To prevent barium sulfate scale from forming in the North Sea Brae field producing wells, Marathon Oil Co. UK Ltd. is successfully employing thin-film composite (nanofiltration) membranes for removing sulfate from injected seawater. In the early 1980s, FilmTec Corp., a Dow Chemical Co. subsidiary, first developed these composite membranes, which now are in their third generation. Marathon Oil Co. holds the patent for the specific nanofiltration membrane process for mitigating scale formation and deleterious reservoir effects. This first article in a three-part series describes membrane technology. The remaining articles detail specific membrane performance characteristics and field experiences in the Brae fields.
