美国经济地质局（BEG）的研究表明，将油藏中由于经济和技术极限而舍弃的那部分原油的一半开采出来，在经济上是可能的。BEG期望将一次和二次采油的采收率提高到33％；通过发现新油田和有效地开采已发现的油田来得到更多的储量；通过油藏管理和重复勘探来增加可采储量。而不一定采用高成本的提高采收率（EOR）方法，确定采收率方面的真正突破在于定量的工程数据和地质学家定性描述的工业性结合。
Research by the U.S. Bureau of Economic Geology (BEG) shows that it is economically possible to mine half of the portion of the oil that is discarded due to economic and technological limitations in the reservoir. BEG expects to increase the recovery rate of primary and secondary oil recovery to 33%; obtain more reserves by discovering new oilfields and effectively discovering oilfields discovered; and increasing recoverable reserves through reservoir management and repeated exploration. Instead of using the high-cost EOR method, the real breakthrough in determining oil recovery lies in the combination of quantitative engineering data with the qualitative identification of geologists.
