20080202748 | Tubingless Electrical Submersible Pump Installation - A method of producing a well utilizes a submersible pump run on a line, such as braided wire rope, that includes power conductors. The operator sets a packer in the casing, the packer having a check valve and a tieback receptacle. 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 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 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. | 08-28-2008 |
