Shale oil resources have proven to be quickly producible in large quantities at relatively low cost, and have recently revolutionized the oil and gas industry. Typically, only 3 to 7% of the oil-in-place is recoverable by using current technologies. The oil content in a shale oil formation includes free oil contained in inorganic pores and trapped oil in the organic material called kerogen. The latter can represent a significant portion of the total oil and our knowledge on how to recover it is very little, yet production of shale oil currently targets only the free oil rather than the trapped oil in kerogen. Shale oil reservoirs also have a substantial capacity to store CO

页岩油资源已被证明能够以相对较低的成本迅速大量生产，最近给石油和天然气行业带来了革命性的变化。通常情况下，使用目前的技术，只有3%到7%的原地石油是可开采的。页岩油层中的含油量包括无机孔隙中的游离油和被称为干酪根的有机物质中的圈闭油。后者可能占总石油的很大一部分，我们对如何回收它的了解非常少，但页岩油目前的目标只是游离油，而不是干酪根中捕获的油。页岩油藏也有相当大的储存CO的能力
