行业高管和分析师告诉路透社,过去两年美国页岩气区的生产力有所下降,生产商正在寻求部署新技术来扭转这些下降趋势,但小公司往往无法承担高昂的前期成本 

尽管页岩油生产推动美国原油产量在近几个月创下历史新高,达到每天 1300 万桶 (bpd) 以上,但自 2020 年以来,由于位置较近的油井的水力压裂干扰了地质和压力,导致生产率下降速度加快。资源开采更加困难。

 Enverus Intelligence Research (EIR)在 2023 年 8 月的一份报告中表示,过去十年来,美国页岩油区的石油产量下降趋势加剧。 

“我们观察到,随着密度的增加,下降曲线(即产量随时间下降的速度)变得越来越陡,”报告作者兼 EIR 董事总经理 Dane Gregoris 当时评论道。

“总结起来,行业跑步机正在加速,这将使产量增长比过去更加困难。”

 但美国能源信息署(EIA)上个月表示,水平钻井和水力压裂技术的进步在过去一年中提高了油井产能,帮助美国生产商从新钻的油井中提取更多原油,同时维持旧油井的产量。 

 美国压裂服务市场的领导者哈里伯顿表示,其中一项技术,同步压裂技术或同步压裂,与拉链压裂作业相比,可以在更短的时间内实现两倍以上的横向进尺增益。 

然而,同时压裂技术需要预先钻探大量井,然后同时进行压裂。在石油从油井中流出之前,这需要大量投资,但并非所有公司都能负担得起。

“在你看到任何收入之前,这已经是 1 亿美元了,”小公司 Tall City Exploration 的首席执行官迈克·奥斯特曼 (Mike Oestmann) 告诉路透社。

Oil Price


As well productivity in the U.S. shale patch has declined in the past two years, producers are looking to deploy new technology to reverse these declines, but small companies often cannot afford the high upfront costs, industry executives and analysts have told Reuters.

While shale production pushed U.S. crude oil output to record highs in recent months to above 13 million barrels per day (bpd), the rate of productivity declines has steepened since 2020 as the fracking of closely located wells has interfered with geology and pressure, resulting in more difficult extraction of the resources.

Oil decline profiles have steepened across U.S. shale oil plays over the last decade, Enverus Intelligence Research (EIR) said in a report in August 2023.

“We’ve observed that decline curves, meaning the rate at which production falls over time, are getting steeper as well density increases,” Dane Gregoris, report author and managing director at EIR, commented at the time.

“Summed up, the industry’s treadmill is speeding up and this will make production growth more difficult than it was in the past.”

But advances in horizontal drilling and hydraulic fracturing technologies have increased well productivity over the past year, helping U.S. producers extract more crude oil from new wells drilled while maintaining production from legacy wells, the U.S. Energy Information Administration (EIA) said last month.

One of these technologies, simultaneous fracking technology, or simul-frac, can achieve over double the gains in lateral footage, in less time, compared to zipper-frac operations, says Halliburton, the leader in the U.S. fracking services market.

The simul-frac tech, however, needs a lot of wells drilled beforehand and then fracked simultaneously. This requires a lot of investment before oil can flow from the wells—and not all companies can afford that.

“That’s $100 million in the ground before you see any revenue,” Mike Oestmann, chief executive at small company Tall City Exploration told Reuters.
