Abstract
A method of use of a quick connect liner latch system assembly (QCLL). The QCLL latches each joint of a slick line deployed liner together quickly. This system can set an anchor in an existing well bore at a shallow depth and run a new liner in the well with a wire line unit using the QCLL system. The QCLL has two main sections that are locked together to form the full QCLL. The upper and lowers sections are locked together using a body lock ring. The units are not threaded together. The QCLL it has a latch with an inside diameter (ID) that is large enough to accommodate a standard liner wiper plug for the weight of the liner being run into the well.
