    摘要: A method of sealing casing or liners in a wellbore is described. The stands of casing or liner receive a jacket bonded to the outer surface. Preferably, the jacket is a rubber compound bonded to the outer wall. The formulation responds to well fluids to swell at a predetermined rate. The casing or liner can also be expanded with a swage preferably prior to the onset of significant jacket swelling. Packers and sealing hangers can be optionally added at the extremes of the casing or liner string to further secure against channeling between adjacent formations.

    摘要: An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact.

    摘要: A method of attaching a tubular to an existing tubular in a well without reducing the inside diameter of the well is described. A shoe is attached to the lower end of the existing lowermost casing or tubular, generally prior to the casing being cemented or otherwise secured in the wellbore. The shoe has a diameter larger than the inside diameter of the casing or tubular to which it is attached. Subsequently, a liner is run in until its top end is in the enlarged diameter region of the shoe. A hanger can be optionally used. The liner is expanded into the enlarged diameter so that the net result is that the inside diameter in the wellbore is not reduced by the addition of the liner.
