Tejas hydraulic wireline valves are typically used in multi-string wells, where there is a lack of annular space to accommodate Tubing Retrievable safety valves.

Wireline valves are also used as a secondary valve when a TRSV becomes inoperable. Tejas offers hydraulic control solutions for 4 basic scenarios:

  • Scenario 1: TRSV Flapper is leaking, flow tube is moving and control line is holding pressure. Solution: Communicate hydraulic control line, lock-out flow tube and run WR-B8.
  • Scenario 2: TRSV Flow tube is not moving, but flapper is not leaking and control line is holding pressure.
    Solution: Communicate control line and run WR-RESTOR.
  • Scenario 3: TRSV Piston is leaking, flow tube is not holding, but control line is holding pressure. Solution: Communicate hydraulic control line, lock-out flow tube and run WR-B8.
  • Scenario 4: TRSV Control line is leaking to annulus.
    Solution: Run wellhead adaptor, run WR-REGAIN.

Wireline safety valves can be adapted to any wireline lock. We can provide you with the right solutions. Succeed with us!
