Publication number: 20130255948Abstract: Well-cementing compositions for use in high-pressure, high-temperature (HPHT) wells are often densified, and contain weighting agents such as hematite, ilmenite, barite and hausmannite. The weighting agents are usually finely divided to help keep them suspended in the cement slurry. At high temperatures, finely divided weighting agents based on metal oxides react with the calcium-silicate-hydrate binder in set Portland, cement, leading to cement deterioration. Finely divided weighting agents based on metal sulfates are inert with respect to calcium silicate hydrate; consequently, set-cement stability is preserved.Type: ApplicationFiled: December 7, 2011Publication date: October 3, 2013Inventors: Michel Michaux, Laurent Gabilly

Publication number: 20130248183Abstract: Disclosed herein are cement compositions and methods of using set-delayed cement compositions in subterranean formations. A method of cementing in a subterranean formation, may comprise providing a set-delayed cement composition comprising water, pumice, hydrated lime, and a set retarder, activating the set-delayed cement composition with a cement set activator, wherein the cement set activator comprises at least one activator selected from the group consisting of nanosilica, a polyphosphate, and combinations thereof, introducing the set-delayed cement composition into a subterranean formation, and allowing the set-delayed cement composition to set in the subterranean formation.Type: ApplicationFiled: March 31, 2013Publication date: September 26, 2013Inventors: Thomas J. Pisklak, Kyriacos Agapiou, Pauline A. Otieno, Ronnie G. Morgan, Peter J. Boul, Lance E. Brothers
