Patent ID: 7278489

Claim:
A gas turbine driven oil lifting device for increasing production of oil over a specified time period comprising: a production column-casing consisting of a tubing connected to a gas turbine having two opposing ends defined by upper and lower portions, all positioned within the casing; the gas turbine has a turbine inlet and a turbine outlet positioned near its upper end and said gas turbine also has a turbine inlet and a turbine outlet near its lower end, all positioned within said casing; within said upper end outlet and lower end inlet is a rotor assembly for rotation of a fluid in a directionally-oriented flow; the casing is separated into two parts by a bypass packer, which is coupled to an end of the gas turbine, so as to position the entire gas turbine and tubing within the part above the bypass packer; within said tubing and positioned above said gas turbine is a check valve; fixed to said tubing is a plurality of spaced-apart spindle valves all positioned on the tubing and positioned above the check valve, with a bottom-most spindle valve having the lowest opening pressure and positioned nearest the check valve, and an upper-most spindle valve having the greatest opening pressure; and a supply tube to the gas turbine is fixedly-positioned along the tubing connected to the gas turbine near the upper end gas turbine inlet with a second check valve installed at the gas turbine outlet near the lower end.
