Abstract: A well is abandoned by locating a plug in casing preferably at a location above where the quality of the cement job or the casing is questionable. A high powered laser is run in preferably on wireline and at a location above the plug is activated and rotated with the effect that the casing, cement behind the casing and the formation about the cement becomes molten and flows onto the plug where the mass cools and solidifies into a cohesive mass that spans the borehole and extends laterally into the formation. The mass is impervious and the abandonment procedure is complete. The plug can be bare or it can have layers above such as cement to protect the plug from molten temperatures until the mass cools sufficiently and solidifies.

Abstract: 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.
