Abstract: A composite particle that incorporates a material and is designed to undergo a reaction and/or mechanical or chemical change with the environment to increase in volume. The composite particle can be combined with a constraining matrix to create an expandable particle upon reaction. These particles can be used in stimulating wells, including oil and gas reservoirs.

Abstract: A cross-linkable thermoplastic resin coating that is suitable for use in a coated proppant material used in sand control in oil and gas wells. The cross-linkable thermoplastic exhibits improved stability and low temperature and pressure strength compared to current thermo setting resin formulations. The present invention relates to thermoplastic-coated particles and to methods of preparing thermoplastic-coated particles for subterranean operations such as gravel packing, frac-packing, and hydraulic fracturing. The application of thermoplastic coatings on the particles is suited for low temperature wells, wherein thermoset curable resins perform poorly.

Abstract: A non-linear surfactant, and particularly a non-linear surfactant comprising bi-functionalized molecules or particles having both hydrophobic and hydrophilic groups. The non-linear surfactant includes a nanoparticle template of a rigid molecular structure, wherein the nanoparticle comprises a molecule or a particle that is bi-functionalized with both hydrophilic and hydrophobic groups to obtain an amphiphilic nanoparticle. The template nanoparticle can be used as a surfactant, wetting agent, emulsifier, detergent or other surface-active agents or for the preparation of nanoemulsions or dispersions. The non-linear surfactant can provide smaller particle sizes for emulsion suspensions and foams.

Abstract: A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.
