Abstract:
Gas and condensate productivities from a hydrocarbon reservoir can be enhanced using a chemical treatment composition. The chemical treatment composition includes a solvent mixture and a wettability alteration chemical. The solvent mixture includes a solvent that is operable to increase the relative permeability of gas within the hydrocarbon reservoir and the wettability alteration chemical is operable to alter the wettability of surfaces of the hydrocarbon reservoir, in each case enhancing the gas and condensate productivities from the hydrocarbon reservoir. The solvent mixture is selected to provide a chemical treatment composition with a flash point of at least 40° C. (104° F.).

Claim (Index 1):
A chemical treatment composition that enhances both gas and condensate productivities from a hydrocarbon reservoir, the hydrocarbon reservoir having a reservoir surface, the chemical treatment composition comprising:\n a wettability alteration chemical at between about 0.1% to about 10.0% by weight of the chemical treatment composition, wherein the wettability alteration chemical is selected from a group consisting of a fluorinated surfactant, a polymeric surfactant, a polymeric fluorinated surfactant, and combinations of the same, and a solvent mixture, the solvent mixture selected to provide a chemical treatment composition with a flash point of at least 40\u00b0 C., the solvent mixture including a solvent, where the solvent comprises 2-butoxyethanol, and in addition a high molecular weight alcohol combination between about 20.0% and about 40.0% by weight of the chemical treatment composition, wherein the high molecular weight alcohol combination comprises 1-pentanol and 1-hexanol, and wherein the chemical treatment composition is soluble in water with an interfacial tension of less than 0.78 dyne/cm.
