Patent number: 7658229Abstract: The present invention is directed to producing fluid from an oil or gas well by means of a combination intermittently filled down hole chamber accumulation device and a connected upper continuous gas lift flow system, separated by an inline one-way reverse flow check valve. A two-way purge and vent valve controls the distribution of high pressure gas. The two-way valve first injects high pressure gas into the chamber accumulation device to displace the fluid from the chamber into the continuous flow conduit. The two-way valve then vents the residual high pressure gas from the chamber into a separate low pressure conduit to the surface. The valve also provides high pressure gas to the continuous flow conduit to assist in the production of the fluid.Type: GrantFiled: March 31, 2006Date of Patent: February 9, 2010Assignee: BST Lift Systems, LLCInventors: Billy G. Becker, David A. Tucker

Patent number: 5427133Abstract: A gas lift assembly and gas lift valve positioned in coiled tubing in which the coiled tubing housing and gas lift valve are flexible for allowing the coiled tubing to be spooled. The gas lift valve is wireline retrievable for allowing gas lift valves to be removed for allowing other tools to pass through the coiled tubing. The gas lift valves are selective in that they will seat a selected coiled tubing housing as each valve will match a mating coiled tubing housing.Type: GrantFiled: August 26, 1993Date of Patent: June 27, 1995Assignee: Camco International Inc.Inventor: Ronald E. Pringle

Patent number: 5217067Abstract: An injection valve for use in a well, for example, an oil well, enables gas to be injected to cause the oil or other fluid to be lifted to the surface. The valve has a valve body having an inlet at one end and an outlet at the other end, which are adapted to be fitted into conventional production oil tubing. Within the valve body, there are a plurality of ducts extending through between the inlet and the outlet, for the flow of oil or other fluid. A gas injection port opens into the outlet of the valve body and there is at least one gas inlet opening in the side of the valve body, which is connected to that gas injection port. This enables compressed gas to be sent down the well between the casing and the tubing, and injected through the gas injection port into the flow of oil.Type: GrantFiled: July 30, 1991Date of Patent: June 8, 1993Inventors: Robert Landry, Kenneth W. Reber

Patent number: 4111608Abstract: A casing pressured operated, variable orifice valve is employed as the operating valve in a single point injection well assembly with tubing pressure (fluid) operated unloading valves acting above the operating valve to provide a continuous flow system. The operating valve includes a throttling range which extends between optimum injection gas pressure levels based on the amount of injection gas pressure available at the well head to thereby increase the overall efficiency of the system. The variable orifice valve includes a pressure charged bellows and a coil spring in series to produce a linear resultant load rate which in turn cooperates with contoured closure surfaces in the valve to produce a linear relationship between orifice size and injection gas pressure. Gas is thus injected into the production column or tubing at a rate which is linearly related primarily to the casing pressure with the throttling range of the operating valve producing a broad response in the gas injection rate.Type: GrantFiled: February 23, 1976Date of Patent: September 5, 1978Assignee: Schlumberger Technology CorporationInventors: J.
