The oil and gas producing regions of Oklahoma have 45 billion barrels of oil which will be left in the ground, or "stranded oil", following the use of today's oil recovery practices. A major portion of this "stranded oil" is in old reservoirs that appear to be technically and economically amenable to enhanced oil recovery (EOR) using carbon dioxide (CO2) injection. This report evaluates the future oil recovery potential in the large oil fields of Oklahoma and the barriers that stand in the way of realizing this potential. The report then discusses how a concerted set of "basin-oriented strategies" could help the Oklahoma's oil production industry overcome these barriers and capture the large "stranded oil" prize.
