Abstract: A castable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contain an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

Abstract: Expandable tube members that are fabricated from a composite material that includes a structural plastic, which structural plastic includes phase change materials that undergo a permanent expansion upon exposure to wellbore conditions. This permanent expansion of the structural plastic causes the expandable tube member to expand radially and/or longitudinally without the use of an expansion tool. The expandable tube member can be used to control fluid loss, patch wells, stabilize a formation in a wellbore, enhance flow, provide sand screening, and repair damaged pipes, casings, or liners.

Abstract: A degradable elastomeric material that is formed from a composite blend of elastomeric particles in a continuous degradable binder. The degradable binder is generally a water-soluble binder which has a temperature dependent solubility in water and brine systems. Such degradable elastomers are particularly useful in the fabrication of degradable oil tools, among other applications.

Abstract: A high strength engineered reactive composite that includes a reactive core. These reactive composites are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties.

Abstract: An engineered composite system designed to be passive or inert under one set of conditions, but becomes active when exposed to a second set of conditions. This system can include a dissolving or disintegrating core, and a surface coating that has higher strength or which only dissolves under certain temperature and pH conditions, or in selected fluids. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties, but which can be stored and used for long periods of time without degradation.

Abstract: The use of degradable or dissolvable tools has become a more common practice in subterranean operations for such applications as temporarily isolating zones or diverting flow. A major concern of operators in using degradable tools is the ability to ensure that the tool has completely degraded and is no longer blocking or obstructing flow. This issue can be resolved through the use of degradable or dissolving tools and devices that include one or more tracer elements (e.g., tracer chemicals, chemical elements, particles, tags [RFID, physical tag, microdevice, etc.], etc.) that are released upon the partial or full dissolution of the degradable component, and which can be detected at the surface to ensure the desired degradation or removal of the degradable component as well as hydraulic access to that stage.

Abstract: The invention is directed to the interventionless activation of wellbore devices using dissolving and/or degrading and/or expanding structural materials. Engineered response materials, such as those that dissolve and/or degrade or expand upon exposure to specific environment, can be used to centralize a device in a wellbore.

Abstract: A high density, generally recognized as safe hybrid rocket motor is described which has a density-specific impulse similar to a solid rocket motor, with good performance approaching or equal to a liquid rocket motor. These high density hybrid motors resolve the packaging efficiency/effectiveness problems limiting the application of safe, low cost hybrid motor technology.
