EIA 报告称 2024 年美国页岩天然气产量将下降

2024 年 10 月 24 日

(WO) 美国能源信息署 (EIA) 的一份报告显示,2024 年前 9 个月,美国页岩和致密地层天然气产量(占干天然气产量的 79%)与 2023 年同期相比略有下降。如果这一趋势持续到 2024 年剩余时间,这将是自 EIA 于 2000 年开始收集这些数据以来,美国页岩气产量首次出现年度下降。

2024 年 1 月至 9 月,美国页岩气总产量与 2023 年同期相比下降约 1%,至 812 亿立方英尺/天 (Bcf/d),而美国其他干天然气产量则增长约 6%,至 221 亿立方英尺/天。2024 年 1 月至 9 月,美国干天然气总产量平均为 1033 亿立方英尺/天,与 2023 年同期基本持平。

今年迄今为止页岩气产量下降主要是由于海恩斯维尔和尤蒂卡页岩气产量下降。2024 年 1 月至 9 月,与 2023 年同期相比,海恩斯维尔页岩气产量下降了 12%(18 亿立方英尺/天),尤蒂卡页岩气产量下降了 10%(6 亿立方英尺/天)。与此同时,二叠纪页岩气产量增长了 10%(16 亿立方英尺/天)。马塞勒斯页岩气产量领先于美国页岩气产量,但产量持平。

位于德克萨斯州东北部和路易斯安那州西北部的海恩斯维尔气田是一个干天然气层。阿巴拉契亚盆地的尤蒂卡和马塞勒斯气田除了干天然气外,还生产凝析油。在这三个气田中,天然气价格主要推动钻井和开发井。美国基准亨利中心日天然气价格自 2022 年 8 月以来普遍下降,并在 2024 年上半年创下历史新低,导致钻探天然气井的利润下降,尤其是在海恩斯维尔。海恩斯维尔和阿巴拉契亚盆地的几家运营商因价格创历史新低而关闭了天然气生产,并打算在 2024 年下半年继续减产。

相比之下,德克萨斯州西部和新墨西哥州东南部二叠纪盆地的天然气主要来自油井伴生气,而油井的钻探和开发则受油价驱动。今年二叠纪盆地的天然气产量随着石油产量的增加而增加。

9 月份,尤蒂卡的页岩天然气产量为 56 亿立方英尺/天,比 2019 年 12 月的月高点 83 亿立方英尺/天低 33%,比 2023 年的平均产量 62 亿立方英尺/天低 10%。尤蒂卡位于马塞勒斯下方,深度为 5,000 英尺至 11,000 英尺,由于深度较深,钻井成本比马塞勒斯井略高。

深度为 10,500 英尺至 13,500 英尺的海恩斯维尔井的钻井成本甚至更高。2024 年 9 月,海恩斯维尔的页岩天然气产量为 13.0 亿立方英尺/天,比 2023 年 5 月的峰值低 14%。海恩斯维尔是美国第三大页岩气产区,仅次于马塞勒斯和二叠纪。2023 年,海恩斯维尔的页岩天然气产量平均为 14.6 亿立方英尺/天,占美国干天然气总产量的 14%。

美国基准亨利中心天然气价格从 2022 年 8 月经通胀调整后的高点 9.39 美元/百万英热单位 (MMBtu) 下跌 79% 至 2024 年 8 月的平均 1.99 美元/MMBtu。今年迄今为止,价格平均为 2.10 美元/MMBtu,而 2022 年经通胀调整后的平均价格为 6.89 美元/MMBtu,2023 年为 2.62 美元/MMBtu。随着天然气价格下跌,在干气层中生产天然气的经济性恶化,导致生产商关闭生产并减少钻井平台。

随着天然气价格波动,生产商往往会增加或减少在运行的钻井平台数量。贝克休斯的数据显示,自 2022 年底以来,海恩斯维尔、尤蒂卡和马塞勒斯地区的天然气定向钻井平台数量一直在稳步下降。在海恩斯维尔,2024 年 9 月平均有 33 座钻井平台在运行,比 2023 年 1 月减少了 53%。9 月份海恩斯维尔地区在运行的钻井平台数量是自 2020 年 7 月以来的最低水平。

在尤蒂卡,2024 年 9 月平均有 7 座钻机在运营,不到 2023 年 1 月运营数量的一半;在马塞勒斯,平均有 25 座钻机在运营,比 2023 年 1 月减少约 36%。虽然近年来新井的生产力有所提高,但钻机数量的下降导致整体产量下降。

美国能源信息署在其最新的《短期能源展望》中预测,2024 年美国干天然气总产量平均为 1035 亿立方英尺/天,略低于 2023 年的 1038 亿立方英尺/天,并将在 2025 年恢复小幅增长,​​达到 1046 亿立方英尺/天。

EIA reports decline in 2024 U.S. shale natural gas production

October 24, 2024

(WO) — U.S. natural gas production from shale and tight formations, which accounts for 79% of dry natural gas production, decreased slightly in the first nine months of 2024 compared with the same period in 2023, according to a report by the U.S. Energy Information Administration (EIA). If this trend holds for the remainder of 2024, it would mark the first annual decrease in U.S. shale gas production since the EIA started collecting these data in 2000.

