Abstract: An apparatus for expanding a tubular member comprising a support member, an expansion device for radially expanding the tubular member movably coupled to the support member for longitudinal displacement relative to the support member, at least one pressure chamber defined by and positioned between the support member and expansion device, and one or more releasable supports coupled to the support member adapted to support the tubular member, wherein the releasable supports are positioned above the expansion device.

Abstract: A mono-diameter wellbore casing is formed by radially expanding a first tubular liner off of a mandrel into contact with a second tubular liner. The first and second tubular liners are positioned within the wellbore in an overlapping relationship. The overlapping portions of the tubular liners include thin wall portions with compressible annular members that are expanded into contact with each other.

Abstract: A mono-diameter wellbore casing. The mono-diameter wellbore casing is formed by plastically deforming and radially expanding a first tubular member within a wellbore. A second tubular member is then plastically deformed and radially expanded in overlapping relation to the first tubular member. The second tubular member and the overlapping portion of the first tubular member are then radially expanded again.

Abstract: An apparatus and method for in-situ milling includes a support and a pair of spaced apart rails attached to the support. The support and rails are mounted between a pair of opposed mill housing wear plate surfaces. A milling assembly is reversibly mounted on the rails in either of a first orientation and a second orientation. In the first orientation, the milling assembly mills one of the wear plate surfaces. The milling assembly is reverse mounted on the rails to the second orientation for milling the other of the wear plate surfaces. This permits the support and the rails to remain in one position between the wear plate surfaces requiring only the milling assembly to be moved to accomplish milling of each of the wear plate surfaces.

Abstract: A wellhead is formed by extruding a plurality of tubular liners off of a mandrel into contact with an outer casing. The first tubular liner and mandrel are positioned within the wellbore with the tubular liner in an overlapping relationship with the outer casing. At least a portion of the tubular liner is extruded off of the mandrel into contact with the interior surface of the outer casing. The first tubular liner is extruded off of the mandrel by pressurizing an interior portion of the first tubular liner. Subsequent tubular liners are positioned in concentric overlapping relation and similarly extruded off of a mandrel into at least partial contact with the interior surface of the outer casing.

Abstract: An air purification apparatus is disclosed that includes a HEPA or ULPA cartridge filter having mounted axially therein an UV lamp extending from a closed end of the cartridge. An air channeling housing is provided for removably mounting the combination filter and lamp assembly for ingress of an air stream through the open end of the combination filter and lamp assembly and for egress of the air stream through the filter medium. A fan can be mounted in the housing either upstream or downstream of the combination filter to provide the means for flowing air through the housing for decontamination by both the filter and UV irradiation provided by the combination filter and lamp assembly. With this arrangement, all contaminants trapped on the filter are within the combination filter and lamp assembly for constant illumination by the UV lamp to destroy bacteria both in the incoming air stream and while resident on the interior of the filter assembly.

Abstract: A wellbore casing is formed simultaneously with the drilling out of the wellbore.

Abstract: A system, method, and computer program is disclosed for managing integrated real-time information about air flight trips, providing that information to multiple users, and receiving feedback from multiple users. A plurality of user interfaces are provided for displaying a plurality of types of information about a real time progress air trips as planned by an operational center. A communication channel is provided for receiving feedback information from the users and associating that feedback with a particular aspect of the trip.

Abstract: One or more subterranean zones are isolated from one or more other subterranean zones using a combination of solid tubulars and perforated tubulars.

Abstract: An apparatus and method for forming a wellbore casing. An annular piston is displaced in the axial direction by pressurizing an annular piston chamber. The axial displacement of the piston radially expands a tubular member into contact with a preexisting tubular member. The radially expanded liner hanger is then decoupled from the apparatus.

Abstract: A lubricant coating (240) for expandable tubulars (215). The interior surfaces of the expandable tubulars are coated with the lubricant coating (240). The expandable tubulars (215) are then placed within a preexisting structure (205). The expandable tubulars are then radially expanded into contact with the preexisting structure.
