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.).
