EIA:2024 年美国天然气钻井数量将连续第二年下降

根据美国能源信息署 (EIA) 的数据,过去两年来,美国部署的用于钻探天然气的钻井数量有所减少。2022 年 12 月至 2024 年 12 月期间,美国用于天然气的钻井数量减少了 32%(50 座钻井)。这种下降主要集中在天然气资源丰富的海恩斯维尔和阿巴拉契亚地区,这两个地区的天然气钻井总数在 2023 年下降了 34%(43 座钻井),在 2024 年下降了 24%(21 座钻井)。

钻井平台数量的下降与 2024 年大部分时间的天然气价格创历史新低以及先进钻井和完井技术的广泛采用相吻合。

在横跨德克萨斯州和路易斯安那州的海恩斯维尔地区,钻井成本往往高于其他地区,因为海恩斯维尔油井的钻井深度较大,通常在 10,500 英尺至 13,500 英尺之间。由于过去两年天然气价格普遍下降,自 2022 年 12 月(39 座钻井)以来,海恩斯维尔的钻井数量减少了 55%,因为钻井的经济性下降了。因此,海恩斯维尔地区的市场天然气产量在同一时期下降了 7%。

同样,在阿巴拉契亚地区,包括马塞勒斯和尤蒂卡地区生产的天然气,由于天然气价格下跌,自 2022 年 12 月(19 座)以来,钻井数量下降了 37%。因此,同期市场天然气产量的增长被限制在 4% 以内。

生产者对价格变化的反应程度取决于多种因素,例如未来价格、合同、市场波动和价格对冲的不确定性;材料、设备和劳动力的当前成本;以及运输和储存的可用性。

美国基准亨利港天然气价格在 2022 年达到 6.95 美元/百万英热单位的 14 年高点后,在 2023 年下跌 62%(4.31 美元/百万英热单位),在 2024 年进一步下跌 16%(0.43 美元/百万英热单位)。2024 年亨利港价格是经通胀调整后有史以来的最低价格,2024 年 3 月创下最低平均价格 1.51 美元/百万英热单位。

天然气资源丰富的地区的生产商通过减少钻井数量(钻井数量下降就是明证)甚至削减产量来应对持续低迷的价格,这导致已钻但未完工的油井库存增加。如果天然气需求和价格继续上涨,生产商可能处于更有利的经济地位来完成这些油井,从而有可能迅速提高产量。

EIA: US natural gas-directed rigs decreased for second consecutive year in 2024

Published by , Editorial Assistant
Oilfield Technology,


According to the US Energy Information Administration (EIA), the number of rigs deployed to drill for natural gas in the United States decreased over the last two years. US natural gas-directed rigs decreased 32% (50 rigs) between December 2022 and December 2024. This decline has been concentrated in the natural gas-rich Haynesville and Appalachia regions, where the combined natural gas rig count declined by 34% during 2023 (43 rigs) and by 24% during 2024 (21 rigs).

The decline in drilling rigs coincides with record-low natural gas prices for most of 2024 and the wider adoption of advanced drilling and completion technologies.

In the Haynesville region, which spans Texas and Louisiana, drilling costs tend to be higher than in other plays because Haynesville wells are drilled to greater depths, usually between 10 500 ft and 13 500 ft deep. As natural gas prices have generally declined over the last two years, rigs in the Haynesville have decreased 55% since December 2022 (39 rigs) as drilling has become less economical. Consequently, marketed natural gas production in the Haynesville region has declined 7% over the same period.

Similarly in the Appalachia region, which includes natural gas produced from the Marcellus and Utica plays, rigs have declined 37% since December 2022 (19 rigs) with the drop in natural gas prices. As a result, growth in marketed natural gas production has been limited to 4% over the same period.

The extent to which producers respond to price changes depends on several factors, such as uncertainty around future prices, contracts, volatility in the market, and price hedging; current costs of materials, equipment, and labour; and availability of transportation and storage.

After the US benchmark Henry Hub natural gas price reached a 14-year high of US$6.95/million Btu in 2022, it fell 62% in 2023 (US$4.31/million Btu) and a further 16% in 2024 (US$0.43/million Btu). The Henry Hub price in 2024 was the lowest ever reported after adjusting for inflation, with March 2024 marking the lowest average price of US$1.51/million Btu.

Producers in natural gas-rich regions have responded to these persistently low prices by drilling less – as reflected in the declining rig counts – and even by curtailing production, which has grown inventories of drilled but uncompleted wells. If natural gas demand and prices continue to rise, producers could be in a better economic position to complete these wells, potentially allowing them to quickly increase production.
