TUBINGLESS ELECTRICAL SUBMERSIBLE PUMP INSTALLATION

摘要

A method of producing a well utilizes a submersible pump (31) run on a line (39), such as braided wire rope, that includes power conductors. The operator sets a packer (15) in the casing (ll), the packer having a check valve (19) and a tieback receptacle (27). The operator pressure tests the integrity of the casing above the packer, and if it passes, then runs the pump assembly on the line. The pump assembly has a shroud (59) with a downward extending extension that seals to the passage of the packer. If the pressure test of the casing fails, the operator runs a liner (51) into the well and engages the tieback receptacle. A smaller diameter pump is then lowered on a line into the liner and into engagement with the packer. The installing and retrieving of the pump is performed without the use of tubing.
