ABSTRACT:
An elongated tubing hanger assembly includes a bottom hanger sub installed upright on the well head of a well, a sealing assembly disposed within the bottom hanger sub, a slip bowl removably disposed within the bottom hanger sub immediately above and seated upon the sealing assembly, an annular retaining ring disposed about the upper periphery of the slip bowl to apply a force downward against the slip bowl, a running sub temporarily installed into an upper end portion of the bottom hanger sub to apply force downward against the slip bowl to compress and expand annular seal elements of the sealing assembly radially inward into a sliding sealing relationship with the tubing during its insertion, a slip element applied on the tubing and seated in an opening through the slip bowl to support the tubing in the well bore and to apply downward force, due to the weight of the tubing in the well bore, against the slip bowl to compress and expand the annular seal elements radially inward into the sealing relationship with the tubing, and a top hanger sub for attachment to the upper end portion of the bottom hanger sub after removal of the running sub. An elongated tubing hanging method includes the steps of installing the running sub in the bottom hanger sub during insertion of the tubing, then applying the slip element to the tubing and seating it in the slip bowl once the tubing is inserted, and finally removing the running sub and replacing it with a top hanger sub.
