中国石化新闻网讯 据全球能源新闻网1月8日报道，2021年美国天然气探明储量创下新纪录，原油和凝析油探明储量有所增加，但尚未达到疫情暴发前的水平。能源需求已从疫情造成的2020年低点上升，推高了价格。
已探明储量是运营商对地质和工程数据所证明的、在现有经济和运行条件下，在未来几年内可以从已知储层开采的石油和天然气储量的估计。
探明储量的估计受到价格的严重影响。2021年原油和天然气价格上涨是探明储量估计值上涨的原因之一。
得克萨斯州的原油和凝析油探明储量比其他任何州都多，2021年探明储量净增长最大。2021年，得克萨斯州的原油和凝析油探明储量从167亿桶增加到186亿桶，增长了12%(即19亿桶)。新墨西哥州的原油和凝析油探明储量净增长排名第二(39%，14亿桶)，阿拉斯加排名第三(31%，7亿桶)。
2021年，阿拉斯加的天然气探明储量增幅最大（173%，63.3万亿立方英尺），几乎是2020年的三倍。2021年，得克萨斯州天然气探明储量增长第二大（30%，34万亿立方英尺）。新墨西哥州的天然气探明储量增幅位居第三（38%，10万亿立方英尺）。

EIA – IN 2021 US PROVED RESERVES OF NATURAL GAS SET A NEW RECORD
In 2021, proved reserves of natural gas set a new record in the United States, and proved reserves of crude oil and lease condensate increased, but not quite to pre-pandemic levels. Energy demand had risen from the 2020 lows that resulted from the COVID-19 pandemic, pushing up prices and making more U.S. resources economically viable.
Proved reserves are operator estimates of the volumes of oil and natural gas that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions.
Estimates of proved reserves are heavily influenced by prices. Higher 2021 prices for crude oil and natural gas were a contributor to higher proved reserve estimates.
Texas, where more proved reserves of crude oil and lease condensate are located than any other, saw the largest net increase in proved reserves in 2021. In 2021, Texas’s annual crude oil and lease condensate proved reserves increased by 12% (1.9 billion barrels) from 16.7 billion barrels to 18.6 billion barrels. New Mexico saw the second-largest net increase of proved reserves of crude oil and lease condensate (39%, 1.4 billion barrels), and Alaska the third-largest (31%, 0.7 billion barrels).
Alaska had the largest increase in proved reserves of natural gas in 2021 (173%, 63.3 trillion cubic feet), which almost tripled the state total compared with 2020. Texas had the second-largest increase of natural gas proved reserves in 2021 (30%, 34 trillion cubic feet). New Mexico had the third-largest increase of natural gas proved reserves (38%, 10 trillion cubic feet).
