    摘要： Methods for forming a portion of a wellbore are provided. The well is drilled from a first selected depth to a second selected depth to form a bore through a surrounding earth formation. A fluid heating apparatus is disposed within the bore on a working string. Fluid is then heated by moving the fluid through the fluid heating apparatus in the wellbore. The process of circulating fluid adjacent the earth formation serves to also heat the surrounding formation so as to increase the fracture gradient. The fluid heating process may be conducted during a drilling procedure. Alternatively, the fluid heating process may be conducted in connection with a liner hanging and cementing process. A fluid flow restrictor is provided along a run-in assembly that serves to warm the fluids as they are circulated. The warm fluids provide convective heat to the surrounding earth formation, thereby reducing the formation's fracture gradient.

    摘要： The present invention generally relates to an apparatus for sealing a wellbore. The sealing apparatus includes an expandable tubular body having one or more sealing elements disposed thereon. In one aspect, the sealing elements include swelling and non-swelling sealing elements. Preferably, the swelling sealing elements are made of a swelling elastomer capable of swelling upon activation by an activating agent. The swelling elements may be covered with a protective layer during the run-in. When the tubular body is expanded, the protective layer breaks, thereby exposing the swelling elements to the activating agent. In turn, the swelling elements swell and contact the wellbore to form a fluid tight seal.

    摘要： The present invention relates to a method and apparatus for anchoring an expandable tubular within a wellbore prior to expanding the length of the expandable tubular into contact with the wellbore. An expandable system comprises the expandable tubular and a deployment tool, wherein the deployment tool exerts radial force against the expandable tubular to expand at least a portion of the expandable tubular into contact with the wellbore to anchor the expandable tubular prior to the expansion process. A method for anchoring an expandable tubular within a wellbore prior to the expansion process is also provided, wherein radial force expands the expandable tubular into contact with the wellbore to initially anchor the expandable tubular. A method for altering the shape of the anchor is also provided.

    摘要： The present invention relates to packers adapted to seal an annular space within a wellbore. The packers, for example, may be utilized to circulate or reverse circulate a fluid. In one embodiment, the present apparatus comprises a first tubular subunit and a second tubular subunit moveably coupled together, a flexible packing element disposed between the first tubular subunit and the second tubular subunit, and a temporary mechanical connection adapted to restrain the first tubular subunit and the second tubular subunit from compressing the flexible packing element, in which the temporary mechanical connection is adapted to be hydraulically disengaged. In another embodiment, the present apparatus further comprises a valve. The valve may be selectively opened to allow fluid to flow between the annular space and the central bore of the valve.
