PCR J-Latch Stinger Seal Assembly
Description
The PCR J-Latch Stinger Seal Assembly provides a positive latch for operating the sleeve valve inside a PCR Cement Retainer. It also isolates pressure between the tubing and annulus. The PCR J-Latch Stinger Seal Assembly locks into the retainer with a quarter turn to the left and releases with a quarter turn or multiple rotations to the right with an emergency shear release. It is recommended to run the PCR J-latch at shallow depths where hydrostatic or pump pressure may overcome available tubing string weight and pump the Stinger Seal Assembly out of the retainer causing a loss in pressure integrity
