ABSTRACT:
A method and system for increasing oil production from an oil well producing a mixture of oil and gas through a wellbore penetrating an oil-bearing formation containing an oil-bearing zone and a selected injection zone, by driving a turbine in the oil well with the mixture of oil and gas; separating at least a portion of the gas from the mixture of oil and gas in the oil well to produce a separated gas and an oil-enriched mixture; driving a compressor with the turbine to compress at least a portion of the separated gas in the oil well to a pressure greater than a pressure in the selected injection zone to produce a compressed gas; injecting the compressed gas into the selected injection zone; and recovering at least a major portion of the oil-enriched mixture.