Total U.S. shale gas production from January through September 2024 declined by about 1%, to 81.2 billion cubic feet per day (Bcf/d), compared with the same period in 2023, while other U.S. dry natural gas production increased by about 6% to 22.1 Bcf/d. Total U.S. dry natural gas production from January through September 2024 averaged 103.3 Bcf/d, essentially flat compared with the same period in 2023.

The decline in shale gas production so far this year has been driven primarily by declines in production in the Haynesville and Utica plays. From January through September 2024, shale gas production decreased by 12% (1.8 Bcf/d) in the Haynesville and by 10% (0.6 Bcf/d) in the Utica compared with the same period in 2023. At the same time, shale gas production in the Permian play grew by 10% (1.6 Bcf/d). Production in the Marcellus play, which leads U.S. shale gas production, remained flat.

The Haynesville play in northeastern Texas and northwestern Louisiana is a dry natural gas formation. The Utica and Marcellus plays in the Appalachian basin produce lease condensate in addition to dry natural gas. In all three plays, natural gas prices mostly drive drilling and developing wells. The U.S. benchmark Henry Hub daily natural gas price has generally declined since August 2022 and reached record lows in the first half of 2024, making drilling natural gas wells less profitable, particularly in the Haynesville. Several operators in the Haynesville and the Appalachian basin shut in natural gas production in reaction to historically low prices and intend to continue curtailments in the second half of 2024.

In contrast, natural gas produced in the Permian play in western Texas and southeastern New Mexico is primarily associated gas from oil wells where drilling and development is driven by the oil price. Natural gas production in the Permian has increased this year along with increasing oil production.

Shale natural gas production in the Utica was 5.6 Bcf/d in September, 33% less than the monthly high of 8.3 Bcf/d in December 2019 and 10% less than the average of 6.2 Bcf/d in 2023. At depths of 5,000 feet to 11,000 feet, wells in the Utica, which lies beneath the Marcellus, are slightly more expensive to drill than Marcellus wells because of their depth.

Drilling costs of Haynesville wells, at depths of 10,500 feet to 13,500 feet, are even higher. Shale natural gas production in the Haynesville was 13.0 Bcf/d in September 2024, 14% less than the peak in May 2023. The Haynesville is the third-largest shale gas-producing play in the United States, behind the Marcellus and the Permian plays. In 2023, shale natural gas production in the Haynesville averaged 14.6 Bcf/d, accounting for 14% of total U.S. dry natural gas production.

The U.S. benchmark Henry Hub natural gas price fell 79% from the August 2022 inflation-adjusted high of $9.39 per million British thermal units (MMBtu) to an average of $1.99/MMBtu in August 2024. So far this year, the price has averaged $2.10/MMBtu compared with an inflation-adjusted average of $6.89/MMBtu in 2022 and $2.62/MMBtu in 2023. As natural gas prices declined, the economics of producing natural gas in the dry gas formations worsened, leading producers to shut in production and drop drilling rigs.

Producers tend to increase or decrease the number of drilling rigs in operation as natural gas prices fluctuate. The number of natural gas-directed drilling rigs in the Haynesville, Utica, and Marcellus plays has decreased steadily since the end of 2022, according to data from Baker Hughes. In the Haynesville, an average of 33 rigs were in operation in September 2024, 53% fewer than in January 2023. The number of rigs operating in the Haynesville in September was the lowest it has been since July 2020.

In the Utica, an average of seven rigs were operating in September 2024, fewer than half the number that were operating in January 2023, and in the Marcellus, an average of 25 rigs were in operation, about 36% fewer than in January 2023. Although the productivity of newer wells has improved in recent years, the decline in rig counts has contributed to an overall decrease in production.

In their latest Short-Term Energy Outlook, the EIA forecasted total U.S. dry natural gas production to average 103.5 Bcf/d in 2024, down slightly from 103.8 Bcf/d in 2023, and to resume modest growth in 2025 at 104.6 Bcf/d.
