used on a tapered string to provide a backup for all drill pipe sizes. This application eliminates having one pipe ram for small diameter pipe and one for large diameter pipe. If a BOP stack is assembled with a blind or blind/shear ram and two sets of Hydril Variable Rams 3-1/2"-6" size, the HVRs will seal on the drill pipe from 3-1/2" to 5-1/2", providing the backup seal off capability needed on a tapered string. The HVR is therefore ideally suited for subsea use by expanding the seal off capability of one ram assembly within a BOP.
INTERLOCKING I-BEAM INSERTS The HVR has a variable front packer with interlocking I-beam inserts molded into the rubber. These inserts confine the rubber within the packer and against the pipe thus preventing extrusion of the sealing element. During seal off on small diameter pipe, the inserts move radially inward to contact. On large diameter pipe the inserts are displaced into the front packer. Application of load by the BOP operator squeezes the sealing element within the confines of the inserts and the pipe O.D. This action establishes a steel contained sealing element. A key feature is automatic adaptation to the pipe size as the ram closes and seals off.
LARGE VOLUME OF FEEDABLE RUBBER The ram block upper seal provides a large volume of feedable rubber to deliver a long and dependable service life. The HVR operates inside standard Hydril ram blowout preventers and utilizes the standard hydraulic operator. This design permits interchangeability with fixed size pipe rams, casing rams and/or blind rams at any time.
and the Manual Lock Model. The automatic MPL ensures a positive mechanical lock at all positions of the variable ram. This means the MPL automatically compensates for the different positions the HVR attains when sealing on different pipe sizes.
LABORATORY TESTED . . . FIELD PROVEN The Hydril Variable Ram functional reliability has been proven by extensive field use and testing. HVR field tests have been conducted on wells operated by major oil companies. Tests include fatigue testing, which simulated over a year and a half of service by numerous cyclic operations and pressure tests of the ram packers. Ram BOP sizes and applicable HVR seal off ranges are listed below.

difficulties at low pressures, especially in cold temperatures. The results of Hydril's new bonnet seal design improves seal integrity at both low and high pressures and lowers bonnet bolt torque significantly to 1500 - 2000 ft.-lbs. Hydril's original bonnet seal consists of a single seal ring installed in a groove in the bonnet face (see Figure A). Hydril's new bonnet seal design consists of a set of special compound O-rings installed in a seal ring carrier. Conversion of the BOPs containing the original style bonnet seal to the new bonnet seal requires removal of the bonnet, machining a new cavity for the new seal ring carrier, and installing the seal ring carrier and the O-rings in the cavity as shown in Figure B.

Conversion of Hydril High Pressure Ram BOPs to accept New Bonnet Seal Improves Seal Integrity and Lowers Bonnet Bolt Torque. Based on Hydril's record of providing the newest and most advanced designs in blowout prevention equipment, Hydril has again met the challenge by developing a new patented bonnet seal that overcomes bonnet gap problems caused by high pressures. Minimizing these gaps currently requires the use of very high BOP bonnet bolt torques on high pressure BOPs. Seal gap problems become more severe in both cold weather and high temperature applications. Standard high pressure seals tend to loose their preload without internal pressure in the BOP which sometimes causes sealing

Operation of the GK® Blowout Preventer
Conventional Ram BOP Operational Data Chart
The GK BOP has been developed especially for use on surface installations but it is also used subsea. Standard operation requires both opening and closing pressure. Seal off is effected by hydraulic pressure applied to the closing chamber which raises the piston, forcing the packing unit into a sealing engagement. Any normal closing unit having a separate pressure regulator valve for the annular BOP and sufficient accumulator volume can be used to operate the GK. The GK is designed to be well pressure assisted in maintaining packing unit seal off once initial seal off has been effected. As well pressure further increases, closure is maintained by well pressure alone. Exceptions are the GK 7-1/16"-15,000 and 20,000 psi which are not well pressure assisted and closing pressure must be maintained on the BOP to assure seal off. (Refer to the operators manual for closing pressure curves.) 13-5/8”-10,000 psi Ram BOP Manual Lock illustrated

During well control operations, drill pipe can be rotated and tool joints stripped through a closed packing unit, while maintaining a full seal on the pipe. Longest packing unit life is obtained by adjusting the closing chamber pressure just low enough to maintain a seal on the drill pipe with a slight amount of drilling fluid leakage as the tool joint passes through the packing unit. This leakage indicates the lowest usable closing pressure for minimum packing unit wear and provides lubrication for the drill pipe motion through the packing unit.The packing unit life is reduced when used for stripping operations. The pressure regulator valve should be set to maintain the proper closing chamber pressure. If the pressure regulator
valve cannot respond fast enough for effective control, an accumulator (surge absorber) should be installed in the closing chamber control line adjacent to the BOP – precharge the accumulator to 50% of the closing pressure required. In subsea operations it is sometimes advisable to add an accumulator to the opening chamber line to prevent undesirable pressure variations with certain control system circuits.

