中国石化新闻网讯 据天然气加工网站10月19日报道 由于温和的天气减少了对天然气的需求，西德克萨斯州二叠纪盆地的瓦哈枢纽（Waha hub）天然气现货价格自4月份以来首次出现负值。 然而，长期来看，由于冠状病毒的需求破坏导致能源公司削减钻井平台，预计在诸如二叠纪这样的页岩盆地开采石油的天然气供应将下降。而从中长期来看，瓦哈远期交易处于多年来的最高水平。 根据Refinitiv的定价数据，翌日瓦哈NG-WAH-WTX-SNL的价格周一跌至-32美分/每百万英热单位的平均水平，这是自4月份跌至-3.67美元以来的最低水平。 与此同时，瓦哈远期平均价格在2020年为1.90美元/每百万英热单位，2021年为2.84美元/每百万英热单位，这将是2014年以来最高的一年，当时平均价格为4.30美元。 而到目前为止，2020年平均为94美分/每百万英热单位，2019年为91美分，五年平均值（2015-2019年）为2.11美元。 2019年和2020年曾多次出现瓦哈负价格，原因是能源公司无法快速修建管道，以跟上与二叠纪创纪录石油产量相关的不断增长的天然气产量。 这迫使一些钻井商将创纪录数量的天然气放空，或付款让他人开采，而不是关闭油井，因为他们可以通过出售原油和其他液体来弥补天然气损失。 但这是在今年早些时候美国石油期货价格下跌至创纪录低点之前，此前冠状病毒导致原油需求下降速度超过生产商削减产量的速度。 为了应对油价暴跌，美国能源公司大幅削减了新钻井的支出，将8月份的油气钻井平台数量降至历史新低。 王磊 摘译自 天然气加工 原文如下： Texas Waha natgas prices drop to negative on weak demand 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. |
