  • Patent number: 7861790
    Abstract: 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.

  • Patent number: 7032679
    Abstract: 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.

  • Patent number: 6997264
    Abstract: A connector arrangement used for connecting a first tubular to a second tubular. The first tubular member has at least one circumferential ring profile, and the second tubular member has a corresponding number of matching circumferential ring profiles. When the ring profiles of the two tubulars are mated and interlocked, they form separate and independent fluid seals as well as a mechanical lock able to hold the tubulars together during future expansion of the entire tubular and joint. Further, selecting properties of the tubulars such as yield strength and modulus of elasticity or constraining a diameter of one of the tubulars during expansion or compression forms a tight connection due to elastic recovery of the tubulars.

  • Patent number: 6868905
    Abstract: 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.
