据EIA 8月3日消息称，根据EIA分析，由于平均油价在2020年至2022年上半年之间翻了一番多，鹰滩地层的估计经济可采石油资源增加了15倍多，从5亿桶增加到84亿桶。石油和天然气价格可能高度波动，并对经济可采资源的估计产生重大影响，与探明储量相比，经济可采能源在可采石油和天然天然气资源中所占比例较小。基于2020年WTI平均价格约为每桶40美元，亨利枢纽天然气价格约为2美元/百万英热单位（MMBtu），EIA根据Enverus和Rystad Energy的数据估计，鹰滩地层的经济可采资源量仅为5亿桶石油。相反，根据WTI价格约100美元/桶（约为2022年上半年WTI平均价格）和亨利中心价格6美元/百万英热单位（约为2012年上半年亨利中心平均价格），EIA对经济可采资源的估计增加至84亿桶石油。

Higher prices in 2022 result in increased estimates of economically recoverable oil resources in the Eagle Ford formation
In response to average oil prices more than doubling between 2020 and the first half of 2022, the estimated economically recoverable oil resources in the Eagle Ford formation increased by more than 15-fold, from 0.5 billion barrels to 8.4 billion barrels, according to EIA analysis. Oil and natural gas prices can be highly volatile and have a significant effect on estimates of economically recoverable resources, which represent a less certain portion of recoverable oil and natural gas resources than proved reserves. based on the 2020 average West Texas Intermediate (WTI) crude oil price of about $40 per barrel (b) and the Henry Hub natural gas price of about $2 per million British thermal units (MMBtu), we estimate the Eagle Ford formation’s economically recoverable resources are as little as 0.5 billion barrels of oil, based on data from Enverus and Rystad Energy . In contrast, based on a WTI price of about $100/b (approximately the first-half 2022 average WTI price) and a Henry Hub price of $6/MMBtu (approximately the first-half 2022 average Henry Hub price), our estimate of economically recoverable resources increases to 8.4 billion barrels of oil.
