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 contains 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: The present disclosure relates to a low temperature, semi-continuous process for producing high purity rare earth metals and alloys in molten salts. Rare earth metals and alloys are reduced from the corresponding rare earth halide in molten salts in a semi-continuous process. An air stable pellet or ingot can be fed into molten salts and reduced through metallothermic reduction or electrolysis. The formation of an air stable feedstock minimizes handling concerns of the hygroscopic rare earth salts, allowing the reduction process to be run in a semi-continuous process. The process can optionally include the addition of alloying elements such as magnesium, iron and zinc reduce the required processing temperature.

Abstract: The use of degradable components 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 components that include one or more chemical additives that are released upon the partial or full dissolution of the degradable component, and which can be used to facilitate in the dissolution of the degradable component. The degradable component can optionally include tracer elements 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: A magnesium composite material and method for manufacturing a magnesium composite alloy wherein the magnesium composite alloy has improved thermal and mechanical properties. The improved thermal and mechanical properties are at least in part obtained by the modification of grain boundary properties in the magnesium composite alloy by the addition of nanoscale fillers to the magnesium composite alloy.

Abstract: A method for enhancing wellbore integrity and/or for sealing a wellbore by sealing formation or micro-annulus fractures in a wellbore. Such sealing can be at least partially accomplished by the use of timed expansion of an expandable sealant material that is placed a wellbore. The expansion of the expandable sealant material causes the cement surface or formation surface to be compressed, thereby creating a tight seal and/or eliminating annulus cracking, fracture, and/or gas channels in the wellbore. A degradable polymer can be used when restoration of the wellbore formation is desired.

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: A temporary well isolation device which has an axial passage that comprises a temporary housing having an internal cavity containing a chemical material and a temporary barrier or plug member that can be actuated by an external mechanism to allow fluid to flow into the internal chamber and contact the chemical material in the internal chamber. When the chemical material is exposed to fluid, the chemical material causes the temporary housing to corrode, dissolve, and/or degrade.
