  • Apparatus for manufacturing ceramic microspheres for cementing applications
    Patent number: 8291727
    Abstract: A method and apparatus for manufacturing ceramic microspheres from industrial slag. The microspheres have a particle size of about 38 microns to about 150 microns. The microspheres are used to create a cement slurry having a density of at least about 11 lbs/g. The resultant cement slurry may then be used to treat subterranean wells.
    Type: Grant
    Filed: December 17, 2010
    Date of Patent: October 23, 2012
    Assignee: Intevep, S.A.
    Inventors: George Quercia, Yibran Perera, Aiskely Blanco, Fedymar Pereira
