Abstract

Abstract There is disclosed a landing tool for landing apparatus in a well at a selected location. An expander expands lugs into a groove in the tubing wall to position the landing tool and at the same time releases lugs which are securing a running tool to the landing tool. The running tool illustrated has locator dogs which while the tool is being run can retract into an out of the way position. Upon reverse movement of the running tool in the well these dogs are prevented from retracting until at a predetermined load a snap ring detent is overcome and thereafter movement of the running tool in the well in the original direction will result in the running tool being arrested upon engaging the first shoulder in the tubing. Continued movement in such direction of the running assembly moves a pusher into engagement with the expander on the landing tool to latch the landing tool in the well and release the running tool from the landing tool. Also shown is a pulling tool having a collet which can be run into the landing tool and engage an internal shoulder therein. Subsequent upward pull on the pulling tool will release the landing tool from the well tubing and witndraw it from the well.
