Abstract: An apparatus and method of creating a seal between two coaxial tubulars so as to create a hanger and a packer. A first tubular (200) is disposed coaxially within a portion of a second, larger tubular (400). A portion of the first tubular is expanded into frictional contact with the second tubular, thereby creating a liner and a hanger. In one embodiment, a pattern of grooves (210) and profile cuts (205) is formed in the surface of a portion of the first tubular body. The grooves and profile cuts in one aspect define a continuous pattern about the circumference of the tubular body which intersect to form a plurality of substantially identical shapes, such as diamonds. The grooves and profile cuts serve to improve the tensile strength of the tubular body. At the same time, the grooves and profile cuts allow for expansion of the tubular body by use of less radial force. The grooves and profile cuts further provide a gripping means, providing additional frictional support for hanging the expanded tubular onto the inner surface of a surrounding second tubular. Carbide inserts (220) are preferably interdisposed within the pattern of grooves, providing additional gripping means when the smaller diameter tubular body is expanded into the second tubular.

Abstract: The present invention provides a roller sub for use downhole in oil or gas wells as part of a toolstring or drill string to reduce friction between the string and wellbore. The roller sub is a modular assembly of parts which assemble together to trap the roller wheels in place between them, avoiding need for grub screws to fasten the individual wheels and rendering the roller sub very compact.

Abstract: An artificial lift system used to produce fluids from boreholes such as oil and gas wells. The system uses a progressive cavity (PC) downhole pump system (100) which can be inserted into the borehole, seated, operated, flushed and removed using conventional or coiled sucker rod tubing. No special tubing is required to radially anchor the PC pump to the tubing. The PC pump system has improved flushing capabilities which reduces the length of the system. The system is less costly to manufacture and to maintain than prior art PC pump systems. The pump can be relocated without pulling tubing. Different displacement volumes and lifts can be substituted in existing installations without major changes to equipment installed in the tubing string.

Abstract: A screen material having a flexible member is disclosed. The screen material (10) includes closely spaced filter wires (14) supported by a plurality of support members (12). A stranded cable (12) is used as the support member to provide flexibility to the screen material. The filter wires are welded to the members and define filter gaps (24) between adjacent filter wires to allow liquid and small particles to pass through, while retaining particles too large to fit through the filter gaps.

Abstract: The present invention provides an apparatus and method for severing casing as it is pulled from a wellbore. An apparatus (100) is provided, comprising a clamping assembly (130), a drilling assembly (150) and a cutting assembly (120). In one aspect, the apparatus is disposed at the end of a telescopic arm (110), with the components being remotely operated by personnel using a control panel (125). The apparatus can be positioned adjacent casing (200') and clamped thereto. Thereafter, the apparatus can drill a hole completely through the casing for the insertion of a retention pin. The apparatus can then severe the casing into manageable lengths to facilitate disposal, such as during a plugging and abandonment procedure.
