  • Patent number: 8852682
    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.
    Type: Grant
    Filed: October 18, 2006
    Date of Patent: October 7, 2014

  • Patent number: 7647964
    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.

  • Patent number: 7490667
    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.

  • Patent number: 7244492
    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.

  • Publication number: 20020058581
    Abstract: An aluminosilicate ceramic, spherical pellet made from spent ceramic catalyst. More specifically, a spherical ceramic pellet made from spent fluid cracking catalyst. The pellets can be made by grinding the catalyst particles, forming them into spherical pellets, and then sintering the pellets. The final product is useful as a proppant in oil and gas well fracturing.
