    摘要： The inventions provide apparatus and methods for radially expanding a tubular deployed in a subterranean well by moving an expansion tool axially through the well. An expansion tool apparatus may have wear faces attached to at least a portion of the outer periphery of a mandrel for contacting the interior surface of the pipe, tube, or screen during expansion. According to another aspect of the invention, an expansion tool has a controlled egress seal between the outer surface of the tool and the inside surface of the expandable tubular. According to another aspect of the invention, an automatically variable diameter expansion tool is provided having a variable diameter cone, which expands, and contracts based on input from one or more sensors. According to another aspect of the invention, an apparatus and method for expanding a length of screen assembly in a subterranean wellbore is provided.

    摘要： Disclosed are apparatus and methods for movably securing a radially expandable sand-control screen jacket assembly to a base pipe. The screen jacket assembly is connected to the base pipe with a longitudinally moveable, sand-controlling joint. In use, the joint slides maintain a sand-controlling seal after radial expansion of the sand-control screen jacket assembly.
