Abstract:
Treatment fluids of the present disclosure may comprise an aqueous base fluid and a surfactant composition. The surfactant composition may comprise a sulfonate surfactant in an amount of from 0.01 wt. % to 2 wt. % based on the total weight of the treatment fluid composition, a plant-based oil in an amount of from 0.01 wt. % to 2 wt. % based on the total weight of the treatment fluid composition, and a zwitterionic co-surfactant in an amount of from 0.01 wt. % to 2 wt. % based on the total weight of the treatment fluid composition. The plant-based oil may comprise from 65 mol. % to 85 mol. % species comprising one or more gondoic acid moieties. Methods for recovering hydrocarbons from a subterranean formation with the treatment fluid are also disclosed.
