中石化新闻讯 据燃气生产加工网址10月19日报导 因为柔和的气温降低了对燃气的要求，西得克萨斯州二叠纪冲积平原的瓦哈核心区（Waha hub）燃气期货价格自4月份至今初次出現负数。
殊不知，长期性看来，因为新冠病毒的要求毁坏造成 能源集团减少海上钻井平台，预估在例如二叠纪那样的辉绿岩冲积平原采掘原油的燃气供货将降低。而从中远期看来，瓦哈长期买卖处在很多年来的最大水准。
依据Refinitiv的标价数据信息，午刻瓦哈NG-WAH-WTX-SNL的价钱周一跌至-32便士/每上百万英热企业的平均，它是自4月份跌至-3.67美元至今的最低标准。
此外，瓦哈长期均价在今年为1.90美元/每上百万英热企业，二零二一年为2.84美金/每上百万英热企业，这将是二零一四年至今最大的一年，那时候均价为4.30美元。
而到迄今为止，今年均值为94便士/每上百万英热企业，今年为91便士，五年均值（2015-今年）为2.11美元。
今年和今年曾一度出現瓦哈负价钱，缘故是能源集团没法迅速建造管路，以紧跟与二叠纪破纪录原油生产量有关的持续提高的燃气生产量。
这驱使一些钻探商将破纪录总数的燃气放空自己，或支付让别人采掘，而不是关掉油气井，由于她们能够根据售卖石油和别的液體来填补燃气损害。
但它是在2020年稍早美石油期货行情下挫至破纪录底点以前，先前新冠病毒造成 石油要求降低速率超出制造商减少生产量的速率。
为了更好地解决石油价格狂跌，美国能源企业大幅度减少了新钻探的开支，将10月份的燃气海上钻井平台总数降至历史时间最低。
Spot natural gas prices at the Waha hub in the Permian basin in West Texas turned negative for the first time since April as mild weather cut demand for the fuel.
Longer term, however, Waha forwards were trading at their highest levels in years on expectations gas supplies from oil drilling in shale basins like the Permian will drop after low crude prices this year due to coronavirus demand destruction caused energy firms to cut rigs.
Next-day prices at Waha NG-WAH-WTX-SNL dropped to an average of minus 32 cents per million British thermal units (mmBtu) for Monday, their lowest since falling to -$3.67 in April, according to pricing data from Refinitiv.
Waha forwards, meanwhile, averaged $1.90 per mmBtu for the balance of 2020 and $2.84 for calendar 2021, which would be the highest in a year since 2014 when prices averaged $4.30.
That compares with an average of 94 cents per mmBtu so far in 2020, 91 cents in 2019, and a five-year average (2015-2019) of $2.11.
Negative Waha prices, which happened several times in 2019 and 2020, occurred because energy firms were not able to build pipelines fast enough to keep up with growing gas output associated with record Permian oil production.
That forced some drillers to flare record amounts of gas or pay others to take it rather than shut oil wells because they could make enough money selling crude and other liquids to cover their gas losses.
But that was before U.S. oilfutures tumbled to a record low in negative territory earlier this year after coronavirus caused demand for crude to drop faster than producers can cut output.
In response to the oil price plunge, U.S. energy companies have slashed spending on new drilling, cutting the oil and gas rig count to a record low in August.
