Abstract: Methods for cost effectively transforming lower quality silica sands into higher quality silica sands for use as proppants in fracking operations involving subterranean hydrocarbon formations. A process of exposing silica sand proppants to locally-sourced electromagnetic radiation, and systems therefor, are disclosed and shown to increase the performance of those silica sands as proppants in hydrocarbon formation fracturing operations.

Abstract: Methods for cost effectively transforming lower quality silica sands into higher quality silica sands having increased crush resistance for use as proppants in fracturing operations involving subterranean hydrocarbon formations. One or more of an attrition process, a microwaving process and a tumbling process are disclosed and shown to be applied to silica sands having inferior physical properties in order to increase the performance of those silica sands as proppants in hydrocarbon formation fracturing operations.

Abstract: A meta crosslinked polar benzyl polymer is made by combining a transition metal crosslinker, or one or more source compounds capable of reacting to form such a transition metal crosslinker, with a polar benzyl polymer which has been activated for meta crosslinking.

Abstract: A high strength composite particle comprised of a series of incrementally applied resin microlayer coatings such that each of the microlayer partial coatings are interleaved with each other is described. Methods of making the composite particles, as well as methods of using such particles as a proppant in oil and gas well hydraulic fracturing are also described.

Abstract: Described is an oil-degradable ball sealer for use in the oil and gas industry. The ball seal comprises a particular composition including ethylene and one or more alpha-olefins, prepared by an injection molding technique to provide a ball sealer which will dissolve in stimulation or wellbore fluids after stimulation operations are complete. The composition, when dissolved into wellbore fluids, does not pose a hazard or problem to aqueous wellbore fluids or further wellbore stimulations.

Abstract: A new proppant comprises a proppant particle substrate, a water-soluble external coating on the proppant particle substrate and a microparticulate reinforcing and spacing agent at least partially embedded in the water-soluble external coating in a manner such that the microparticulate reinforcing agent is substantially released from the proppant particle substrate when the water-soluble coating dissolves or degrades.

Abstract: Coated particle substrates having a coating of resin and/or water soluble polymers and soluble, fibrous material are provided for use in subterranean formations. The coated particle substrate particles are typically proppants used to prop open subterranean hydrocarbon formations during recovery processes, such as after a hydraulic fracture, and provide both improved settling characteristics and improved hydrocarbon flow characteristics due to the conductive channels formed by the soluble fibers downhole. Methods of making the coated particles are also described.

Abstract: Methods and compositions for stimulating single and multiple intervals in subterranean wells by diverting well treatment fluids into a particular direction or into multiple intervals using water soluble coated diverting agents are described. The water soluble coating of the diverting material is preferably a collagen, poly(alkylene) oxide, poly(lactic acid), polyvinylacetate, polyvinylalcohol, polyvinylacetate/polyvinylalcohol polymer or a mixture thereof applied as a coating on any number of proppants. The method allows for the diverting of the flow of fluids in a downhole formation during a well treatment, such as during a fracturing process. Following completion of a treatment such as a hydraulic stimulation, the soluble diverting agent can be dissolved and removed by the water component of the well production.

Abstract: Coated composite proppant particles made of particulate substrates having an elastomeric coating are provided for use in reducing particulate flowback in subterranean formations. The disclosed proppant particles can have a coating of resin, fibrous materials, and/or soluble resin coatings in addition to an elastomeric coating. Methods of making the coated particles are also described, as well as their use in subterranean formations.
