Abstract:
The present disclosure describes compositions and a method for forming such compositions. More specifically, inorganic microparticles and surface modified silica nanoparticles are mixed to form a composition. The surface modified silica nanoparticles are present in the composition in an amount sufficient to decrease the coefficient of friction relative to a comparable composition that is free of surface modified silica nanoparticles.

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.
