Cactus Wellhead Presentation

TRANSCRIPT

  • 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 BOPs with each added section

    Tubulars suspended on slips

  • Casing Heads

    C2 Casing Head (With FPOs)

    C2-BP Casing Head (With Two Lockscrews)

    C2 Casing Head (With LP Outlets and Baseplate)

    Test Port

    O-Ring Groove

    Available with Threaded or Slip-on and Welded bottoms

  • Tubing Heads

    CTH Tubing Head (With Secondary Bushing)

    CTH Tubing Head (With integral bottom)

    Test Port

  • Slip Type Casing Hangers

    C1 Casing Hanger and H Plate. Non-Automatic slip-

    type hanger. Used to suspend light to medium

    casing loads in C2 & C2BP Casing Heads

    C2 Casing Hanger. Standard automatic slip-type casing hanger. Used

    to suspend medium casing loads (50% joint strength) in C2 & C2BP

    Casing Heads

    C9 Casing Hanger. Heavy duty automatic slip-type casing hanger. Used to suspend high casing loads in C9 & C9BP

    Casing Heads

  • Mandrel Hangers

    One Piece Mandrel Hanger Fluted Mandrel Hanger

  • Tubing Hangers and Tubing Head Adapters

    CTH-2W wrap around hanger with BO2 coupling

    and BO2 tubing head adapter

  • HPS Elastomer Secondary Seals

    Springs in corners prevent extrusion

    Large ID interference provides sealing on rough casing

    Interference fit provides pressure energized seal. No plastic packing required.

  • Type P Elastomer Seal

    Metal retainer rings prevent extrusion

    Seal energized against casing with plastic packing injection

  • Dovetail Elastomer Seals

    Dovetail shape locks seal into groove

    Wide seal surface provides improved sealing

    Tapered edges help prevent extrusion

    Commonly used as test plug and large O.D. seals

  • Type S Elastomer Seal

    Metal springs in corners to prevent extrusion

    OD bump provides interference fit allowing seal to be pressure energized

  • Lockscrews

    Integral Lockscrew Threaded Lockscrew

  • API Ring Gaskets

    R Gasket 5,000 PSI

    RX Gasket 5,000 PSI

    BX Gasket 10,000-15,000 PSI

  • Wellhead/Christmas Tree Safety Back Pressure Valves

  • Wellhead/Christmas Tree Safety Body Fitting

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

    the pressure times the area inside the ring gasket. F = P x A 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

  • Casing Effects During Frac

    Initial Hanging Weight

    Cold frac fluid causes casing to contract increasing load on slip

    Pressure causes casing to balloon increasing load on slip
