Abstract:
1. A method of treating a subterranean formation comprising: introducing a cement composition into a well bore, wherein the cement composition comprises cement, water, and a particulate elastomer having a specific gravity of at least about 1.6, wherein the particulate elastomer comprises at least one thermoplastic selected from the group consisting of: a fluorinated polymer of ethylene and propylene; a polymer of tetrafluorethylene and perfluorovinylether; a polymer of tetrafluoroethylene and ethylene; a polymer of tetrafluoroethylene and hexafluoropropylene; a polymer of vinylidene fluoride; a polymer of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride; perfluoroalkoxy polymer resin; chlorotrifluoroethylene; fluorinated ethylene-propylene; polyethylenetetrafluoroethylene; polyvinylfluoride; polyethylenechlorotrifluoroethylene; polyvinylidene fluoride; polychlorotrifluoroethylene; a perfluoroelastomer; a fluoro-carbon elastomer; polyamide imide, polyetherether ketone, polyphenylene sulfide, polyetherketone; and a combination thereof; and allowing the cement composition to set in the well bore.
