  • Method of screen or pipe expansion downhole without addition of pipe at the surface
    Patent number: 6899182
    Abstract: A method of streamlining expansion of long lengths of tubulars or screen is disclosed. In one embodiment, the expansion assembly is coupled with a length of pipe that acts as a weight and has a length longer than the anticipated section to be expanded. There is a stinger that fits into the pipe above the anchor and a seal to maintain sealing contact despite the downhole advance of the expansion assembly following each stroke of the expansion device and advance of a swage. By sequentially applying and removing pressure, the desired length is expanded downhole. Alternatively, coiled tubing is connected to the expansion assembly and weights that are above it and is paid out into the well as the expansion assembly descends after each stroke.
