  • Permeable cements
    Patent number: 7717176
    Abstract: A permeable cement composition including an aqueous slurry of a hydraulic cement which is based upon a water-immiscible dispersed fluid phase and a hollow particulate material. The hollow particulate material breaks down in the presence of the cement so as to leave voids which together with the dispersed phase create a permeable structure in the cement.
    Type: Grant
    Filed: April 20, 2006
    Date of Patent: May 18, 2010
    Assignee: Schlumberger Technology Corporation
    Inventors: Samuel Danican, Bruno Drochon, Simon James, Beilin Ding
  • Chemical Activation for Cement Setting
    Publication number: 20090194283
    Abstract: The present invention relates to a method of accelerating the compressive strength development and setting time of a cement slurry during a cementing operation for a wellbore. The method generally comprises the steps of preparing a cement slurry comprising a hydraulic cement and water at the surface; placing the cement slurry in the wellbore; adding an activator to the cement slurry in the wellbore; and allowing the cement composition to set, wherein the activator acts as a set accelerating agent and a compressive strength enhancing additive.

  • Permeable cements
    Patent number: 7063738
    Abstract: A permeable cement composition comprises an aqueous slurry of a hydraulic cement including a water-immiscible dispersed fluid phase, such as oil or gas, and a hollow particulate material, the hollow particulate material being one which breaks down in the presence of the cement so as to leave voids which together with the dispersed phase create a permeable structure in the cement.
