據EIA 8月3日消息稱，根據EIA分析，由于平均油價在2020年至2022年上半年之間翻了一番多，鷹灘地層的估計經濟可采石油資源增加了15倍多，從5億桶增加到84億桶。石油和天然氣價格可能高度波動，并對經濟可采資源的估計產生重大影響，與探明儲量相比，經濟可采能源在可采石油和天然天然氣資源中所占比例較小。基于2020年WTI平均價格約為每桶40美元，亨利樞紐天然氣價格約為2美元/百萬英熱單位（MMBtu），EIA根據Enverus和Rystad Energy的數據估計，鷹灘地層的經濟可采資源量僅為5億桶石油。相反，根據WTI價格約100美元/桶（約為2022年上半年WTI平均價格）和亨利中心價格6美元/百萬英熱單位（約為2012年上半年亨利中心平均價格），EIA對經濟可采資源的估計增加至84億桶石油。

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.
