ABSTRACT:
An apparatus and method of separating hydrocarbons from water and other well fluids produced from a reservoir. A controlled permeability filter selectively permits the flow of gas, oil and other hydrocarbons while restricting water flow through the filter. The permeability of certain gases or liquids through the filter can be controlled by adjusting the pressure differential across the filter. In one embodiment of the invention, the pressure differential can be selected by adjusting the filter location within a fluid column within the wellbore. In other embodiments of the invention, multiple filters can be positioned in the wellbore, and the permeability of a filter can be adjusted to control the passage of hydrocarbons therethrough.
