Abstract: Disclosed herein are compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations (tight shale reservoirs). The flowback compositions include an anionic dimer surfactant, an anionic monomer surfactant, and a demulsifier. The flowback compositions convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations. The flowback composition are useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.

Abstract: This invention relates generally to novel foamer compositions for treatment of oil and gas wells to enhance production. The invention provides a method of foaming a fluid. The method includes introducing into the fluid a foam-forming amount of a composition comprising at least one long chain fatty acid and at least one organic solvent. An example of the long chain fatty acid is tall oil fatty acid and an example of the organic solvent is ethyleneglycol monobutyl ether.

Abstract: Compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean reservoirs. The compositions include a dialkyl dimethyl ammonium surfactant, an amphoteric surfactant, and a solvent. The concentrated compositions are storage stable and easily diluted with a water source such as produced water to form injectates suitable for injecting into one or more hydrocarbon-bearing subterranean reservoirs. The injectates convert oil-wet rocks to water-wet but do not cause formation of emulsions with hydrocarbon compounds within the subterranean environment. Injection of the injectates into a reservoir results in an increase in the yield of hydrocarbons recovered, in particular from low permeability, low porosity reservoirs such as those formed by or encountered in hydraulic fracturing and/or in certain geographic locations.
