Method of increasing injectivity of fluids into formations
Patent
·
OSTI ID:5000437
Recovery of fluids from subterranean formations is accomplished by injecting into the formation, first a slug of miscible-type material, second, displacing the first slug with a drive fluid, then fracturing the formation. The fracture is controlled so that it does not extend substantially into the slug of soluble oil. A second amount of the drive fluid is then injected to displace hydrocarbons. (10 claims)
