Patent number: 8434552Abstract: Compositions containing an alkali swelling polymer and a pH buffer with a pH between 3 and 7 may be used to treat a wellbore. The pH buffer prevents the swelling of the alkali swellable polymer. The compositions may be placed in the wellbore, whereupon they contact another material with pH increasing properties. The pH of the compositions increases, causing the compositions to swell and form a seal. The alkali swelling polymer may be an alkali swelling latex.Type: GrantFiled: December 11, 2008Date of Patent: May 7, 2013Assignee: Schlumberger Technology CorporationInventors: Bruno Drochon, Simon James, Sylvaine Le Roy-Delage, Clara Carelli

Publication number: 20130105161Abstract: A method includes providing a cementing composition that includes an aqueous fluid, a cementitious particulate, and a copolymer particulate which includes a monofunctional monomer, a water degradable first crosslinker, and a second crosslinker. The method further includes placing the cementing composition in a subterranean formation so as to form a set cement sheath and swelling the copolymer particulate in response to a void created in the set cement sheath. The copolymer particulate allows the cementing composition to set to form the cement sheath before substantial swelling of the copolymer particulate occurs.Type: ApplicationFiled: October 27, 2011Publication date: May 2, 2013Applicant: Halliburton Energy Services, Inc.Inventors: Gary P.

Publication number: 20130062062Abstract: A system and method for extending a slotted liner shoe is disclosed. According to one embodiment, a low density material is injected into a liner having a plurality of openings. The liner is suspended below a cemented casing in a wellbore of a well in a subterranean formation. The low density material extrudes through a lower portion of the liner into an annulus between the liner and the wellbore. A cement is circulated into the liner above the low density material. The cement extrudes through an upper portion of the liner into the annulus between the liner and the wellbore Water is displaced from the wellbore, and a solid cemented casing string is formed at a desired depth.Type: ApplicationFiled: September 10, 2012Publication date: March 14, 2013Applicant: AltaRock Energy, Inc.Inventors: Susan Petty, Daniel L.
