Patent ID: 7128162

Claim:
An assembly for positioning a sleeve down hole in a hydrocarbon producing well, comprising: a sleeve having an interior surface, an exterior surface, a first end, a second end, and seals on the exterior surface of the sleeve, the sleeve being made of a material which is capable of expanding radially when pressure is applied to the interior surface; a running tool support rod extending axially through the sleeve, the support rod having a first end, a second end, an exterior surface; a first seal assembly positioned at the first end of the sleeve, the first seal assembly having more than one annular seal, each annular seal engaging the exterior surface of the support rod and the interior surface of sleeve; a second seal assembly positioned at the second end of the sleeve, the second seal assembly having more than one annular seal, each annular seal engaging the exterior surface of the support rod and the interior surface of sleeve; a first centralizer positioned at the first end of the sleeve, adapted to centralize the first end of the sleeve; a second centralizer positioned at the second end of the sleeve, adapted to centralize the second end of the sleeve; means for preventing an outermost seal of the second seal assembly from exiting the sleeve until the sleeve has been fully expanded and a preset pressure threshold has been reached; a fluid conduit extending through the support rod to a fluid feed inlet positioned between the first seal assembly and the second seal assembly; and means for selectively sending fluid through the fluid conduit to expand the sleeve by remote activation.
