Abstract: An aqueous based coating composition comprising a fatty amine quaternary having the structure of formula (I): R1R2R3R4N+X? wherein R1, R2, R3, and R4 are independently selected from saturated or unsaturated, linear or branched, substituted or unsubstituted alkyl, aralkyl, or alkenyl groups comprising from 1 to 30 carbon atoms, whereby at least one of R1, R2, R3, and R4 is a C12-C30 group, and X? is an anion from an inorganic or organic acid, is provided. The fatty amine quaternary may contain ethoxy and/or propoxy groups. One or more of R1, R2, R3, and R4 may be substituted and contain one or more hydroxyl substituents or ether linkages. Methods for imparting water resistance to a wood substrate having up to 100% moisture by applying a coating composition having the fatty amine quaternary of formula (I), and for preparing an aqueous coating composition comprising the fatty amine quaternary of formula (I) are provided.

Abstract: Methods of using a clay stabilizing agent to inhibit swelling and/or migration of clay subterranean materials upon exposure to water, wherein the clay stabilizing agent is selected from quaternary ammonium salts according to Formula I, Formula II, Formula III, Formula IV, Formula V, and combinations thereof.

Abstract: Methods of acidizing a subterranean formation penetrated by a wellbore that include the steps of (a) injecting into the wellbore at a pressure below subterranean formation fracturing pressure a treatment fluid having a first viscosity and including an aqueous acid and a gelling agent of Formula II: wherein R1 is (CxHy), wherein x ranges from 17 to 21 and y=2x+1 or 2x?1; R5 is hydrogen or —CH3; R6 is —CH2—CH2—CH2—; and R2, R3, and R4 are each —CH3; (b) forming at least one void in the subterranean formation with the treatment fluid; and (c) allowing the treatment fluid to attain a second viscosity that is greater than the first viscosity.
