2021年下半年海恩斯维尔天然气产量创新高

据钻机地带4月16日报道，得克萨斯州东北部和路易斯安那州西北部海恩斯维尔页岩区的干天然气产量在2021年下半年达到新高，2022年初产量保持相对强劲。

根据EIA的数据显示，2022年2月，海恩斯维尔的天然气产量约占美国所有干天然气产量的13%。

海恩斯维尔是美国第三大页岩气生产区。阿巴拉契亚盆地（主要位于宾夕法尼亚州、西弗吉尼亚州和俄亥俄州）的Marcellus区块是美国产量最高的页岩气油气田。

2021年，Marcellus区块的天然气日均产量为317亿立方英尺。在得克萨斯州和新墨西哥州的二叠纪区块，2021年的日均产量为124亿立方英尺，是全球第二高产区块。Marcellus、二叠纪和海恩斯维尔地区合计占美国干天然气产量的52%。

EIA表示，海恩斯维尔的天然气产量从2012年中期到2016年稳步下降，因为与其他产区相比，其生产天然气的成本相对较高。

深度在10500～13500英尺的海恩斯维尔的油井比其他区块的油井更深，钻井成本往往更高。多年来，天然气价格相对较低，这意味着钻更深的井不太经济。然而，由于天然气价格自2020年中期以来一直在上涨，生产商有动力增加正在运行的钻机数量，并使用这些钻机钻更深的井。

相比之下，阿巴拉契亚盆地马塞勒斯的井更浅——在 4000～8500 英尺之间。

随着天然气价格的波动，生产商倾向于增加或减少正在运营的钻机数量。根据贝克休斯的数据显示，自2020年下半年以来，海恩斯维尔的天然气导向钻机数量一直在稳步上升，2021年平均达到46台。

EIA补充道，自2022年初以来，生产商在海恩斯维尔地区增加了17台钻机。截至4月8日的一周内，海恩斯维尔共有64台天然气导向钻机投入运营，占美国目前运营的天然气导向钻机的45%。

近年来，海恩斯维尔的管道运输能力也有所提高。增加的运输能力使生产商能够到达美国墨西哥湾沿岸的工业需求中心和液化天然气终端。

Enterprise Products Partners 的Gillis横向管道和相关的 Acadian Haynesville Extension扩建项目于2021年12月投入使用。

在这些项目之前，Enbridge Midcoast Energy的CJ Express管道于2021年4月投入使用。这些项目为海恩斯维尔地区增加了13亿立方英尺/天的外卖输送能力，目前约为159亿立方英尺/天。

Haynesville Natural Gas Production Hits Record High In Late 2021

Dry natural gas production from the Haynesville shale play in northeastern Texas and northwestern Louisiana reached new highs in the second half of 2021, and production remained relatively strong in early 2022.

According to data by the EIA, Haynesville natural gas production accounted for about 13 percent of all U.S. dry natural gas production in February 2022.

Haynesville is the third-largest shale gas-producing play in the United States. The Marcellus play in the Appalachian Basin – mainly in Pennsylvania, West Virginia, and Ohio – is the highest-producing shale gas play in the United States.

In 2021, an average of 31.7 billion cubic feet per day (Bcf/d) of natural gas was produced from the Marcellus play. In the Permian play in Texas and New Mexico, production averaged 12.4 Bcf/d in 2021, making it the second-highest producing play. Altogether, the Marcellus, the Permian, and the Haynesville account for 52 percent of U.S. dry natural gas production.

EIA said that natural gas production in Haynesville declined steadily from mid-2012 until 2016 due to its relatively higher cost to produce natural gas compared with other producing areas.

At depths of 10,500 feet to 13,500 feet, wells in the Haynesville are deeper than in other plays, and drilling costs tend to be higher. Years of relatively low natural gas prices meant it was less economical to drill deeper wells. However, because natural gas prices have increased since mid-2020, producers have an incentive to increase the number of rigs in operation and use those rigs to drill deeper wells.

By comparison, wells in the Marcellus in the Appalachian Basin are shallower – between 4,000 feet and 8,500 feet.

Producers tend to increase or decrease the number of drilling rigs in operation as natural gas prices fluctuate. The number of natural gas-directed rigs in Haynesville has been rising steadily since the second half of 2020 and reached an average of 46 rigs in 2021, according to data by Baker Hughes.

EIA added that producers have added 17 rigs in the Haynesville region since the beginning of 2022. For the week ending April 8, 64 natural gas-directed rigs were operating in Haynesville, representing 45 percent of natural gas-directed rigs currently operating in the United States.

Pipeline takeaway capacity out of Haynesville has also increased in recent years. The additional capacity allows producers to reach industrial demand centers and liquefied natural gas terminals on the U.S. Gulf Coast.

The Enterprise Products Partners’ Gillis Lateral pipeline and the associated expansion of the Acadian Haynesville Extension entered into service in December 2021.

Before that project, Enbridge Midcoast Energy’s CJ Express pipeline entered service in April 2021. These projects added 1.3 Bcf/d of takeaway capacity in the Haynesville area, which is currently estimated to total 15.9 Bcf/d.
