Cactus Wellhead Presentation...

Description

Agenda • Arrival/Welcome • Safety Orientation • Facility Tour • Presentation on Basic Wellhead and API Requirements • Lunch • Stack-up of MBU-LR Speed Head System/Conventional

Wellhead System/Overview of Frac Tree Equipment • Discussion | Q&A

Conventional Assemblies • Include the casing head, casing hangers, spool sections, tubing head, tubing hanger, valves and fittings • Provides safe and adequate means for supporting and attaching blowout control equipment during drilling • Provides sealing between casing strings and a connection for the Christmas tree • Requires manipulation of BOP’s with each added section • Tubulars suspended on “slips”

‘HPS’ Elastomer Secondary Seals Interference fit provides pressure energized seal. No plastic packing required. Springs in corners prevent extrusion

Large ID interference provides sealing on rough casing

Type ‘P’ Elastomer Seal Metal retainer rings prevent extrusion

Seal energized against casing with plastic packing injection

‘Dovetail’ Elastomer Seals Commonly used as test plug and large O.D. seals Dovetail shape locks seal into groove

Tapered edges help prevent extrusion

Wide seal surface provides improved sealing

Type ‘S’ Elastomer Seal Metal springs in corners to prevent extrusion

OD bump provides interference fit allowing seal to be pressure energized

API Flange Bolting • Flanges under pressure see a separation force equal to

the pressure times the area inside the ring gasket. F=PxA • This separation force is contained by the flange bolting. Thus, larger flanges and higher pressure flanges have larger bolts and/or more bolts. • As the bolt diameter increases the amount of make up torque goes up. • API 6A publishes recommended make-up torques for API bolting.

f = 0.07 Xylan Coated f = 0.13 Standard Lubricant

Initial Hanging Weight

Cold frac fluid causes casing to contract increasing load on slip

Pressure causes casing to balloon increasing load on slip

Product Specification Level (PSL) • PSL 1, PSL2, PSL3, PSL3G, PSL4 • Quality control requirements such as material

certifications, NDE, etc. that increase with the severity of service. • API 6A Annex A provides purchasing guidelines for selecting the proper PSL of Primary Equipment o Tubing Heads o Tubing Hangers o Tubing Head Adapters o Lower Master Valves

Performance Requirement (PR) • Cycle testing of the designs • Cycles may include pressure, loads, open-close, etc.

depending on product being tested • PR1 is minimum API cycle requirements found in the equipment section of the Specification 6A • PR2 adds additional cycles
