Abstract: An apparatus and method for completing an interval of a wellbore while drilling comprises a drill string (52) having a drill bit (30) mounted on the lower end thereof. A completion assembly (50) is positioned around a section of the drill string (52) such that when the wellbore (32) is extended by rotating the drill bit (30) and advancing the drill string (52), the completion assembly (50) does not rotate. The advancement of the drill string (52) and rotation of the drill bit (30) is ceased when the completion assembly (50) has reached the desired interval of the wellbore (32). Thereafter, the drill string (52) is disconnected from the drill bit (30) for retrieval to the surface leaving the completion assembly (50) and the drill bit (30) downhole.

Abstract: A well completion system for reducing the pressure drop in fluids produced from a downhole formation (14) traversed by a wellbore (32) comprises a production tubing (30) used to bring the formation fluids to the surface that is positioned within a well casing (34) that lines the wellbore (32). An expander member (56) is positioned within the production tubing (30) and travels longitudinally within the production tubing (30) to expand the flow area within the production tubing (30) once the production tubing (30) has been installed downhole, thereby reducing the pressure drop in fluids produced through the production tubing (30).

Abstract: An internal support apparatus and method for providing support to a tubular structure that is positioned in a wellbore. The apparatus is insertable into the tubular structure to reside in close proximity with an interior surface of the tubular structure, make light contact with an interior surface of the tubular structure, or expand the tubular structure. Thereafter, the support apparatus can remain in the tubular structure indefinitely to provide support against collapse or further collapse and allow the tubular structure to remain in operation.

Abstract: Apparatus and methods for completing a wellbore are disclosed. Certain ones of the apparatus and methods use a first packing assembly, a second packing assembly, and a pressurization assembly disposed between the first and second packing assemblies to plastically deform a liner in a radially outward direction via hydraulic pressure. Another method uses a liner having a first section and a second section, and a packing assembly. The first section is deformable in a radially outward direction at a lower pressure than the second section. The packing assembly is used to plastically deform the first section of the liner in a radially outward direction via hydraulic pressure.
