Liner Top Packers

Wellfirst liner top packers are engineered to anchor liner hangers in the casing seat and deliver a verified seal between the liner and the previous casing string. Raising, setting and retrieval behaviour can be matched to your well program, with element options covering standard and high-temperature wells.

Applications

Primary liner cementing, open-hole or cased-hole liner systems, tie-back operations requiring an isolated annulus.

How it saves you time

Consistent set performance reduces remedial squeeze work and keeps the rig moving to the next phase.

Enduro Liner Hanger Packer

The ENDUROTM RLH features proprietary SureSet and SafeSlip technology providing the most reliable hanger in both setting and retrieving operations. Designed to exceed expectations over a wide range of completion operations including, fracturing, gravel-packing, sand control, and primary completions. The ENDUROTM RLH is conveyed via tubing or drill pipe with the Enduro ST and Enduro RT running and setting tools, and are designed for extreme high torque operations, including rotating and drilling the liner into position. The ENDUROTM Liner Hanger Packer is a premium retrievable liner top packer that can be used in a wide variety of applications: as a production or isolation seal bore packer; vertical, deviated, and horizontal wells; gravel packing; fracturing; and hanging liners. The packer is designed for primary conditions - operable in high pressures and temperatures up to 7,500 psi (51.7 MPa) and 400°F (204°C). Due to the static nature of the mechanism, the sealing material is formed from a material rated at 400°F (204°C) in primary applications. The Solace Liner Packer can be configured with WELLFIRST proprietary Thermo Seal Packing Element Technology for use in static and dynamic applications up to 675°F (357°C) and 2,500 psi (17.2 MPa).

Key features
  • High temperature and pressure applications
  • SureSet™ — seal energized to replace seal efficiency over time
  • SafeSlip™ — unique dovetail slips energized to maintain maximum extension regardless of top or bottom pressure
  • Small footprint — a thermal tie-back adapter kit and one-piece internal mandrel eliminates the need to seal into a long tie-back and also allows the
  • THERMOnator™ thermal element refined over 20 years of thermal experience
  • Innovative pre-heating manufacturing process, results in less than 1% minimum initial seal degradation

Enduro Liner Top Packer

Enduro Liner Top Packer The Wellfirst Enduro RLP is a premium liner top seal that is designed for use in a wide variety of applications. The seal utilizes a proprietary blend of elastomer that is ideal for operation in primary conditions with high pressures and temperatures — up to 7,500 psi (51.7 MPa) and 400° F (204°C). When used in conjunction with the Enduro Running Tool and other liner circulation tools, the robust design is ideal for drilling in and circulating liners into position. A large beveled liner entry facilitates liner re-entry for workover or tractor operations.

Key features
  • Large bore liner top seal is suitable for drill-down operations
  • Available in standard, thermal, and sour gas configurations
  • Rated to 7,500 psi (51.7 MPa) and 400°F (204°C) primary and 2,500 psi (17.2 MPa) and 675°F (357°C) thermal Thermo Seal Packing Element For higher temperature static and dynamic applications — up to 675°F (357°C) and 2,500 psi (17.2 MPa) — the Thermal Sole Liner Top Seal Packer The chemically inert thermo seal material was tested to 675°F (357°C) and 2,500 psi (17.2 MPa).

Model SS Hydraulic Liner Setting Tool

Model SS Hydraulic Liner Setting Tool The Model SS Hydraulic Liner Setting Tool is used primarily for running and setting the Model S series of conventional and thermal liner packers and liner hangers using conventional tubing or drill pipe.

Key features
  • The compact, high strength design securely locks the liner to the setting tool
  • The setting tool allows rotation of the liner in order to facilitate running the
  • Circulation is possible through the setting tool and liner until the setting ball is inserted into the tubing string and lands on the ball seat. Once setting is complete, circulation between annulus and tubing through the setting tool is
  • adjustable, in order to accommodate the use of both thermal and conventional packer elements. The setting force at which the tool begins to apply pressure to the liner packer/hanger is also adjustable in order
  • as- sembly is run into the well. Normally, the setting ball would not be run in place in order to allow circulation if necessary . The liner may be rotated to assist in getting the liner to bottom in deviated wells or to facilitate sand clean out. Once at depth, the setting ball is dropped and allowed to gravitate to the seat, or the ball may be circulated to the seat. Once the ball is seated, the tubing is pressured up against the ball. At a predetermined differential pressure, the setting tool is activated and the liner packer/hanger begins to set. The tubing pressure is generally increased in stages (important when thermal elements are used) to allow sufficient time for the element to set securely. The tubing pressure is then increased to the preset differential pressure at which the ball seat shifts downward, opening up circulation ports.
