摘要:
Methods and cement compositions are provided for sealing a subterranean zone penetrated by a wellbore, wherein the cement composition comprises zeolite, cementitious material, and a mixing fluid.
摘要:
A method and cementing composition is provided for sealing a subterranean zone penetrated by a well bore, wherein the cementing composition comprises a mixture of cementitious material, a polymeric cement cohesion additive, and sufficient water to form a slurry. The polymeric cement cohesion additive is a high molecular weight hydroxyethylcellulose. The method comprises placing the cement composition in the subterranean zone and allowing the cement composition to set into a solid mass therein.

摘要:
A ported tubular is provided for use in casing a wellbore, to permit selective access to the adjacent formation during completion operations. A system and method for completing a wellbore using the ported tubular are also provided. Ports within the wellbore casing may be opened, isolated, or otherwise accessed to deliver treatment to the formation through the ports.

摘要:
A cement composition and method of applying remedial cement to a downhole perforation is described. The method involves the sequential delivery of a phosphate acid activator and a silicate suspension to the perforation to allow in situ reaction of the activator with the binder within the perforation, thereby forming a phosphosilicate plug.
