摘要： This invention provides a method for improving oil recovery, preferably a high-viscosity oil relying on gravity drainage, by applying vibrational energy. A fracture is created at a wellbore and a fluid displacement device is inserted at or near the fracture opening. The optimum oil mobilization frequency and amplitude is determined. The fluid inside the fracture is oscillated to a prescribed range of frequency and amplitude to improve oil production. Applications for using the fracture as a delivery device for vibrational energy to enhance performance of the steam-assisted gravity drainage process, vapor-extraction gravity drainage, or cyclic steam process are provided. An application to improve recovery of heavy oil by aquifer drive or peripheral waterflood is also provided.

摘要： Methods and systems for enhanced oil recovery from a subterranean formation are provided. An exemplary includes separating fluid produced from the subterranean formation into a first fluid stream that includes an aqueous stream containing multivalent ions. At least a portion of the multivalent ions in the first fluid are removed to form a second fluid stream and the second fluid stream is injected into the subterranean formation. The first fluid stream and the second fluid stream have substantially the same interfacial tension with a hydrocarbon and substantially the same kinematic viscosity, and the second fluid stream has a total concentration of ions greater than about 100,000 ppm.

摘要： Methods for enhanced oil recovery from a subterranean formation including adding a first salt to a first aqueous stream to form a first injection stream with an increased concentration of a first ion. A second salt is added to a second aqueous stream to form a second injection stream with an increased concentration of a second ion. The second injection stream is of different composition than the first injection stream and the first injection stream and the second injection stream have substantially the same interfacial tension with a hydrocarbon and substantially the same kinematic viscosity. The first injection stream is injected into the formation at a first time and the second injection stream is injected into the formation at a second time. The first injection stream and second injection stream contact at least some overlapping portion of the formation. Oil is recovered from the overlapping portion of the formation.
