RETRIEVABLE LANDING METHOD AND ASSEMBLY FOR A WELL BORE Abstract of the Disclosure A retrievable landing method and assembly for lowering on a well string into a well bore a retrievable receptacle having a landing shoulder and securing it in position on a tubular member landing seat. The retriev- able receptacle is releasably coupled to the well string and after the retrievable receptacle landing shoulder engages the tubular member landing seat, the well string is manipulated to actuate the releasable coupling to release the well string for movement relative to the retrievable receptacle. Latch means associated with the retrievable receptacle are responsive to the well string manipulation to secure the retrievable receptacle sealingly with the well bore tubular member. Thereafter, if desired, hydraulic pressure may be applied between the retrievable receptacle and the well bore tubular member to test the seal, and tension and compression forces may be applied to the retrievable receptacle by manipulating the well string to assure that it is properly positioned and secured in the well bore tubular member.
