ABSTRACT:
A method and apparatus for the downhole disposal of the water component of production fluid while using gas lift techniques to lift the hydrocarbon component to the surface is disclosed. Separation of the hydrocarbon component and the water component takes place downhole by gravity in an annulus formed between the well casing and a tubing string. The water component may be disposed of or utilized to carry out a water-flood of either overlying or underlying subterranean formations. As a result, the lifting, handling and disposal of the water component of the production fluid on the surface is minimized.
