DUG 阿巴拉契亚:切萨皮克喜欢其双盆地投资组合

切萨皮克能源公司旗下的马塞勒斯页岩油和海恩斯维尔页岩油“截然不同”,但它们仍然作为勘探与生产天然气业务的补充部分结合在一起。

随着数十亿美元的交易宣布和新的并购传闻似乎每天都在传出,切萨皮克能源公司在经历了一年忙碌的资产出售以求变得更加强劲之后,并没有陷入狂热之中。

2021 年,摆脱破产困境,切萨皮克开始打造专注于马塞勒斯页岩和海恩斯维尔页岩的双盆地投资组合。该战略包括剥离大多数其他盆地的资产,特别是今年早些时候通过三笔独立交易退出 Eagle Ford 页岩,价值约 35 亿美元

“当我回顾一下我们围绕我们的投资组合所做的选择时,我们在并购领域非常活跃。“我们非常努力地重新定位公司的投资组合,而且我们在完成这一工作时充满了信心,以至于我们对自己所处的位置感到非常满意,”切萨皮克执行副总裁 Josh Viets 说道。总裁兼首席运营官于 11 月 30 日在匹兹堡举行的哈特能源DUG 阿巴拉契亚会议上说道。

因此,切萨皮克并没有感受到任何走出去收购更多资产的压力,他说。任何交易都必须与公司的顶级库存竞争。

“到目前为止,我们所做的事情确实增强了公司的实力,并为我们走出去做其他事情创造了一个非常高的门槛,”他说。

他说,任何潜在的收购都必须让公司变得更好,而不仅仅是更大,才能被考虑。

“我们很高兴坐在这里开发我们今天拥有的资产,”越南说。

塑造投资组合

破产后,切萨皮克选择出售其在粉河盆地的“极其复杂”的资产以及其在 Eagle Ford 的资产,其中其破产前最后的收购之一是 2019 年收购石油生产商 WildHorse Resource开发公司斥资 40 亿美元。

在公司重组之后,选择将资本支出花在哪里成为切萨皮克越来越棘手的决定。

“当您开始降低库存曲线,并且您还不确定是否要投资或投资与资产所需的剩余位置相同时,您就需要决定是继续投资和分配资本,或者当资产开始下降时停止投资,这从来都不是一个好的选择,”他说。 

切萨皮克肯定想投资的是两个“截然不同”但互补的盆地——马塞勒斯和海恩斯维尔。

“我认为这是公司可以拥有的最简单的资产之一,我知道我们的一些技术人员会说,这并不总是正确的,但一切都是相对的,”Viets 谈到 Marcellus 时说道。“它具有相对较低的成本结构,它的下降率相对较低。它拥有一个非常宽容的水库,可以与北美最好的页岩岩相媲美。”

但尽管有诸多好处,阿巴拉契亚盆地也并非没有挑战,最明显的是基础设施的限制。他说,基础设施的建设本身就具有挑战性,特别是当它必须跨越多个州界时。

“这是我们如此看好路易斯安那州地位的原因之一,因为一切都在该州范围内,”他谈到切萨皮克在海恩斯维尔的资产时说道。

然而,曾在美国和加拿大许多非常规盆地工作过的 Viets 表示,海恩斯维尔的地质特征与马塞勒斯的简单特征截然不同。 

海恩斯维尔可能是北美正在开发的最复杂的非常规页岩气田。它很深,压力非常高。井口压力超过 8,000 psi 的情况并不罕见。您尝试在温度远高于 370 华氏度的水库中钻孔。生产过程中需要应对二氧化碳和硫化氢。所有这些都转化为更高的成本和更高的盈亏平衡,”他说。

他说,这可能很复杂,但它的位置很好,可以覆盖美国墨西哥湾沿岸的液化天然气基础设施。他说,这意味着不仅可以增加资产,还可以获得生产的溢价。

数据、技术和技巧

虽然切萨皮克公司已在美国大部分页岩盆地开展业务,但“从一开始”它就在马塞勒斯和海恩斯维尔开展业务,”Viets 说。该公司“在两个盆地都拥有一千多口井”。

他说,切萨皮克积累了大量数据,可以帮助为日常运营提供信息,特别是通过分析和机器学习。 

“我们能够获取海恩斯维尔马塞勒斯资产中的所有历史钻井参数,并允许我们帮助管理钻井计划的运营团队预测和估计渗透率 [ROP] 应该是多少他说,“我们要钻探接下来的一百英尺的支管。”

这很有用,因为它有助于建立机械钻速目标,而且还提供了设置参数的指导,例如实现所需机械钻速所需的钻压或压差。

这些技巧和技术正在取得成效。 

“自去年年底以来,我们今年钻井作业的每日进尺提高了 40%,这绝对是惊人的。我们在马塞勒斯钻探过的 10 口速度最快的井中,今年已经钻探了 8 口。当我们将油井成本与 2023 年初进行比较时,我们的油井成本下降了 20%,”Viets 说。

他说,支线正在变得越来越长,并指出在过去五年内,切萨皮克将马塞勒斯的支线长度增加了 70%。

“我们还实施了一种非常有创意的井眼轨迹设计,我们称之为混合式,[我们]“能够最大化横向长度,”他说。

DUG Appalachia: Chesapeake Likes its Dual-basin Portfolio

“Distinctly different,” Chesapeake Energy’s Marcellus and Haynesville shales have nevertheless fit together as complementary pieces of the E&P gas-focused holdings.

