    摘要： An apparatus protects 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 with the mounting location on the casing. After expansion the liner can be cemented. A shifting tool can be run on the expansion string to actuate the sliding sleeve and if necessary to allow for cement to be pumped from the drill string into the annulus through the sliding sleeve.

    摘要： Radially expanding a tubular such as a liner or casing, especially in a downward direction. The apparatus includes at least one driver device such as a piston that is typically fluid-actuated, and an expander device is attached to the or each driver device. Actuation of the or each driver device causes movement of the expander device to expand the tubular. One or more anchoring devices, which may be radially offset, are used to substantially prevent the tubular from moving during expansion thereof.

    摘要： A mono-diameter wellbore casing. A tubular liner and an expansion cone are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with a pre-existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the expansion cone and into the annular region between the tubular liner and the new section of the wellbore. The inner and outer regions of the tubular liner are then fluidicly isolated. A non hardenable fluidic material is then injected into a portion of an interior region of the tubular liner to pressurize the portion of the interior region of the tubular liner below the expansion cone. The tubular liner is then extruded off of the expansion cone. The overlapping portion of the pre-existing casing and the tubular liner are then radially expanded using an expansion cone.

    摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.
