Abstract:
A string for drilling a well for installation and retrieval of ESP equipment without a rig. A well is drilled past the end of casing which has been cemented in place and extends to a wellhead at the surface. A receptacle is attached between production casing joints and run into the well 10. The receptacle is a tubular member with an inclined pocket formed on a side. At least one passage or port in the pocket intersects with a passage in receptacle with one or more lengths of tubing attached to the pocket. A wet connector within the production casing is landed in the receptacle and self aligns to the tubing. Electrical wires run within the tubing mate and lock with the wet connector. This allows an ESP to be run into the well via winch such that it stabs into the wet connector to receive power.
