ABSTRACT:
A method and system for increasing the production of hydrocarbons from a production well producing a mixture of hydrocarbons and water through a wellbore penetrating a formation having a production zone producing a mixture of hydrocarbons and water, and a selected injection zone, by separating, in the wellbore, at least a portion of the water from the mixture of hydrocarbons and water, to produce separated water and a hydrocarbon enriched mixture; injecting, by the use of a pump drivingly connected to a turbine, at least a major portion of the separated water into the selected injection zone; and recovering at least a major portion of the hydrocarbon enriched mixture.