AVERAGE CLOSING PRESSURE (PSI) TO ESTABLISH INITIAL SEAL OFF IN GK BLOWOUT PREVENTERS FOR SURFACE INSTALLATIONS ❍
The pressures above are a guideline. Maximum packing unit life will be realized by the use of the lowest closing pressure that will maintain a seal. For subsea applications, see the appropriate Operator's Manual for computation of best closing pressure.
Recommended test pipe for maximum packing unit life. ❍ Reference only replaced by GX

Cylinder Bore (in.) MPL The GK Annular Blowout Preventer was designed especially for surface installations and is also used on offshore platforms and subsea. The GK is a universal annular blowout preventer with a long record of proven, quality performance. Only Two Moving Parts (piston and packing unit) on the Hydril Annular BOP mean few areas are subjected to wear. The BOP is safer and more efficient, requiring less maintenance and less downtime. A Long Piston with a length to diameter ratio approaching one eliminates tendencies to cock and bind during operations with off-center pipe or unevenly distributed accumulations of sand, cuttings, or other elements. This design enhances the ability of the packing unit to reopen to full bore position. The Conical Bowl Design of the Piston provides a simple and efficient method of closing the packing unit. With the piston serving as a sealing surface against the rubber packing unit, there is no metal-to-metal wear on the sealing surface and thus longer life results. A Field Replaceable Wear Plate in the BOP Head serves as an upper non-sealing wear surface for the movement of the packing unit, making field repair fast and economical. Maximum Packing Unit Life is possible with the provision
for measuring piston stroke. This measurement indicates remaining packing unit life without disassembly and ensures the longest and safest use of the packing unit. Two Choices of Packing Unit Rubber Compounds permit more flexible applications. The Screwed Head Design of the GK BOP is a simple, efficient, and strong method of connecting the head to the body for safe operation with no loose parts to be lost down the hole or overboard. The Latched Head Design is available on the GK, 13-5/8"5000 and larger BOPs. It provides fast access to packing units and seals for minimum downtime with no loose parts to be lost down hole or overboard. Large Pressure Energized Seals are used for dynamically sealing piston chambers to provide safe operation, long seal life, and less maintenance. Piston Sealing Surfaces Protected by Operating Fluid lowers friction and protects against galling and wear to increase seal life and reduce maintenance time. The Operating Chambers are Tested to Full BOP Working Pressure to ensure strength, reliability, and the ability to over-pressurize the chambers in emergencies. Meets NACE MR-01-75 Material Standards for resistance to sulfide stress cracking.

Hydril Conventional Ram BOP Parts List
STRIPPING The design of the GX effectively controls positioning of the inserts. When stripping, the inserts remain fixed as the rubber flows in and out, allowing the alternating diameters of pipe and tool joints to pass through the closed packing unit. This results in a dramatic increase of the GX packing unit stripping life – to approximately twice that of similar sized annular BOPs.

