洞中粉末:德文郡可能在未来几年启动其 PRB

德文能源公司正在完善怀俄明州粉河盆地油气藏的间距和完井方案,以便可能在本世纪末实现全油田开发。

德文能源公司可能计划在本世纪末将其位于怀俄明州的 Powder River Basin 项目转变为开发模式。

E&P 公司在多地层盆地中持有叠层油层,主要在尼奥布拉勒 (Niobrara) 着陆水平井,此外还在 Turner、Parkman 和 Teapot 地层进行勘探。

德文郡首席运营官克莱·加斯帕 (Clay Gaspar) 在 8 月份的财报电话会议上告诉投资者和证券分析师:“我们只是想把它作为我们投资组合中真正有价值的一部分,但它在我们的股价中可能没有任何价值。”

根据德文郡最新的季度报告,该公司第二季度该盆地的产量为 18,000 桶油当量/天,其中包括 13,000 桶油当量/天,占全公司桶油当量/天产量的 2%。

其大部分产量来自特拉华盆地,第二季度平均产量为 461,000 桶油当量/天,其中包括 221,000 桶/天的石油、121,000 桶/天的 NGL 和 712 百万立方英尺/天。

其第二季度产量平衡来自鹰福特页岩(79,000 桶油当量/天)、阿纳达科盆地(84,000 桶油当量/天)和威利斯顿盆地(61,000 桶油当量/天)。

“我希望随着时间的推移——也许是本世纪下半叶——火药将会有更多的机会真正介入,”加斯帕说。

“与此同时,在本世纪头五年,我们确实需要确保我们已经为此做好了准备,我今天要向你们传达的信号是,我们对所看到的稳步进展感到非常高兴。”

整个行业都已经开始热起来了。根据怀俄明州石油和天然气保护委员会和其他州能源委员会的数据,今年上半年,怀俄明州的获批油井数量几乎与科罗拉多州持平,远远超过北达科他州和俄克拉荷马州。

怀俄明州共计获得 508 口井许可,仅次于科罗拉多州的 512 口。根据德克萨斯铁路委员会的数据,德克萨斯州则以 3,186 口井的许可数量遥遥领先。

怀俄明州的法规中存在“许可竞相争夺”的异常现象,导致数千张许可证可以永久续期,从而导致非法占用。

2020 年颁布的新规定导致许可证数量仍然高于真实的钻探意向,但数量已大幅减少。 

“针移者”

德文郡第二季度在 Powder 业务的资本支出为 5300 万美元,而其整个投资组合中 E&P 业务的总支出为 8.96 亿美元。

目前,该公司正在继续借鉴特拉华州和其他油田的最佳实践,然后在其单钻机和半时压裂扩展 Powder 野猫作业中进行测试。

“好消息是我们将能够借助特拉华盆地和其他更加成熟和发达的强大盆地,同时释放 Powder 的潜力,”加斯帕说。

生产率、间距和完井工作仍在继续。一种新的套管设计“刚刚应用,节省了大量成本。”

到目前为止,它“提高了生产率,并继续增强了我们对这项资产的信心,”加斯帕说。

下一步是破解开发间距的密码“跨越一个非常大的航道”,除了降低成本。

但到目前为止,德文郡已经看到了一些进步,“这些进步正逐渐成为推动力”。

寻找“越过栅栏”

加斯帕说,在怀俄明州扩大规模后,成本应该会下降。

“我百分之百确信,成本将大幅下降,这是基于我们曾经作业过的每一个盆地(德文郡所见)的经验。”

但是,目前 Powder 的全部潜力仍被埋在地下 — — 直到我们达到 [规模]。这就是先有鸡还是先有蛋的难题。”

与此同时,德文正在收集盆地内的情报,他说,透过篱笆观察邻居们的钻井和完井方案和结果。

“有几家公司开展了更多的活动,我们也可以推断出从其他盆地获得的经验,从而有信心地了解其潜力,而这将真正开始发挥更大的作用。”

但他补充道,德文还有时间。

“时间对我们有利。我们有长期租约。我们有大量库存,可以让我们及时降低这一风险。”

加斯帕表示,不会出现“突然”的资本涌入 Powder 的情况。“我们将继续以非常系统的方式降低风险并释放潜力。”

德文的资本支出主要用于其特拉华盆地资产。“其中很大一部分仍“准备就绪”。

Powder in the Hole: Devon May Fire up its PRB in Coming Years

Devon Energy is perfecting its spacing and completion recipe in Wyoming’s Powder River Basin  play to possibly unleash full-field development later this decade.

