The results are presented of a pilot test of the propane slug process on the watered-out Yates Sand of the Atlantic Richfield operated W. D. Johnson lease, S. Ward field in W. Texas. The Yates Sand in S. Ward field had undergone a very successful secondary recovery operation by waterflooding. In the case of the W. D. Johnson lease, secondary recovery was 3 times that of primary resulting in a total recovery by both primary and secondary of 63% of the original oil-in-place. At the time the propane pilot was initiated, the waterflood was in its final stages with the pilot area being nearly depleted. A propane slug pilot was undertaken as an experiment to determine if the process would be a successful tertiary mechanism in the field as had been indicated in the laboratory. A closed 5-spot with injection into the 4 corner wells and production from the center well was used for the pilot test. The pilot area covered approx. 10 acres. In undertaking this pilot, a total of 88,000 bbl of propane were injected into the 4 corner wells. Between one-fourth and one-third of the injected propane probably swept the enclosed pilot area. The propane was followed first by gas, and then alternately by gas and water.
