  • Cement retarder and method of using the same
    Patent number: 9410072
    Abstract: The reaction product of a polyhydroxy compound and borax is used as a cement retarder for slurries introduced into a wellbore. The molar ratio of the polyhydroxy compound to boron, derived from the borax, is from 1:1 to about 4:1. The polyhydroxy compound may be a sugar such as a gluconic acid, gluconate or glucoheptonate or a salt thereof.
    Type: Grant
    Filed: June 29, 2011

  • Method of increasing lubricity of brine-based drilling fluids and completion brines
    Patent number: 8071510
    Abstract: The lubricity of a drilling fluid or a completion fluid may be increased by incorporating into the fluid a water-soluble or water-dispersible salt of a sulfonated (sulfated) vegetable oil or a derivative thereof, such as a sulfonated (sulfated) castor oil. Suitable derivatives include the sodium, potassium, calcium, magnesium or ammonium salt. A non-ionic or anionic surfactant which is capable of enhancing the solubility of the salt may further be incorporated into the drilling fluid or completion fluid.
