Latches

Weatherford offers a variety of wireline-retrievable latches for locking gas-lift, chemical-injection, and other special application devices into the appropriate side-
pocket mandrel. To retrieve the latch and attached valve, the operator jars the toolstring upward, shearing the release shear pin and disengaging the locking mechanism from the latch lug pocket profile.
Weatherford’s line of wireline-retrievable latches includes the BK-2, BEK-2, RK, RKP, RA, MT-2 and RM models. A ported ID is included in certain models for applications that require a communication path between the latch and an attached flow-controlled device, such as a circulating valve.
