翻译某篇文章遇到一个不认识的词：flowbacks
Overall, for the segment of the gas lifecycle they investigated, the UTteam found methane emissions that were lower than EPA’s latest estimates. Emissionsfrom “completion flowbacks” were 98% lower,partially offset by somewhat higher observed leaks from valves and otherequipment. 该词在这句话中,希望懂的朋友帮忙翻译下,我是在翻译页岩气相关文章时翻到的~

答案
flowbacks 是倒流,回流的意思.这里应该是指开采技术（比如水力裂压法）下,将水和其他物质利用高压达到地下,然后通过压力是页岩气能收集到井里.这当水回流的时候,当中融化掉一些Methane,产生的一些排放效果.这里看来说是这个方法,在水回流导致排放的情况改善达98%.
