轻质致密油的排放通常始于伴生气。一种选择可能是利用直接空气捕获（DAC）技术从空气中捕获CO 2 ，而不是燃烧滞留的甲烷。这项研究对全球天然气/石油比 (GOR) 数据进行了分类，以确定当前生产的轻质原油，这些原油可以通过 DAC 机制实现碳中和。然后，它会考虑支持或不鼓励这种方法的操作方面，包括靠近 DAC 单元的合适位置以及靠近地下利用或存储机会。
作者之前的工作将碳中性原油（CNCO）定义为在到达销售点之前已经抵消了其可燃产品排放的CO 2的原油。
Emissions for light tight oil often begin with associated gas. Rather than flare the stranded methane, an option may be to use it to power capture of CO2 from the air using direct air capture (DAC) technologies. This study catalogs global gas/oil ratio (GOR) data to identify currently produced light crude oils that could be rendered carbon-neutral through the DAC mechanism. It then considers operational aspects, including proximity to a suitable location for a DAC unit and proximity to subsurface utilization or storage opportunities, that favor or discourage this approach.
Previous work by the author defined carbon-neutral crude oil (CNCO) as crude oil that has offset the CO2 to be emitted by its combustible products before its arrival at the sale point.
