ABSTRACT:
A method for selectively producing oil from a reservoir containing both oil and gas. A lateral or horizontal wellbore is drilled within the reservoir below the gas-oil interface, and the wellbore has an inverted producing interval that is upwardly inclining toward the tail of the well. The inverted wellbore is drilled and completed in order to improve reservoir drainage by causing gas breakthrough to occur first at the far end of the upwardly inclining producing interval. A fluid restrictor is activated to restrict gas production from this breakthrough area and to permit oil production above the restrictor.
