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: A method of enhanced oil recovery that includes injecting a composition including an hyperbranched polyglycerol into an injection well in a subterranean oil-bearing reservoir, the hyperbranched polyglycerol being a primary alcohol that is a reaction product of a C2 to C25 carbon alcohol and a plurality of glycidols; and displacing oil in the subterranean oil-bearing reservoir using the composition.
