汇丰银行 最近的预测 显示,美国页岩油产量将在未来四年内持续增长,然后达到峰值,但实际情况要复杂得多。伍德麦肯兹强调, 页岩油效率提升的新时代已经 到来,但这些进步伴随着巨大的成本,可能会阻碍未来的增长。尽管去年,受意外的效率提升推动,日产量增加了 100 万桶,但这种增长的可持续性还远未得到保证。

页岩气冲击

去年,美国页岩油行业在钻井数量持续下降的情况下,产量却超出了预测者的预期,这让几乎所有人,甚至一些业内人士都感到惊讶。

增长的原因之一是油价,2023 年初油价仍然处于高位。另一个重要原因是钻井工人迫切希望尽其所能提高钻井效率。

由美国本土 48 个州研究主管玛丽亚·皮科克 (Maria Peacock) 撰写的 Wood Mackenzie 报告指出,几年前,由于页岩钻井作业分散在较大的区域,新的效率提升不可能实现。现在,它们变得更加集中,为减少停机时间等改进创造了机会。

事实上,皮科克认为,减少停机时间是美国页岩气新效率时代的一个主要特征。她写道:“虽然技术进步具有变革性,但最大的进步来自于消除停机时间。”

与此同时,水力压裂法变得更快、更便宜,水平段变得更长,更富有的公司开始同时对多个油井进行水力压裂。所有这些都有助于提高产量,同时也降低了油井的产能。

路透社 4 月份援引 Enverus 数据报道称,二叠纪盆地的油井生产率  自 2020 年以来下降了 15%。考虑到页岩油储层的性质和水力压裂的性质,这并不完全是意外的发展。事实上,与传统油井相比,页岩油井的枯竭速度更快,这经常被反向分析师引用作为他们看好油价的原因。然而,美国的产量却一直在继续上升。

同步压裂

这似乎造成了这样一种印象:由于不断提高效率和降低成本,无论国际价格如何,美国原油产量都将永远以同样的速度增长。然而,效率的提高是有代价的,这个代价就是生产成本的增加和油井生产率的下降。事实上,成本的增加部分是由于油井生产率的下降。

例如,那些较长的水平段是为了应对生产率下降而采取的措施。他们努力扭转这一局面,但这也使得钻井成本更高。所谓的“同步压裂”是指钻一组井,然后同时对它们进行水力压裂以提高采收率,这种做法的前期成本比钻井和水力压裂单个井要高得多。

所有这些表明,就像能源转型一样,总是存在着权衡。这也表明,承认这种权衡(更高的效率和更高的产出,更高的成本)是更明智的做法,而不是假装它不存在,只选择积极的一面。

然而,正是由于这些权衡,二叠纪盆地和其他页岩油田的效率爱好者可能会对产量增长保持谨慎。诚然,2023 年他们增加的石油桶数超出了任何人的预期,但这并不意味着今年的情况会重演——尤其是在油价低于 2023 年的情况下。尤其是在并购浪潮尚未消退之后。

合并热潮

过去 12 个月,页岩油生产商达成了价值约 2000 亿美元的交易,而且交易仍未结束。今年第一季度,  石油行业的并购活动 创下历史新高,交易价值达 500 亿美元。随后,在第二季度,康菲石油公司以 225 亿美元的价格 收购了马拉松石油公司,这表明交易势头仍然强劲。

这种势头使得页岩油行业不再那么拥挤。行业越不拥挤,影响其发展方向的决策者就越少。换句话说,与几年前相比,现在页岩油产量增长率掌握在更少的高管手中。

这是又一个自然过程——以整合作为增长手段——在经历了多年的爆炸式增长后,未开发和未出租的土地几乎已经用完了。但这一自然过程,就像油井生产力的变化和效率的提高一样,使页岩油产量的未来增长率变得不确定,而不是像一些分析师所说的那样有保证。

如果说近期的页岩历史教会了我们什么,那就是永远不要妄下结论。仅仅因为效率提升在 2023 年推动了产量增长,并不意味着今年的产量增长会重演。仅仅因为这些效率提升使得钻井成本更高,并不意味着钻井人员不会再次找到削减成本的方法。最终,虽然 2023 年效率驱动的产量增长令人印象深刻,但页岩行业真正的考验将是如何在成本上升和市场动态不断变化的情况下保持增长。

Oil Price


HSBC’s recent forecast suggests U.S. shale oil production will keep rising for another four years before peaking, but the real story is more complex. Wood Mackenzie highlights a new era of efficiency gains in shale, yet these advancements come with significant costs that could hinder future growth. Despite last year’s impressive 1 million barrels per day increase, driven by unexpected efficiency improvements, the sustainability of such gains is far from guaranteed.