Devon Energy may look to convert its Powder River Basin play in Wyoming to development mode later this decade.

The E&P holds stacked pay in the multi-formation basin where it’s landing laterals primarily in the Niobrara, in addition to prospecting in the Turner, Parkman and Teapot formations.

The leasehold is mostly locked up by Devon, EOG Resources, Continental Resources and Occidental Petroleum.

“I just want to keep it on your horizon as a really valuable piece of our portfolio that probably has zero value out there in the world [in] our share price,” Clay Gaspar, Devon COO, told investors and securities analysts in its August earnings call.

Devon’s second-quarter production from the basin was 18,000 boe/d, including 13,000 bbl/d of oil, or 2% of companywide boe/d of volume, according to its most recent quarterly report.

Most of its output came from the Delaware Basin that averaged 461,000 boe/d in the second quarter, consisting of 221,000 bbl/d of oil, 121,000 bbl/d of NGL and 712 MMcf/d.

The balance of its second-quarter output was from the Eagle Ford Shale (79,000 boe/d), Anadarko Basin (84,000 boe/d) and Williston Basin (61,000 boe/d).

“What I would expect in time—maybe the second half of the decade—[is] there will be more of an opportunity for the Powder to really step in,” Gaspar said.

“In the meantime in the front half of the decade, we really need to make sure that we're ready for that and what my signal to you today is we're really pleased with that steady progress that we're seeing.”

Industry-wide, the basin already is heating up. In the first half of the year, Wyoming nearly matched Colorado for the most permitted wells, well ahead of North Dakota and Oklahoma, according to the Wyoming Oil and Gas Conservation Commission and other state energy commissions.

Wyoming counted 508 wells permitted, just behind 512 in Colorado. Texas, of course, easily led the way with 3,186 wells, according to the Texas Railroad Commission.

Wyoming had a "race to permit" anomaly in its rules that resulted in thousands of permits that could be renewed in perpetuity, resulting in squatting.

The new rule, enacted in 2020, has resulted in a permit count that is still higher than true intentions to drill, but the count is substantially reduced. 

‘Needle-movers’

Devon’s second-quarter capex in the Powder was $53 million of its total $896 million spend on E&P operations across its portfolio.

Currently, it is continuing to take best practices from the Delaware and its other plays, and then testing them in its one-rig and half-time-frac-spread Powder wildcatting.

“The great news is we're going to be able to ride the back of the Delaware Basin and the other really strong basins that are much more mature and developed while we unlock the potential in the Powder,” Gaspar said.

Work is continuing on productivity, spacing and completion. A new casing design “we just applied is a very material cost savings.”

To date, it’s “resulted in higher productivity and has continued to bolster our confidence in this asset,” Gaspar said.

The next step is to crack the code on development spacing “across a very large fairway,” in addition to reducing costs.

But, so far, Devon has seen improvements “that are shaping up to be needle-movers.”

Looking ‘over the fence’

Upon scaling it up in Wyoming, costs should decline, Gaspar said.

“There’s 100% certainty in my mind that … costs are going to come down materially, and that's on the back of [what Devon has seen in] every other basin we've ever worked in.”

But the Powder’s full potential remains in the ground for now “until we get that [scale]. That's the chicken-and-egg conundrum.”

Meanwhile, Devon is picking up intelligence in the basin, looking “over the fence,” he said, at neighbors’ drilling and completion recipes and results.

“A couple of companies have a little bit more activity, and we can [also] extrapolate our learnings from the other basins to allow with certain confidence what the potential can be, and that will really start to play a bigger part.”

But, he added, Devon has time.

“Time is on our side. We have long-term leases. We have a great inventory that allows us to de-risk this play in time.”

There won’t be “a sudden … rush of capital towards the Powder,” Gaspar said. “We’ll continue to de-risk this and unlock this potential in a very systematic way.”

Devon’s capex is largely targeted to its Delaware Basin property. “There's a big chunk of that that's still … ready to go.”
