这鼓舞了煤气生产商紧追页岩层丰富的业态石油，例如北达科他州的巴肯。

从乐观的角度，用不了几年巴肯和别的页岩层就能够每天生产3百万桶油。

However , the eia specifically includes oil from north dakota 's bakken shale deposits in its calculations , which in recent years have become a significant source of unconventional crude .

然而，美国能源信息署明确包括了北达科洲的巴肯页岩中存储的石油，近年来，这些变成非常规原油的一个重要来源。

Now the bakken oilfield is pumping out more than 550000 b / d of shale oil , and williston , the town at the centre of the field , is booming .

现在，巴肯油田日产页岩油超过55万桶，而位于油田中心的威利斯顿镇则时来运转。
