Abstract: The present disclosure provides for a sandstone-containing oil reservoir additive composition that includes (a) a nonionic wettability alteration agent having Formula (I): and (b) an injection fluid. For Formula (I), R is an alkyl residue from a branched secondary alcohol initiator, where R can have a carbon number of C4 to C10, x is from 3 to 10 and y is from 1 to 20. The injection fluid can be selected from the group consisting of sea water, engineered water, injection brine, produced brine or combinations thereof. The nonionic wettability agent in the sandstone reservoir additive composition can be from 0.01 weight percent (wt %) to 20 wt % based on the total weight of the sandstone reservoir additive composition. The sandstone-containing oil reservoir additive composition can be used in enhance oil recovery operations, such as a waterflooding operation or a carbon dioxide flooding operation.

Abstract: The present invention includes a foam-forming composition for use in enhanced oil recovery, and a method of using said foam-forming composition for recovering oil. The foam-forming composition of the present invention comprises a nonionic surfactant, in particular an alcohol-alkoxylate, and an anionic surfactant, in particular an alkyl diphenyloxide (di)sulfonate, where the foam-forming composition promotes a formation of a stable foam formed of a CO2 and water.

Abstract: A surfactant composition including a C10 AOS and/or C12 AOS, and an effective amount of at least one solubilizing component so as to increase brine tolerance of the composition is disclosed. The solubilizing component comprises a mixture of
where X is H, an alkali metal, alkaline earth metal or ammonium, and R is a linear C6-C16 alkyl group. A method of recovering hydrocarbons from a reservoir during gas injection into said reservoir is also disclosed which involves at least periodically injecting the gas and a foam-forming surfactant composition into the reservoir so as to assist in the recovery of hydrocarbons from the reservoir.-

Abstract: Surfactants constructed from three synthetic building blocks that contain multiple hydrocarbon chains, ethyleneamine, and alkyl sulfonate salt groups, were shown to possess good thermal stability, and foamability, and high foam profiles. The materials are targeted for high temperature foaming applications, such as foam flooding enhanced oil recovery to improve conformance control and other oil and gas downhole foaming applications.
