尽管废弃油井不再产油，但它们仍会造成严重的环境问题。Occlusion 和 Envana 希望通过其 Go2Green 油井退役工艺解决“数十万口油井问题”。
干涸的油井也许已经无法为勘探与生产公司创造收入，但它们无疑仍在产生问题，因为它们会向空气中释放温室气体并泄漏到水道中。
2021 年，联邦政府试图解决其中的一些问题，批准了 47 亿美元的“孤儿井计划”预算，以支持联邦、部落、州和私人土地上的封堵和废弃作业。
但问题依然存在。美国环境保护署 (EPA) 估计，美国有 370 万口废弃油气井，其中只有约 42% 得到了封堵。

Despite no longer producing, abandoned wells pose a significant environmental problem. Occlusion and Envana look to remedy the “couple hundred thousand-well problem” with their Go2Green process for well retirement.
Dried up wells may have ceased revenue generation for E&Ps, but they are definitely still generating problems by releasing greenhouse gases into the air and leaking into waterways.
In 2021 the federal government tried to tackle some of these issues with the approval of a $4.7 billion budget for the Orphaned Wells Program to support plugging and abandonment operations across federal, tribal, state and private lands.
Yet the problem still persists. The U.S. Environmental Protection Agency (EPA) estimates there are 3.7 million abandoned oil and gas wells in the U.S., with only around 42% having been plugged.
