| titleOfInvention | Recovery of heavy oils by fracturing and injection of gas |
| abstract | High-viscosity oil is recovered from subterranean reservoirs by a cyclic process that alternately enhances the mobility of the heavy oil at increasing distances from the production well and recovers the more mobile oil that drains into the vicinity of the production well. The increased mobility of the oil is achieved by the cyclic injection of a gas having a relatively high oil solubility into the reservoir through, and alternately producing the swollen oil from, the production well. The area of the formation contacted by the injection gas is greatly increased by fracturing the oil-bearing formation prior to gas injection. The fracture permits the injected gas to be carried into those areas of the formation not otherwise in immediate communication with the well and enhances the withdrawal of oil by providing a convenient path for the swollen oil to flow through in the formation to the production well. |
