Abstract
The present invention relates to an aqueous fluid useful for the recovery of a liquid hydrocarbon from subterranean reservoirs comprising an aqueous media and a surfactant blend. The aqueous fluid has an alkaline pH. The surfactant blend comprises at least one synthetic polyisobutylene surfactant and at least one secondary surfactant selected from the group consisting of sulfonate surfactants, alcohols and nonionic surfactants. The surfactant blend lowers the interfacial tension between hydrocarbon oil and the aqueous fluid.
