  • Lightweight hollow particles for use in cementing
    Patent number: 9765253
    Abstract: A lightweight composite having an activated surface contains a lightweight hollow core particle having cement grains which may be adhered to the hollow core or embedded in the surface of the hollow core. The hollow core particle may be prepared from calcium carbonate and a mixture of clay, such as bentonite, and a glassy inorganic material, such as glass spheres, glass beads, glass bubbles, borosilicate glass and fiberglass.
    Type: Grant
    Filed: May 15, 2015
    Date of Patent: September 19, 2017
    Assignee: Baker Hughes, a GE company, LLC

  • Light-weight proppant from heat-treated pumice
    Patent number: 8796188
    Abstract: A process for forming a strong, low-density proppant, which process includes heating pumice particulates, or shaped agglomerates thereof, so as to form heat-treated pumice particulates, or heat-treated, shaped pumice agglomerates, having an apparent density of 2.4 or less and a crush resistance of no more than 10% fines at 4000 psi. Proppants, and well treatment fluids comprising proppants, meeting these characteristics and processes for treating subterranean formations using fluids which include such proppants are also described.
