  • Sintered spherical pellets containing clay as a major component useful for gas and oil well proppants
    Patent number: 4879181
    Abstract: Sintered, spherical composite pellets or particles comprising one or more clays as a major component and bauxite, alumina, or mixtures thereof, are described, along with the process for their manufacture. The pellets may have an alumina-silica (Al.sub.2 O.sub.3 --SiO.sub.2) ratio from about 9:1 to about 1:1 by weight. The use of such pellets in hydraulic fracturing of subterranean formations is also described.

  • Use of uncalcined/partially calcined ingredients in the manufacture of sintered pellets useful for gas and oil well proppants
    Patent number: 4658899
    Abstract: A composite, sintered, spherical pellet and a method for its manufacture are described. The pellet is prepared from at least one uncalcined or partially calcined ingredient selected from the group consisting of clay and bauxite materials, dust collector fines and alumina. The pellet may have an alumina-to-silica ratio from about 9:1 to about 1:1. The pellet has a specific gravity of less than 3.40. Use of such pellets in propping hydraulically fractured subterranean formations is also described.
