Patent number: 8596356Abstract: Synthesis gas is more effectively produced from the underground gasification of coal from a coal seam when the casing lining is cemented with a cementitious slurry containing a cementitious material, graphite and an aluminum silicate, such as metakaolin. The cementitious slurry of the cement mix sets as a cement sheath at bottomhole static temperatures less than or equal to 65° C. The set cement may withstand extreme dry heat temperatures which are greater than or equal to 800° C.Type: GrantFiled: October 28, 2010Date of Patent: December 3, 2013Assignee: Baker Hughes IncorporatedInventors: Andreas Brandl, Dale R.

Patent number: 8592354Abstract: A method of cleaning a wellbore prior to the production of oil or gas is disclosed, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake. The method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid includes an aqueous fluid, a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting age, and where the hydrolysable ester is selected so that upon hydrolysis an organic acid is released and the invert emulsion of the filter cake breaks.Type: GrantFiled: December 22, 2011Date of Patent: November 26, 2013Assignee: M-I L.L.C.Inventors: Charles Svoboda, Raymond D. Ravitz, Mark Luyster
