Patent number: 6664215Abstract: The disclosure is directed to a composition for controlling wellbore fluid and gas invasion including methods for using said composition. The composition of the invention is a flowable slurry preferably comprising about 70 to 30% by weight of magnesium oxychloride and about 70 to 30% by weight of water. The composition is a flowable slurry at composition temperatures below about 60° C. and sets to form a substantially solid mass upon reaching a composition temperature of about 60-68° C. The phase transition is rapid, thereby limiting or avoiding formation of gel states which contribute to incomplete wellbore seals. The rapid set of the slurry further avoids invasive contamination of earthen formations surrounding the wellbore. The composition has a near-linear relationship between the time required for the phase transition to occur and the composition temperature at which the phase transition occurs.Type: GrantFiled: June 6, 2000Date of Patent: December 16, 2003Inventor: Brian H. Tomlinson

Patent number: 5110361Abstract: Magnesium oxychloride cement compositions, products, and uses thereof, are provided by mixing magnesium oxide, a magnesium chloride solution, and aggregate particles. The cement compositions are adapted for use in repairing damaged concrete surfaces, casting both functional and decorative forms, and coating surfaces with stucco. The addition of a small amount of acid to the cement composition promotes a more complete cementing reaction. The resulting cement product exhibits substantially increased strength and water resistance. Brine from the Great Salt Lake is a preferable source of the magnesium chloride solution. Brine from the Great Salt Lake results in a cement composition substantially stronger than cement produced from a pure magnesium chloride solution. Use of the Great Salt Lake brine as the gauging solution in lieu of a gauging solution made from magnesium chloride flakes (hexahydrate) reduces manufacturing costs of magnesium oxychloride cement products.Type: GrantFiled: April 1, 1991Date of Patent: May 5, 1992Assignee: CAC, Inc.Inventors: Russell I. Alley, George E. Caine
