美国石油产量创纪录的秘密?钻井效率提升IA

据美国能源情报署报道,尽管钻机数量大幅下降,但水平钻井和水力压裂技术的进步正在使美国的油井变得更加高效。

尽管全国盆地钻探活动下降,美国原油产量却达到创纪录水平。

2023 年 12 月,美国原油产量平均为 13.3 百万桶/日,超过了 2019 年 11 月约 13 百万桶/日的疫情爆发前高点。

尽管由于水平钻井和水力压裂技术的进步,美国的钻井和完井活动有所下降,但产量仍达到了创纪录的水平。

根据美国能源情报署的说法,这违背了典型的规范;从历史上看,通过钻探活动上线的新井数量一直是原油产量增加或减少的关键决定因素。

但与之前的商品周期相比,美国生产商如今钻探的油井更长、效率更高。勘探与生产公司正在从新钻探井和已生产一年多的旧井中提取更多石油。

EIA 3 月 5 日报告称,“自 2021 年以来,传统产量份额保持稳定,新井产量持续增加”。

更少的井、更长的支管、更少的资金

美国生产商努力维持石油和天然气产量,同时减少钻探新井的资金。

根据贝克休斯公司的最新数据,截至 3 月 1 日当周,美国有 629 座活跃钻井平台,其中包括 608 座陆上钻井平台和 21 座海上钻井平台。

这比去年同期美国各地的 732 座钻井平台总数下降了 16%。

活跃石油钻井平台数量为 506 个,比去年同期的 592 个活跃石油钻井平台减少 15%。

由于 COVID-19 的低迷,每年钻探的新油井的增长也有所下降。

由于疫情对经济的影响,2020 年新演习数量减少了近 40%,至 7,147 次。从那时起,每年上线的新井数量与新冠疫情之前相比有所放缓。

EIA 写道:“2022 年,新原油井数量与 2017 年持平。” “2023年上半年,钻井公司新钻井数量比2022年同期增加了12%(624口井)。”

2014年新增油井数量达到峰值13,745口。

Siebert Williams Shank董事总经理 Gabriele Sorbara表示,石油和天然气行业受益于运营效率,例如改进完井设计、执行更大的项目、钻探更长的横向长度以及优化资本支出分配。

二叠纪盆地几家最大的石油生产商,包括埃克森美孚公司西方石油公司响尾蛇能源公司、二叠纪资源公司OvintivCivitas Resources 公司,今年的目标是通过钻探更长的支管来提高钻完井 (D&C) 效率。

Sorbara 表示,油田服务通胀也在下降,这有助于降低生产商的 D&C 成本。

The Secret to Record US Oil Output? Drilling Efficiencies—EIA

Advances in horizontal drilling and fracking technologies are yielding more efficient oil wells in the U.S. even as the rig count plummets, the Energy Information Administration reported.

U.S. crude oil production is reaching record levels in the face of declining drilling activity in basins across the nation.

U.S. crude output averaged 13.3 MMbbl/d in December 2023, passing the pre-pandemic high of roughly 13 MMbbl/d in November 2019.

Record output was achieved even as U.S. drilling and completion activity declined because of advances in horizontal drilling and fracking technologies.

That bucks the typical norm, according to the U.S. Energy Information Administration; historically, the number of new wells brought online through drilling activity has been the key determinant of whether crude output increases or decreases.

But U.S. producers are drilling longer and more efficient wells today than in previous commodity cycles. E&Ps are extracting more oil from both new wells drilled and legacy wells that have produced for more than a year.

“The share of legacy production since 2021 has remained stable, and production from new wells has continued to increase,” the EIA reported on March 5.

What's Affecting Oil Prices This Week? (March 4, 2024)


Fewer wells, longer laterals, less money

U.S. producers have worked to maintain oil and gas output while spending less money to drill new wells.

There were 629 drilling rigs active around the U.S.—including 608 onshore rigs and 21 offshore rigs—during the week ended March 1, according to the most recent data from Baker Hughes Co.

That’s down 16% from 732 total rigs around the U.S. during the same period a year ago.

The number of active oil-directed rigs was 506, down 15% from 592 active oil rigs during the year-ago period.

The growth of new oil wells drilled each year has also declined emerging from the COVID-19 downturn.

New drills fell by nearly 40% in 2020 to 7,147 due to the economic impact from the pandemic. Since then, the number of new wells coming online each year has slowed compared with pre-COVID rates.

“In 2022, the number of new crude oil wells was the same as in 2017,” the EIA wrote. “In the first half of 2023, drillers increased the number of new wells by 12% (624 wells) compared with the same period in 2022.”

The number of new oil wells peaked at 13,745 in 2014.

The oil and gas sector has benefitted from operational efficiencies like improving completion designs, executing larger projects, drilling longer lateral lengths and refining capex allocation, said Siebert Williams Shank Managing Director Gabriele Sorbara.

Several of the largest oil producers in the Permian Basin, including Exxon Mobil Corp., Occidental Petroleum, Diamondback Energy, Permian Resources, Ovintiv and Civitas Resources, aim to drive greater drilled and completed (D&C) efficiencies this year by drilling longer laterals.

Oilfield service inflation, which plagued the upstream sector emerging from the COVID downturn, is also declining, which helps bring down D&C costs for producers, Sorbara said.
