Abstract: A downhole apparatus comprises a plurality of tubing sections. Each tubing section has substantially cylindrical end portions initially of a first diameter for coupling to end portions of adjacent tubing sections. The end portions are expandable to a larger second diameter. Each tubing section als o has an intermediate folded wall portions initially in a folded configuration . The intermediate folded wall portions are unfoldable to define a substantial ly cylindrical form of a third diameter.

Abstract: Embodiments of the present invention include methods and apparatus for dynamically controlling pressure within a wellbore while forming the wellbore. In one aspect, one or more pressure control apparatus are used to maintain desired pressure within the wellbore while drilling the wellbore. In another aspect, pressure is dynamically controlled while drilling using foam to maintain a substantially homogenous foam flow regime within the wellbore annulus for carrying cuttings from the wellbore.

Abstract: The present invention generally relates to an apparatus and method for expanding a tubular body in a wellbore. In one aspect, a method includes running the tubular body into the wellbore, the tubular body having a deformed portion. The method further includes reforming the deformed portion and positioning a two - position expander in the reformed portion. Additionally, the method includes shifting the expander to a second, larger diameter position and then expanding the reform ed portion by urging the expander therethrough. In another aspect, a method for completing a wellbore is provided. In yet another aspect, a formable launche r section is provided. In a further aspect, a two-position expander tool is provided. In yet another aspect, an expansion system for use in completing a wellbore is provided.

Abstract: The present invention relates methods and apparatus for lining a wellbore. In one aspect, a drilling assembly having an earth removal member and a wellbore lining conduit is manipulated to advance into the earth. The drilling assembly includes a first fluid flow path and a second fluid flow path. Fluid is flowed through the first fluid flow path, and at least a portion of which may return through the second fluid flow path. In one embodiment, the drilling assembly is provided with a third fluid flow path. After drilling has been completed, wellbore lining conduit may be cemented in the wellbore.

Abstract: The present invention provides a method and apparatus for deforming a tubular body, running the tubular body through a restriction in a wellbore, reforming the tubular body, and expanding at least a portion of the tubular body past its elastic limit. In one aspect, the present invention provides a method for forming a substantially monobore well involving deforming a tubular body, running the tubular body below a restricted inner diameter portion, reforming the tubular body, and expanding at least a portion of the tubular body past its elastic limit. The restricted inner diameter portion may comprise a casing string previously disposed within the wellbore or a casing patch. The at least the portion of the tubular body expanded past its elastic limit may be a lower portion of the tubular body. Subsequent tubular bodies may be reformed and expanded below previous tubular bodies.
