摘要： The present invention provides apparatus and methods for completing a wellbore using expandable tubulars. In one aspect, the invention includes a tubular member with an expandable portion at a lower end constructed and arranged to be expanded into contact with a previously expanded liner. At an upper end of the tubular is a polish bore receptacle permitting the tubular to be tied back to the surface of the well with production tubing. In another aspect, the invention provides a method of completing a well comprising expanding a liner top into a cased wellbore to hang the liner and, thereafter running a tubular member into the wellbore.

摘要： The present invention provides an expandable tubular having improved polished bore receptacle protection. The present invention further provides methods for completing a wellbore through the use of an expandable string of casing having improved polished bore receptacle protection. In one aspect, the invention includes a liner member having an expandable section, and a polished bore receptacle positioned below the expandable section. The expandable section is run into a wellbore, and is positioned to overlap with the bottom portion of a string of casing already set within the wellbore. The expandable section is then expanded into frictional engagement with the surrounding casing. The expandable section optionally includes at least one sealing member and at least one slip member on the outer surface. In one aspect, a transition section is provided between the expandable section and the polished bore receptacle. The transition section defines a sloped inner diameter which provides further protection for the sealing surfaces of the polished bore receptacle as tools, fluid, and tubulars are transited downhole through the polished bore receptacle.

摘要： The present invention provides apparatus and methods for expanding an expandable sand screen in the wellbore and then fracturing the wellbore. In one aspect of the invention, an expandable sand screen includes a perforated inner pipe and outer shroud. The outer shroud includes a plurality of longitudinal channels that retain their general shape after the expandable sand screen is expanded. In the expanded state, the channels provide a fluid conduit along an area between the screen and the wall of the wellbore. In a subsequent fracturing operation, slurry travels along the conduits permitting communication of the fracturing slurry with hydrocarbon bearing formations.

摘要： The present invention generally relates to controlling the flow of fluids in a wellbore. In one aspect, a valve for selectively closing a flow path through a wellbore in a first direction is provided. The valve includes a body and a piston surface formable across the flow path in the first direction. The piston surface is formed at an end of a shiftable member annularly disposed in the body. The valve further includes a flapper member, the flapper member closable to seal the flow path when the shiftable member moves from a first position to a second position due to fluid flow acting on the piston surface. In another aspect, a valve for selectively closing a flow path through a wellbore in a single direction is provided. In yet another aspect, a method for selectively closing a flow path through a wellbore in a first direction is provided.
