据油价网2021年4月16日休斯敦报道，美国能源信息署(EIA)4月16日表示，由于2月份的冬季风暴，今年采暖季节的天然气净提取量比5年平均水平高出了10.6%。
在2020/2021年冬季采暖季节的头几个月，气温比正常情况要温和，但2月份的寒流导致天然气采暖需求创纪录，同时由于井口冻结，减少了美国的天然气产量。
EIA表示，结果是，截至2021年3月31日，美国本土48个州(传统采暖季节结束时)库存的天然气总量为17780亿立方英尺，比采暖季节结束时的五年平均水平低了1.4%。
在冬季暴风雪期间，德克萨斯州的天然气产量下降了45%，主要原因是冰冻天气。2月17日，德克萨斯州和美国中部大部分地区的干天然气产量下降了21%，最低为697亿立方英尺/天。
与此同时，就在德州冻结之前，美国通过管道出口了创纪录数量的液化天然气(LNG)和天然气，这也导致了在产量低迷和供暖需求创纪录的情况下，更多的天然气被从储库中提取。
2月份的极端冬季天气导致了美国有史以来第二大天然气需求量的飙升。
EIA表示，美国本土48个州2月份天然气的月净使用量总计为7780亿立方英尺，这是自2011年以来2月份天然气的最大使用量。今年2月，天然气储库的净使用量占供暖季节天然气储库总使用量的37%，而此前5个供暖季节的这一比例为24%。根据EIA的数据，在2月19日结束的一周内，包括德克萨斯州在内的美国中南部地区的天然气提取量达到了创纪录的1560亿立方英尺。

Texas Freeze Led To 10.6% Higher Natural Gas Withdrawals
Due to the winter storms in February, net natural gas withdrawals from storage this heating season exceeded the five-year average by 10.6 percent, the Energy Information Administration (EIA) said on Friday.
The first few months of the 2020/2021 winter heating seasons saw milder temperatures than normal, but the cold snap in February resulted in record demand for heating, while wellheads froze and reduced natural gas production in the United States.
As a result, working natural gas in storage in the Lower 48 states as of March 31, 2021—the traditional end of the heating season—totaled 1,778 billion cubic feet (Bcf), which was 1.4 percent less than the five-year average for the end of the heating season, EIA said.
During the winter storms, natural gas production in Texas collapsed by 45 percent, primarily due to freeze-offs. Total U.S. dry natural gas production during the Freeze in Texas and much of the central part of the United States declined by 21 percent, to as low as 69.7 Bcf/d on February 17.
At the same time, just before the Texas Freeze, America was exporting record volumes of liquefied natural gas (LNG) and gas via pipelines, which also contributed to more withdrawals from storage amid low production and record demand for heating.
The extreme winter weather in February resulted in the second-largest natural gas withdrawal ever as demand spiked.
Monthly net withdrawals of natural gas in the Lower 48 states in February totaled 778 Bcf, which the largest amount of natural gas withdrawn during February since 2011, the EIA said. Net withdrawals in February accounted for 37 percent of all withdrawals from natural gas storage during the heating season, compared with 24 percent during the previous five heating seasons. A record amount of natural gas, 156 Bcf, was withdrawn during the week of February 19 in the South Central region, which includes Texas, according to EIA data.
