    摘要： 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.

    摘要： 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.

    摘要： A modified high density brine for use in subterranean drilling and completion operations. The modified high density brine includes a heavy brine and the addition of high density particles. The resultant modified high density brine eliminates the need for toxic, corrosive, and costly ZrBr2 or cesium formate additions or other ionic additives to boost the density of the modified high density brine to more than 14 lbs./gallon.

    摘要： 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.
