Abstract: Slip members for use with downhole tools comprise a body formed of a first or body material and one or more hard material elements formed of a second or element material. The element material is harder than the body material. The hard material element is disposed through the body and in communication with a first surface and a second surface of the body, the second surface being disposed opposing the first surface. During manufacturing of the slip members, the hard material element may extend outwardly from one or both of the first and second surfaces. After manufacturing, the hard material element can be shaped to provide a gripping member.

Abstract: A spring for use in downhole tools delivers a high force over a long deflection in a relatively uniform fashion. The spring is a tubular shape that is preferably metallic and is preferably plastically deformed into an undulating walled tube either before assembly into a downhole tool or downhole after assembly to the downhole tool. Alternatively the shape can be machined. Spacer rings are used inside and outside the tube as it is compressed to obtain the desired corrugated wall pattern and to prevent localized buckling that can cause wall failure. The spring can conduct pressurized fluids and be rotationally locked to transmit torque and to facilitate milling out. Some machining internally and/or externally can assist in forming the desired corrugated wall shape.

Abstract: Sealing devices for use in a wellbore to seal a leak path through an inner wall surface of the wellbore comprise a mandrel, an expandable element, and a shape deforming sealing element. Expansion or inflation of the expandable element moves the shape deforming sealing element from its run-in shape to its set shape. A stimulus, such as a change in temperature, acts upon the shape deforming sealing element facilitating the shape deforming sealing element changing shape. Removal of the stimulus causes the shape deforming sealing element to remain in the set shape. Thereafter, the mandrel and expandable element can be removed to leave only the shape deforming sealing element within the wellbore to seal the leak path.

Abstract: A modular screen system allows connection of screens using couplings that connect the annular space in each module between the screen material and the base pipe. A series of connected screens and couplings feed into a single valve to control the flow through many screens. The valve is preferably located in a coupling and the passages through the coupling or the screen can also accommodate instrumentation to detect, store or transmit well data or flows through the various screen modules.

Abstract: A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. A moveable cover is disposed interior to the slip thereby restricting movement of the slip from a unset position to a set position. The liner hanger housing is secured in the string of casing and an actuator is mounted on the liner. As the liner is moved through the casing coupler, the actuator actuates the cover, causing the cover to be moved so that the slip can move axially downward from its unset position to its set position. As the cover is moved, the slip moves radially inward and grips the liner to secure the liner within the casing string of the wellbore.

Abstract: A space filler material is used to prevent accumulation of debris that could later foul the operation of adjacent moving parts. In one application a void space that is subsequently closed by actuated parts is initially filled with a material that is highly compressible and has voids that allow it to compress without undue resistance to part movement when the void volume is reduced. Ideally, the pores or voids in the material itself are small enough to keep most if not all the debris from entering and making the space filling material too rigid to collapse under part movement. In an alternative application, the material can be in an annular space such as a seal bore and it can keep debris from getting past the seal bore while allowing hydrostatic pressure across itself thereby helping it to maintain its position until moved such as by shifting of an inner string to which it is attached.

Abstract: Nanoparticle-treated substrates, such as screens, sand beds or proppant beds, may effectively filter and purify fluids such as waste water or fluids produced from a formation, as well as other liquids. When tiny contaminant particles in a fluid such as waste water flow contact the nanoparticle-treated substrate, the nanoparticles will capture and hold the tiny contaminant particles on the substrate due to the nanoparticles' surface forces, including, but not necessarily limited to van der Waals and electrostatic forces or other associative forces. Coating agents such as alcohols, glycols, polyols, vegetable oil, and mineral oils may help apply the nanoparticles to the surfaces of structures in the filter beds or packs.
