  • Patent number: 4646842
    Abstract: 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.
