淹没在采出水中:勘探与生产公司寻求经济的方式来应对水激增

紧张的处置限制将有益的再利用推到了生产水管理的首要位置。

由于水产量往往超过石油和天然气产量,勘探与生产公司开始采用回收、处置和有益再利用来处理水,但每种解决方案都有其局限性。

XRI 水务副总裁 John Durand 告诉 E&P,一些地区(例如特拉华盆地)的水油比 (WOR) 高达每 1 桶原油 10 桶水,尽管行业平均 WOR 接近每 1 桶原油 4 桶水。这意味着,如果二叠纪盆地每天抽出 500 万桶原油,则伴随约 2000 万桶水。

Drowning in Produced Water: E&Ps Seek Economic Ways to Handle Water Surge

Strained disposal limits push beneficial reuse to the forefront for produced water management.

With water production often outpacing oil and gas, E&P companies turn to recycling, disposal and beneficial reuse to handle the water, but each solution has its limitations.

Some regions, such as the Delaware Basin, have a water-oil ratio (WOR) as high as 10 bbl of water per 1 bbl of crude, although an industry average WOR is closer to 4 bbl of water per 1 bbl of crude, XRI Water Vice Chairman John Durand told E&P. That means if the Permian Basin is pumping out 5 MMbbl/d of crude, it is accompanied by about 20 MMbbl/d of water.