Shale Shocked

Last year, the U.S. shale industry surprised pretty much everyone, possibly even some within its circles, by boosting production more than forecasters expected amid a consistent decline in rig numbers.

One of the reasons for this growth was the price of oil, which was still comfortably high in the early months of 2023. The other big reason was a new urge among drillers to make their drilling more efficient however they could.

The Wood Mac report, authored by the research director for the Lower 48, Maria Peacock, notes that the new efficiency gains would not have been possible just a few years ago because shale drilling operations were scattered over larger areas. Now, they have become more clustered, opening up opportunities for improvements such as downtime reduction.

Indeed, downtime reduction is, according to Peacock, a major feature of the new efficiency era in U.S. shale. “While tech improvements have been transformative, the greatest advances have come from eliminating downtime,” she wrote.

Fracking, meanwhile, has become faster and cheaper, laterals have become longer, and richer companies have started fracking several wells simultaneously. All this has helped with the production boost—and with declining well productivity.

Well productivity in the Permian, as Reuters reported back in April, citing Enverus data, has shed 15% since 2020. This was not exactly an unexpected development, given the nature of shale oil reservoirs and the nature of fracking. In fact, the faster well depletion in shale as compared with conventional oil wells has often been cited by contrarian analysts as the reason for their bullish outlook on oil prices. And yet, U.S. output has just continued rising.

SimulFrac

This seems to have created the perception that U.S. crude oil output will continue to rise at the same pace for all eternity, regardless of international prices, because of the constant drive to boost efficiencies and reduce costs. However, the efficiency boosts have come with a price, and that price is higher production costs on top of the decline in well productivity. In fact, the higher costs have come in part because of that decline in well productivity.

Those longer laterals, for instance, were a response to declining productivity. They worked to reverse it, but this made well drilling costlier. The so-called simulfrac, which involves drilling a swarm of wells and then fracking them simultaneously to improve recovery rates, costs a lot more upfront than drilling and fracking individual wells.

What all this suggests is that, like in the energy transition, there is always a trade-off. It also suggests it is wiser to acknowledge this trade-off—better efficiencies and higher output at higher costs—rather than pretending it does not exist and cherry-picking only the positives.

However, it is because of these trade-offs that efficiency fans in the Permian and the rest of the shale patch are likely to remain guarded with production growth. Granted, 2023 saw them add more barrels than anyone expected, but this does not guarantee a repeat of the situation this year—especially with prices lower than they were in 2023. And especially after the wave of mergers and acquisitions that has not ebbed yet.

Merger Mania

Shale players closed deals worth some $200 billion in the past 12 months, and they’re not finished yet. The first quarter of the year saw record M&A activity in the oil patch, with deals worth $50 billion. Then, in the second quarter, Conoco inked a deal to buy Marathon Oil for $22.5 billion, signaling that the momentum was still strong in dealmaking.

This momentum is making shale oil a less crowded place. The less crowded an industry, the fewer people will be making decisions that affect its direction. In other words, the production growth rate in the shale patch is now in the hands of fewer executives than just a few years ago.

This is yet another natural process—consolidation as a means of growth—in an environment where untapped and unleased acreage has pretty much run out after years of explosive growth. But this natural process, just like well productivity changes and efficiency gains, makes future growth rates in shale oil production uncertain rather than guaranteed, as some analysts like to present them.

If recent shale history has taught us anything, it is to never make assumptions. Just because efficiency gains boosted production in 2023, it does not mean the boost will be repeated this year. And just because these efficiency gains have made drilling more expensive, it doesn’t mean drillers won’t find a way to cut costs again. Ultimately, while 2023’s efficiency-driven production boost was impressive, the true test for the shale industry will be maintaining growth amid rising costs and evolving market dynamics.
