Maximising Enhanced Oil Recovery Opportunities in UKCS Through Collaboration

Abstract: The UK Continental Shelf (UKCS) is one of the most mature offshore basins in the world. Achieving optimal recovery from the basin is demanding, but as the anticipated ultimate recovery factor is 46% (1) of oil initially in place, there is still significant opportunity to optimise recovery from the existing oil fields. PILOT, a partnership between the UK Oil and Gas industry and the UK Government, has been re-focussing its efforts on maximising North Sea recovery. There are currently only two Enh… Show more
