Abstract
A conformance improvement method involves injecting, via an injection well, a first water slug into a subsurface reservoir. A second water slug is injected, via the injection well, into the subsurface reservoir. The first and second water slugs have different viscosities, at least one of the first and second water slugs includes a surfactant, and the first and second water slugs combine with oil in the subsurface reservoir to form a microemulsion in a layer of the subsurface reservoir. A fluid is injected, via the injection well, into the subsurface reservoir. Oil is collected, via a production well, from the subsurface reservoir. The injected fluid causes the oil to move into the production well.
