Patent number: 7795187Abstract: A method for plugging a permeable zone or leak in a subterranean formation comprises introducing into the formation a cross-linkable organic polymer and a cross-linking composition which comprises a zirconium triethanolamine complex, a tetra(hydroxyalkyl)ethylenediamine, water and optionally, a polyol. The method can be used for cross-linking organic polymers over a wide range of pH. By varying the composition and optionally adding a delay agent, the method provides flexibility in rate of cross-linking.Type: GrantFiled: February 14, 2006Date of Patent: September 14, 2010Inventor: Donald Edward Putzig

Publication number: 20100197530Abstract: The present disclosure is directed to a method comprising introducing into a well bore a fluid comprising a zwitterionic polymer. The polymer is prepared by inverse emulsion polymerization of at least one monomer Ab comprising a betaine group and optionally one or more nonionic monomers Ba. The well bore is chosen from a natural gas well bore and an oil well bore.Type: ApplicationFiled: February 4, 2009Publication date: August 5, 2010Inventors: D.V.

Publication number: 20100137170Abstract: Stabilized sulfide control compositions for oil well and related uses are provided which include a first ingredient selected from the group consisting of tetra (hydroxymethyl) phosphine (THP) or a salt thereof (THPS) and an amino phosophono chelant. The compositions are stabilized against cold-weather crystal formation and deposition by the presence of a morpholine-based stabilizing agent. Preferred compositions include the sulfate salt of THP, diethylenetriamine penta (methylenephosophonic acid) sodium salt, and morpholine.Type: ApplicationFiled: December 3, 2008Publication date: June 3, 2010Applicant: JACAM CHEMICALS, LLCInventors: Beth Ann Wolf, Gene H.
