Novel single-well field test of a micellar solution slug
A single-well field test of a micellar solution slug driven by a mobility buffer was performed on the Henry lease in the Robinson sand in Crawford County, Illinois. The average porosity of the reservoir was 20 percent, and the range of permeability was 100 to 300 md. The crude had a viscosity of 7 cp and a gravity of 36/sup 0/ API. After waterflooding, the reservoir water contained 20,000 ppM TDS. The micellar slug contained 70 percent water and 8 percent active petroleum sulfonate. Dow Pusher 700 was dissolved in water (500 ppM TDS) to form the mobility buffer. The efficiency of oil displacement was evaluated by using core-test oil saturations. All of the oil was removed from the first 13 feet from the injection well. Thereafter, most of the swept portion of the reservoir had an oil saturation of 15 to 20 percent residual oil.
