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