With billions in deals announced and new M&A rumors bouncing around seemingly day-to-day, Chesapeake Energy Corp. isn’t getting caught up in the furor after a busy year of selling off assets to get gassier.

In 2021 after emerging from bankruptcy, Chesapeake set about crafting a dual-basin portfolio concentrated in the Marcellus and Haynesville shales. The strategy included shedding assets in most other basins and, notably, exiting the Eagle Ford Shale earlier this year in three separate deals valued at about $3.5 billion.

“As I kind of walk through the choices that we’ve made around our portfolio, we’ve been very active in the space of M&A. We’ve worked really hard to reposition the company’s portfolio and we’ve done that with a level of conviction to the point that we feel really good about where we’re at,” Josh Viets, Chesapeake executive vice president and COO said during Hart Energy’s DUG Appalachia Conference on Nov. 30 in Pittsburgh.

As a result, Chesapeake doesn’t feel any pressure to go out and acquire more assets, he said. And any deal would have to compete with the company’s top-tier inventory.

“What we’ve done so far has really strengthened the company and it creates a really high bar for us to go out and do anything else,” he said.

To be considered, he said, any potential acquisition would have to make the company better, not just bigger.

“We’re pretty happy to sit here and develop the assets that we own today,” Viets said.

Shaping the portfolio

Post-bankruptcy, Chesapeake opted to sell off its “incredibly complex” assets in the Powder River Basin—as well as its Eagle Ford holdings, where one of its last pre-bankruptcy acquisitions was the 2019 purchase of oil producer WildHorse Resource Development Corp. for $4 billion.

In the aftermath of corporate reorganization, choosing where to spend capex became an increasingly thorny decision for Chesapeake.

“As you start to work down an inventory curve and you have remaining locations that you’re not quite sure you want to invest or invest as much maybe as what the asset needs, you’re left with the decision to either continue to invest and allocate capital or you stop investing when the asset starts to decline and that’s never a good choice,” he said. 

Where Chesapeake definitely wanted to invest were two “distinctly different” but complementary basins—the Marcellus and Haynesville.

“It's one of the simplest assets that I think a company could have, and I know some of our technical people will say that’s not always true, but everything’s relative,” Viets said of the Marcellus. “It has a relatively low-cost structure, it has relatively low decline rates. It has a very forgiving reservoir against some of the best shale rock that you’ll find here in North America.”

But for all the upside, the Appalachia Basin is not without its challenges, most notably infrastructure constraints. Infrastructure is inherently challenging to build, he said, particularly when it must cross multiple state lines.

“That’s one of the reasons we’re so bullish on our Louisiana position, because everything stays within the state,” he said of Chesapeake’s Haynesville holdings.

However, Viets, who has worked in many of the unconventional basins across the U.S. and Canada, said the Haynesville features a far different geology than the easy characteristics of the Marcellus. 

The Haynesville “is probably the most complicated unconventional shale gas field that is being developed across North America. It’s deep, it’s very high pressure. It’s not uncommon to have wellhead pressures over 8,000 psi. You’re trying to drill in the reservoir with temperatures that are well above 370 degrees Fahrenheit. You have CO2, you have H2S that you’re contending with on the production side. All of that translates into its higher cost with higher breakevens,” he said.

It may be complicated, but it’s well positioned to reach of LNG infrastructure on the U.S. Gulf Coast, he said. That means it’s possible not just to grow the asset, but also to receive premium pricing for the production, he said.

Data, tech and techniques

While Chesapeake has operated in most of the U.S. shale basins, it has been in the Marcellus and Haynesville “from the very beginning,” Viets said. And the company has “well over a thousand wells in both basins.”

Chesapeake has accumulated large amounts of data that can help inform daily operations, especially through analytics and machine learning, he said. 

“We’ve been able to take all of our historical drilling parameters within our Haynesville Marcellus assets and allow our operations teams that are helping manage our drilling programs to forecast and provide an estimate of what a rate of penetration [ROP] should be for the next … hundred feet of the lateral that we’re going to be drilling,” he said.

That’s useful because it helps establish a target for ROP, but it also provides guidance on setting parameters such as weight on bit or differential pressure that are needed to achieve the desired ROP.

And such techniques and technology are paying off. 

“Our footage per day on our drilling operations this year have been improved by 40% since late last year, which is absolutely phenomenal. Eight of the 10 fastest wells that we’ve ever drilled in the Marcellus have been drilled this year. As we compare our well costs to early in 2023, our well costs are down by 20%,” Viets said.

And laterals are getting longer, he said, noting that within the past five years, Chesapeake has increased Marcellus lateral lengths by 70%.

““We’ve also implemented a pretty creative wellbore trajectory design, which we call a hybrid, where [we’re] … able to maximize the lateral length,” he said.
