Earth Boring, Well Treating, And Oil Field Chemistry > Earth Boring > Contains Organic Component > Organic Component Is Solid Synthetic Resin > Resin Is Polymer Derived From Ethylenic Monomers Only (e.g., Maleic, Itaconic, Etc.) > Polymer Derived From Acrylic Acid Monomer Or Derivative Polymer Derived From Acrylic Acid Monomer Or DerivativePolymer Derived From Acrylic Acid Monomer Or Derivative patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.01/18/07 - 20070015667 - Method and composition for injection at a tunnel boring machine A method of boring a tunnel by means of an earth pressure balance tunnel boring machine, comprising the injection at the cutting head of a foamed aqueous solution and an aqueous solution of a water-soluble acrylic acid-based polymer. The method allows easier tunnel boring in soft, sticky soils. ... 11/30/06 - 20060270563 - Compositions having hase rheology modifiers A monomer compound that contains at least one polymerizable functional group per molecule, and at least one bicycloheptyl-, bicycloheptenyl-, or branched (C5-C42)alkyl-polyether radical per molecule, wherein the bicycloheptyl- or bicycloheptenyl- polyether radical may optionally be substituted on one or more of the ring carbon atoms by one or two (C1-C6)alkyl ... 09/28/06 - 20060217270 - Wellbore servicing fluids comprising resilient material A wellbore fluid comprising a carrier fluid and a resilient material, wherein the resilient material reduces in volume upon exposure to a compressive force, and further wherein the resilient material increases in volume upon a decrease in the compressive force. ... 08/25/05 - 20050187113 - High performance water-based mud system A drilling fluid or mud additive having several components, including leonardite (humic acid); potassium acetate; partially hydrolyzed polyacrylamide (PHPA); polyanionic cellulose polymer (PAC); sulfonated asphalt; sulfoalkylated tannin; polystyrene maleic anhydride copolymer; micronized cellulose fiber; and calcium carbonate. These components are preferably premixed in a dry formulation as a powder or ... ### FreshPatents.com Support |
