Method of increasing sludge oil yield

Abstract

The invention relates to the oil industry, in particular to methods for increasing the oil yield of a reservoir. According to the invention, in the claimed method for increasing the oil yield of a reservoir, which consists in injecting an aqueous solution of a surfactant into the reservoir through an injection well, a 0.05% solution of the EC 9660 A dispersant in the reservoir water is used as a surfactant. Diesel-alkali waste is added to the injected dispersant solution in an amount of 3% of its volume.
