20100233492 | COMPOSITIONS FOR AQUEOUS DELIVERY OF FLUORINATED OLIGOMERIC SILANES - The invention relates to a dilutable, non-aqueous concentrate and an aqueous dilution used for aqueous delivery of fluorinated oligomeric silanes to a substrate, a method of treating a substrate with the aqueous dilution composition to render it oil and water repellent, and articles having coatings made from the aqueous dilution. | 09-16-2010 |
20100270020 | METHODS FOR TREATING HYDROCARBON-BEARING FORMATIONS WITH FLUORINATED ANIONIC SURFACTANT COMPOSITIONS - Methods of treating a hydrocarbon-bearing formation having brine and liquid hydrocarbons and treated hydrocarbon-bearing formations. The methods include contacting the hydrocarbon-bearing formation with a composition comprising solvent and a fluorinated anionic surfactant. In some embodiments, the solvent solubilizes the brine in the hydrocarbon-bearing formation without causing the fluorinated anionic surfactant to precipitate. In some embodiments, the solvent includes at least one of a polyol or polyol ether independently having from 2 to 25 carbon atoms and at least one of water, a monohydroxy alcohol, an ether, or a ketone, wherein the monohydroxy alcohol, the ether, and the ketone each independently have up to 4 carbon atoms. | 10-28-2010 |
20100270021 | METHODS FOR TREATING HYDROCARBON-BEARING FORMATIONS WITH FLUORINATED POLYMER COMPOSITIONS - A method of treating a hydrocarbon-bearing formation and treated hydrocarbon-bearing formations. The method includes contacting the hydrocarbon-bearing formation with a composition having solvent and a fluorinated polymer. The fluorinated polymer has units having formula (I): A method for making a composition containing these units is also disclosed. | 10-28-2010 |
20110056689 | METHODS FOR TREATING HYDROCARBON-BEARING FORMATIONS HAVING BRINE - Method of treating a hydrocarbon-bearing formation having brine and treated hydrocarbon-bearing formations. The method includes contacting a hydrocarbon-bearing formation with a composition comprising solvent and a polymer. The polymer comprises divalent units represented by formula: (formula I); and a plurality of alkyleneoxy groups. In some embodiments, the solvent at least one of solubilizes or displaces the brine in the formation. In some embodiments, the solvent includes at least one of a polyol or polyol ether independently having from 2 to 25 carbon atoms and at least one of water, a monohydroxy alcohol, an ether, or a ketone, wherein the monohydroxy alcohol, the ether, and the ketone each independently have up to 4 carbon atoms. Hydrocarbon-bearing formations and proppants treated with the polymer are also disclosed. | 03-10-2011 |
