pilot and section milling

baker oil tools

Pilot/Section Milling And Underreaming Tools Pilot milling is used to mill away complete sections of casing from either the wellhead or the liner hanger down to desired depth. This is done in conjunction with slot recovery on a fixed platform or to sidetrack in open hole below the casing shoe. METAL MUNCHER™ Turbo Mills provide extended blades for extra mill life. In most cases, pilot mills are capable of milling faster than the cuttings can be removed from the well. Section milling is used to remove the entire casing from a section of the well. Primarily section milling is done in conjunction with side tracking. Underreaming tools provide a means to go through a string of casing and open up the wellbore to a larger size. This can be done to improve a cement job or to expose new formation for a gravel pack. With any of these tools, it is recommended to run drilling jars, string mills for stabilization and shock subs to minimize vibration at the mill.

METAL MUNCHER™ Pilot Mill (Patented)

The METAL MUNCHER cutting structure provides a high rate of penetration. This will require a mud system capable of suspending the cuttings and carrying them to the surface. Special consideration should also be given to additional surface equipment to handle cuttings.

METAL MUNCHER Turbo Pilot Mill Product Family No. H15121 Description/Application

The METAL MUNCHER Pilot Mill is a high-performance mill used for milling washover pipe, casing and liners. The blade design continuously indexes a new cutting surface during milling. The insert design produces small, uniform and easyto-handle cuttings. The METAL MUNCHER Turbo Pilot Mill is available with 18-in. (457-mm) blades for slot recovery and long sections of casing to be milled.

METAL MUNCHER Pilot Mills are available to cut all standard sizes of casing and can be manufactured for any size. The mills can be manufactured with a connection down for milling applications that are too close to surface to run sufficient drill collar weight above the mill. Advantages • Increased rates of penetration

• Smaller cuttings

The METAL MUNCHER Pilot Mill should be run with a shock sub and sufficient drill collars to provide a wide range of milling weights. Both weight on mill and RPM will be determined by penetration rate, torque and cuttings removal. Pilot milling with METAL MUNCHER inserts should be treated as a machining process rather

• Long mill life • Turbo mill has extended blades for longer life • Hardened surfaces on areas of high wear

D™ Section Mill Product Family No. H15072

After milling for 3–5 ft (0.9–1.5 m), rotation continues and the pump is stopped while picking up off the casing. Pressure is allowed to equalize and rotation is stopped while picking up into the casing above the cut point. Pressure is then resumed and slacked off into the window. The resulting pressure drop verifies cutout and removes any shavings that may have entered the tool while making the window cut-out. Milling operations are continued.

Description/Application

The D Section Mill is an inside cutter and a section mill for sidetracking operations, as well as for milling perforated casing in production zones, loose joints of surface pipe and old casing for cementing new smaller casing to the formation. Operation

The D Section Mill should be run with a minimum of 10,000 lb (4 536 kg) of string weight in the bottomhole assembly (BHA). A bit or mill is run to help the tool enter the hole and stir cuttings during milling operation. The cut is started slowly, approximately 2–5 ft (0.6–1.5 m), above a coupling, then brought to a speed of 80+ RPM for the cut-out. The pump is started and the number of strokes increased to give a minimum pressure drop of 400 psi (27.6 bar) across the mandrel nozzle. During cut-out, approximately 1 in. (25.4 mm) is slacked off in 1/16-in. (1.6-mm) increments over a period of five to ten minutes. Once the pump gauge shows a definite pressure drop of 200 psi (13.8 bar), indicating that the casing has been cut through, pressure is increased until the annular velocity is sufficient to

Advantages • Operates hydraulically for fast, efficient downhole milling • Knife design reduces long stringers and removes casing in short chips for easy lift and removal by the drilling fluid pilot/section milling and underreaming tools

• All six knives are used for the initial cut-out, reducing cut-out time and minimizing the chance of bent or broken knives • Knives are dressed with METAL MUNCHER™

pilot section milling table and of contents Lockomatic™ Section Mill Dressed with METAL MUNCHER™ Cutter Product Family Nos. H15079–H15089 The LOCKOMATIC features a positive, direct lock and unlock mechanism for expanding drilling and milling tools. The LOCKOMATIC is as reliable as the drill string itself, because the lock is an extension of the drillstring. There is direct control of the tool–it's as if the lock were in the driller's hand. The LOCKOMATIC is unmatched for hole opening, underreaming and casing milling. Operation

Cutter arms are locked closed during run-in. Tool hang-up is prevented by a patented feature that damps off downhole hydrostatic pressure from the pressure ports. Circulation pressure moves the body and cutters upward by increasing the annular volume between the kelly and upper body. Because the patented LOCKOMATIC mandrel lock remains in place as part of the drillstring, the cutter arms cam out over the mandrel lugs, forcing the cutters to expand. On box down models when the bit is also cutting, applied drilling weight helps cutter expansion and maintains cutter expansion. On reaching gage, the cutters lock in place and stay locked as long as pressure and/or drilling weight is applied. The tool will not take true drilling weight until the cutter arms are locked out to full-gage cutting position. To retrieve, release pressure and pick up on tool. This retracts the mandrel lock from under the cutters. If chips and cuttings penetrate the collapsing mechanism, the pull of the draw works will force obstructions out of the way and close cutter arms. Springs and hydraulics are not involved. The LOCKOMATIC retrieves as easily as the drillstring. Tool sizes range from 3-3/4 in. (95.2 mm) closed gage to 48 in. (1 219.2 mm) open gage. Advantages • Fast run-in • Positive expansion • Positive locking • Positive unlocking • Multiple applications: hole opening, underreaming and casing cutting
