Enhanced oil recovery currently uses a quite remarkable amount of energy: 1.7 quadrillion btu of gas around the world every year, according to GlassPoint.

目前，提高石油开采使用相当大的能量：根据玻璃点太阳能公司所述，每年，世界各地需要使用1.7×1015每百万英（制）热单位（BTU）的天然气。

Which is why a lot of the carbon captured today is still used in a process  called enhanced oil recovery.

这就是为什么今天捕获的大量碳仍然用于称为强化采油的过程。
