A liner and a hydraulic liner hanger setting arrangement for setting the liner in a well bore casing includes a setting tool having a tubular mandrel connected in a pipe string to extend through the hydraulic setting arrangement with the liner forming an outer housing surrounding the liner and to form a longitudinally extending annular recess therebetween with one end of the recess exposed to the well bore. Longitudinally extending piston means are sealably engaged in the recess with the piston means having a cone shaped end. Slips are releasably secured to the liner and means are provided to retain and to lock the piston means against premature retraction into the recess. A port in the housing communicates fluid pressure from the mandrel to the housing recess to move said piston means in the recess and engage the cone shaped end thereof with said slips to urge them into engagement with the well bore casing and thus secure the liner in position. Upon lowering the setting tool after the slips engage the casing, seal means on the piston means span the housing port and prevent communication to the recess from the port means when the piston is retracted back into the recess.

Apparatus and method of positioning and seating a retrievable insert landing assembly in a well bore tubular member with a left-hand threaded portion and having a sealing bore above or below the threaded portion. A releasable connecting arrangement secures the landing assembly in a well bore tubular member by engaging with the left-hand threaded portion in the tubular member. The landing assembly has an internal polished bore above the connecting arrangement which slidably and sealingly receives a tubular extension attached to a well string. The connecting arrangement is actuated by lowering the retrievable landing assembly within the tubular member to position the connecting arrangement adjacent the left-hand threaded portion and then lifting up on the landing assembly to lock it with the left-hand threaded portion. The well string is manipulated to actuate the releaseable coupling and disconnect the well string from the landing assembly after it is connected with the tubular member. To retrieve the landing assembly, the well string is manipulated to reconnect it with the retrievable landing assembly.
