An apparatus and method for a subsea wellhead station having one or more producing well holes wherein an oil production control unit is separate from and adjacent to a wellhead unit for a well hole, each of said units being removable for repair and maintenance at a remote location independently of the other unit. The production control unit contains necessary equipment affording remote control of production of oil, directing such production into test or collection lines, monitoring pressures of production oil from its associated well hole, controlling gas injection into the well hole, and maintaining and controlling desired production oil pressure conditions.
