Abstract: A hydrocarbon lift system and method for increasing petroleum production from an enclosed subterranean reservoir to the earth's surface comprises a column of buoyant balls in an outer pipe configured to entrain the buoyant balls into a first fluid in an annulus formed with an inner pipe drill string. A pressure differential in the inner pipe with respect to the reservoir via the entrained buoyant balls in a second fluid therein lifts the second fluid and the entrained balls via the inner pipe to increase petroleum production to the to earth's surface. A controlled rise velocity of the buoyant balls and the second fluid is predetermined by a ratio of a mass density of the buoyant balls to a mass density of the second fluid being greater than a mass density of the buoyant balls to a mass density of the first fluid for an increase over time in oil production.

Abstract: The disclosed hydrocarbon lift system and method prohibits water-coning in production of oil from a subterranean reservoir to the earth's surface. The system comprises a well bore with a first and a second section. The first section has perforations which draw a first fluid into and up the well bore based on a negative pump pressure applied thereto. The second section has perforations which draw a second fluid into the well bore based on a differential pressure between the pump pressure and a lower induced pressure therein. The system also comprises a venturi structure fixtured into the well bore. The venturi structure has flaring ends connected by a constricting throat defining perforations therein. The constricting throat perforations draw the second fluid through the second section perforations into the venturi throat in response to the lower induced pressure in the second section created by an increased first fluid velocity there through.

Abstract: As disclosed, a buoyant ball assisted hydrostatic lift system and method for lifting fluid(s) from an enclosed subterranean reservoir to the earth's surface, comprises a pipe string configured at a steady state gas pressure with any quiescent gas escape offset by an equal gas input. The system also includes a plurality of buoyant balls in the pipe string; the balls configured to at least one of displace a fluid mass and have a surface friction moving in fluid(s) therein. The system additionally includes a column of the buoyant balls in the pipe string, an aggregate weight of the balls configured to entrain the balls into a fluid in an annulus formed with an outer bore pipe. The system further includes a hydrostatic pressure differential in the annulus with respect to the reservoir via the buoyant balls, the pressure configured to lift fluid(s) in the annulus to the surface.
