ABSTRACT OF THE DISCLOSURE Disclosed is a well latch for locking well tools in a well flow conductor. The latch housing has a pressure equaliz- ing passage extending through its wall. A valve controls flow through the equalizing passage. Keys, carried by the latch housing, are expanded outwardly into a locking groove of a well flow conductor to lock the well latch therein. A fishing neck, associated with the latch, permits retrieval of the latch. This abstract is neither intended to define the scope of the invention, which, of course, is measured by the claims, nor is it intended to be limiting in any way.
