METHOD FOR TREATING HYDROCARBON-BEARING FORMATIONS WITH FLUORINATED POLYURETHANES

摘要

A method of treating a hydrocarbon-bearing formation including receiving data comprising a temperature and a brine composition of the hydrocarbon-bearing formation; selecting a treatment composition for the hydrocarbon-bearing formation comprising a fluorinated polyurethane and solvent, wherein, at the temperature, a mixture of an amount of the brine composition and the treatment composition is transparent and free of precipitated solid, and wherein the mixture does not separate into layers; and contacting the hydrocarbon-bearing formation with the treatment composition. Another method of treating a hydrocarbon-bearing formation includes contacting a limestone formation with a treatment composition comprising a fluorinated polyurethane and solvent. Hydrocarbon-bearing formations treated according to the method are also disclosed. A composition comprising a fluorinated polyurethane and a combination of solvents is also disclosed.
