美国能源信息署：更长水平井推动二叠纪盆地原油和天然气产量增长
Longer wells boost Permian crude oil and natural gas production
美国能源信息署称，二叠纪盆地油气产量从2015年的每日290万桶油当量升至2025年的每日1120万桶油当量，增幅为284%。同期，新水平井平均侧钻长度增加77%，从6149英尺升至10867英尺；2025年，超过15000英尺的超长侧钻井占新完井井数的15%。自2022年以来，该地区每年新完井水平井数量基本维持在约6000口。

Well operators in the Permian region of western Texas and eastern New Mexico are getting more oil and gas out of the ground by drilling longer, horizontal wells and increasingly incorporating so-called super-lateral wells that exceed 15,000 feet.
The Permian region in western Texas and eastern New Mexico is one of the most prolific unconventional oil- and natural gas-producing regions in the world. Longer lateral wells allow operators to contact significantly more reservoir rock with each well, maximizing production while keeping well counts, and therefore overhead costs, down.
In 2015, short-reach wells measuring less than 5,000 feet were common; they made up 43% of the wells completed in 2015. By 2025, they accounted for just 4% of horizontal wells. As the short-reach well share plummeted, the share of new wells classified as mid-length laterals, those wells measuring between 5,000 feet and 15,000 feet, grew from 57% of completions in 2015 to a peak of 90% in 2021, before settling at 81% in 2025.
The slight reduction in the share of mid-length lateral wells in the past five years came amid the emergence of super-laterals; ultra-long wells exceeding 15,000 feet. Virtually nonexistent before 2020, these wells, more than three miles long, accounted for 15% of all new Permian well completions in 2025.
While the number of new wells being drilled has remained relatively stable, hydrocarbon production in the region has grown rapidly over the past decade, rising from 2.9 million barrels of oil equivalent per day (BOE/d) in 2015 to 11.2 million BOE/d in 2025—a 284% increase.
Outside of the unprecedented market disruptions in 2020 and 2021—when negative oil prices and uncertainty surrounding the COVID pandemic severely curtailed activity—new horizontal well completions in the Permian have consistently hovered around 6,000 per year since 2022. Meanwhile, the average lateral length of a new horizontal Permian well increased 77% in the last decade, rising from 6,149 feet in 2015 to 10,867 feet in 2025, based on data from Enverus.