HYDRIL
BALANCED PISTON Piston stability is assured by Hydril's time proven long piston design with contact points providing a length-to-diameter ratio approaching 1. This design eliminates any tendency to cock and bind during operations with off-center pipe or unevenly distributed accumulations of sand or cuttings. The GX piston is completely balanced. The opening and closing chamber areas are of equal size. This equalizes the hydrostatic forces exerted on the piston by the control fluid column in subsea operations. The result is a BOP that utilizes a constant closing pressure regardless of water depth or mud weight. This piston design is such that the closing pressure requirements are virtually independent of well bore pressures. Contoured angular tapers on the piston bowl compress and displace the reservoir of feedable rubber in the back of the packing unit. This design assures optimum rubber feeding and closing efficiency. Movement of the piston to the open position allows the packing unit to relax to full open bore.
EXTRA PACKING UNIT LIFE The heart of any annular BOP is its packing unit – and the GX is no exception. Its packing unit has a greatly increased reservoir of high-quality feedable rubber. Because the reservoir of feedable rubber is larger, the GX permits continuous rubber feeding as the boresurface wears. The packing units reinforcing flanged steel inserts are driven by the rubber during closure and quickly reach a fixed position where they form a steel ring to support the rubber from upward motion under wellbore pressure. Once the inserts reach their fixed position, rubber continues to flow inward, effecting a positive seal off on the drill string or the open bore. The rubber is primarily in compression and is therefore resistant to tears, cuts and abrasions. The steel inserts stabilize the rubber and control the flow pattern to minimize rubber stress. Packing unit life due to routine testing at full working pressure has been increased beyond previous levels. Because Hydril Company manufactures all its own packing units, rigid quality control is assured and field performance enhanced.
MORE PRECISE CONTROL Tool joints can be stripped through the closed packing unit while a full seal is maintained on the pipe. The GX packing unit design permits precise control of packoff tightness, regardless of wellbore pressures. This allows a slight drilling fluid leakage to be achieved during stripping operations to provide lubrication, optimize pull through forces and prolong packing unit life. The result is the ability to strip long strings of pipe and tool joints in or out of the hole at higher wellbore pressures.

Hydril GX™ 10,000 psi Annular Blowout Preventer
Hydril's complete line of annular blowout preventers is based on more than 55 years of application experience in all BOP types, sizes, and pressure ranges. There is a Hydril Annular BOP to meet most operational requirements in the petroleum industry today, both on the surface and subsea. Hydril designs are durable for dependable and efficient operation. A standard annular BOP will strip drill pipe and tool joints. The packing unit life is reduced when used for stripping operations. It will also close off the annulus or open hole to full working pressure. The Hydril Annular BOP provides quick, positive closing action with simplified controls to keep drilling fluids in the hole when a blowout threatens. The universal seal off feature of the annular blowout preventer permits closure and seal off on drill pipe, kelly, tool joints, or tubing and wireline as well as the open hole. Maintenance of the BOP is easy, rapid, and economical with the use of standard tools. The Low Alloy Steel Pressure Vessel represents Hydril's 50 years of experience in producing BOPs to provide optimum strength and stress distribution control. Full-spectrum testing meeting or exceeding API requirements ensures that the desired safety factors and reliability are provided in each unit.
Finite Element Analysis of the body design is the most advanced, in-depth technique of pressure vessel design analysis and ensures a structurally sound body configuration. Shell (Hydrostatic) Testing of the BOP body meets the API accepted industry standards to provide a safe, reliable blowout preventer. API 16A is the latest API specification covering drill through equipment. Hydril is licensed to manufacture Blowout Preventers to these exacting standards. In addition, Hydril preventers may also be certified by such certifying authorities as Det Norske Veritas (DNV), American Bureau or Shipping (ABS), or Lloyds of London. Operating Chambers are Pressure Tested to rated working pressure of the BOP or 3000 psi, whichever is greater. This ensures strength, reliability, safety, and the ability to over-pressure the chambers in well-control situations. Stainless Steel and Inconel-lined Ring Grooves are available as options.

Simplicity is derived from the patented integral vent design that eliminates extraneous valves and interconnections. One command, a hydraulic signal, does it all. Upward motion of the piston stops the flow of the well fluid and opens the vent line. Fast response time is ensured, since there is no waiting for valve functions. Risk of malfunction during component sequencing is eliminated. Subsea Diverter Stack permits subsea diverting, circulation of kill mud or shearing of pipe, and disconnecting of the riser as alternative means of dealing with shallow gas from a floating rig. 38

12’ or 16” Flow Selector is a massive two-position target for selecting port/starboard venting.
Subsea diverting provides safety advantages by dissipating destructive forces into the sea, remote from the rig. Surface support is spared from impact and erosion. Safety of personnel and rig is enhanced.
A Certified Test Label is on every Hydril packing unit. The label indicates the unit was tested at full pressure on pipe and 50 percent of pressure on open hole. Certifications of other tests are sent with the unit. Packaging resistant to both moisture and sunlight and a reinforced crate provide the best protection for shipping and storage. These measures ensure you will have the finest quality packing unit when you are ready to use it.
