  • METHOD FOR MAKING RESIN-COATED PROPPANTS AND A PROPPANT
    Publication number: 20120205101
    Abstract: A method for making resin-coated proppants comprising applying epoxy and phenol resins with a curing agent onto the surface of proppants. The epoxy and phenol resins with the curing agent are applied onto the surface of the mix of proppants. The mix of proppants is obtained by blending heavy proppants with bulk density of 1.4 g/cm3 and more, with lightweight proppants with bulk density of less than 1.4 g/cm3. The application of the epoxy and phenol resins is performed at temperatures from 5 to 35. degrees Celsius.

  • Precursor compositions for ceramic products
    Patent number: 7648934
    Abstract: A precursor composition for the production of granulated ceramic material to be used as hydraulic fracture proppant, comprises 20 to 55% pyroxene, and 15 to 50% olivine. The remaining component is quartz and/or feldspar. The precursor composition can be sintered in a broader temperature range. The resulting proppant material shows high mechanical strength and resistance to acids, and also higher stability under hydrothermal conditions than the prior art.

  • Ceramic proppant with low specific weight
    Patent number: 7521389
    Abstract: A precursor composition for the production of granulated ceramic material, particularly for ceramic proppants, comprises 20 to 55% by weight of magnesium orthosilicate, 20 to 35% by weight of MgO, and 2.5 to 11% by weight of Fe2O3. The resulting lightweight proppant material shows high mechanical strength. To further decrease the specific density of the proppant, the formation of small pores can be increased by adding 0.3 to 2.4% carbon as a gas-forming agent.
