Abstract: The present invention provides an expandable tubular having improved polishe d bore receptacle protection. The present invention further provides methods f or completing a wellbore through the use of an expandable string of casing havi ng improved polished bore receptacle protection. In one aspect, the invention includes a liner member (200) having an expandable section (225), and a polished bore receptacle (25) positioned below the expandable section. The expandable section is run into a wellbore (205), and is positioned to overla p with the bottom portion of a string of casing (210) 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 (260) and at least one slip member (270) on the out er surface. In one aspect, a transition section (275) 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 tubula rs are transited downhole through the polished bore receptacle.

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 path. After drilling has been completed, wellbore lining conduit may be cemented in the wellbore.

Abstract: A tubular configured to mate with a second tubular so that sealing integrity is maintained between the tubulars before, during, and after expansion of the tubulars is disclosed. In one embodiment, a connector for connecting tubulars is provided. The connector includes a pin portion; a box portion, wherein the pin and the box portions are configured to mate; a sealing surface formed in an inner surface of the box portion; a seal disposed in a groove formed in an outer surface of the pin portion, wherein the seal is configured to engage with a sealing surface of the box portion upon mating of the pin and the box portions; and a bump formed on an inner surface of the pin portion, wherein the bump is substantially radially aligned with the groove and the bump is configured so that the seal remains engaged with the box portion during and after expansion of the pin and the box portions.

Abstract: The present invention provides an apparatus and method expanding a portion of a tubular. The expansion apparatus is run into a wellbore on a working string. The expansion apparatus first comprises a rotary expander for expanding an expandable tubular. The expansion apparatus further comprises a spline assembly for coupling the rotary expander to a motor disposed on the work string. The rotary expander and spline assembly have hollow bodies that allow them to encircle the work string and rotate relative thereto. The spline assembly comprises an inner sleeve and outer sleeve. The inner sleeve is attached to the motor and the outer sleeve is attached to the rotary expander. The inner and outer sleeves are coupled to each other using a spline and groove connection. The connection allows the rotary expander to be rotated by the motor, while at the same time, allow the rotary expander to move axially relative to the motor. The rotary expander comprises two rows of rollers for expansion against the tubular. The position of the rollers on the first row is skewed in one direction relative to the longitudinal axis. The rollers on the second row are skewed in an opposite direction. When actuated, the skew angle of the rollers will cause the expander tool to move axially. Because the rollers of the two rows are placed at opposing skew angles, alternating actuation between the two rows of rollers causes the expander to move in opposite axial directions during expansion.
