  • Storable nonaqueous cement slurries and methods of using same
    Patent number: 7575055
    Abstract: A method of servicing a wellbore comprising preparing a nonaqueous storable cementitious composition, mixing said composition with an aqueous fluid and, placing said composition into a wellbore. A method of cementing comprising preparing a mixture of cement, a suspension fluid, a dehydrating agent, a first surfactant, and a suspension aid, adding an aqueous solution and a second surfactant to said mixture and, placing the mixture downhole, and allowing the cement to set. A method of producing a lightweight cement slurry comprising the addition of a nonaqueous fluid to cement and water wherein the water content is less than about 40% by total weight of the composition. A method of servicing a wellbore comprising preparing a cement composition comprising from about 80% by weight cement suspended in a nonaqueous fluid, and stabilizing said cement composition through the addition of a suspension aid.
    Type: Grant

  • Cement compositions for reducing gas or water migration and methods of using the same
    Patent number: 7449062
    Abstract: A method of cementing a wellbore comprising preparing a cement composition comprising a water-soluble aromatic sulfonated polymer, and placing the cement composition into the wellbore, wherein the cement composition develops a compressive strength of greater than about zero in less time than a similar cement composition having a comparable thickening time and lacking a water-soluble aromatic sulfonated polymer. A cement composition comprising a water-soluble aromatic sulfonated polymer, wherein the cement composition develops a compressive strength of greater than about zero in less time than a similar cement composition having comparable thickening time and lacking a water-soluble aromatic sulfonated polymer.
