Abstract

See full text

The present invention discloses liquid quaternary ammonium salts that can be used to treat and coat the surfaces of the proppant sand or inorganic particles that are used in down-hole oil well fracturing operations as well as the containment structure and that these treated surfaces will cause water and oils to flow faster through the porous structure. These liquid quaternary ammonium salts can be chosen from a list that includes but is not limited to cocobis(2-hydroxyethyl)ethylammonium ethyl sulfate, benzylcocobis(hydroxyethyl)ammonium 2-ethylhexylsulfate, dibenzylcocobishydroxyethyl ammonium phenolsulfonate, didecyldimethyl-ammonium dodecylbenzenesulfonate and tallow-bis(2-hydroxyethyl)ethylammonium ethyl sulfate.
