Results are presented for three evaluation core tests drilled at the M-1 Project in the Robinson Field of southern Illinois. The cores were taken near three logging observation wells which have been used to follow injected fluid movement through the reservoir in one-quarter of a 2-1/2 acre 5-spot. Core oil saturation, oil displacement efficiency and vertical conformance are related to slug size, geologic characteristics and reservoir properties. The Robinson sand in the core test wells can be divided into at least three zones that show different fluid movement. These zones are also indicated by the observation well logs. Sulfonate was detected in all selected core sample extractions. Further analysis showed that the low oil saturation samples had lost more of the water-soluble sulfonate components - that is, the sand had been flushed better by the polymer solution following the micellar slug. Where the slug has been effectively displaced, a considerable reduction in reservoir oil saturation is occurring.
