  • Method of selecting a wellbore cement having desirable characteristics
    Patent number: 7792250
    Abstract: A method for determining the ability of a cement composition to withstand subterranean formation conditions comprising obtaining an experimental diffraction pattern of the cement composition, generating a theoretical diffraction pattern of the cement composition, comparing the experimental diffraction pattern with the theoretical diffraction pattern, refining the theoretical diffraction pattern using a structural refinement method, determining the relative fraction of the crystalline phases present in the cement composition from the theoretical diffraction pattern, and determining the ability of the cement composition to withstand subterranean formation conditions.

  • Testing mechanical properties
    Patent number: 7621186
    Abstract: Cement is conditioned, cured and/or tested while applying a specified temperature and/or pressure. In certain embodiments, the specified temperature and/or pressure applied during the testing substantially simulates anticipated static downhole conditions the cement will be subjected to in use. In certain embodiments, the specified temperature and/or pressure applied during the receiving substantially simulates pumping placement conditions the cement will be subjected to in use. In certain embodiments, the cement can be conditioned in a conditioning vessel while applying specified temperature and/or pressure to the cement. In certain embodiments, the temperature and/or pressure applied in the conditioning substantially simulates anticipated pumping placement conditions the cement will be subjected to in use.
