  • Patent number: 9499737
    Abstract: A method of modifying a surface of a hydrocarbon-bearing formation is disclosed. The method includes contacting the surface of the hydrocarbon-bearing formation with a fluorinated amine, and the surface of the hydrocarbon-bearing formation includes a carbonate. The method can typically include introducing a treatment composition comprising solvent and at least one of the fluorinated amine or a salt thereof into the carbonate hydrocarbon-bearing formation. Hydrocarbon-bearing formations treated according to the method are also disclosed. Certain fluorinated amines useful for treating carbonate hydrocarbon-bearing formations and methods of making them are also disclosed.

  • Patent number: 7765698
    Abstract: A method of making an electret article, from a polymeric article that has a zeta potential of greater than or less than ?7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has a pH and conductivity as follows: (i) if the article has a zeta potential of ?7.5 mV or less, then the contacting liquid has pH greater than 7 and a conductivity of 5 to 9,000 microSiemens per centimeter; and (ii) if the article has a zeta potential of greater than ?7.5 mV, then the contacting liquid has a pH of 7 or less and a conductivity of 5 to 5,500 microSiemens per centimeter. An electret article made in this manner can provide improved electret performance, particularly in electret filtration articles.
