      哈特能源公司执行总编辑尼萨·达邦 (Nissa Darbonne):大家好。感谢您加入我们。我是哈特能源公司执行总编辑尼萨·达邦 (Nissa Darbonne)。我正在拜访蒂姆·比尔德 (Tim Beard)。蒂姆是 Expand Energy(新合并的切萨皮克和西南能源公司)的钻井副总裁。蒂姆,感谢您加入我们。

      Expand Energy 钻井副总裁蒂姆·比尔德 (Tim Beard):谢谢您的邀请。

      ND:Tim 是今天上午在匹兹堡DUG Appalachia的演讲者之一。Tim,我们在台上讨论了很多钻井和完井问题。我想特别关注的三个领域是:首先,Expand 显然一直在进行 DUC 和推迟 TIL,并通过节流阀削减一些现有油井。Expand 现在在该计划中处于什么位置?

      TB:是的。这个问题问得很好。我们有大约 80 个延期 TIL。所以延期 TIL 已经钻探完成。它已经完工。我们只是还没有将其投入使用。所以我们有大约 80 口这样的井。所以大约 10 亿立方英尺/天的产量是井口后面的。

      目前,我们拥有大约 60 个 DUC,并且一直在削减。这个数字会根据价格波动。我认为,目前我们在全国范围内削减了几百 [MMcf],无论是阿巴拉契亚,即我们的西南阿巴拉契亚资产,还是东北阿巴拉契亚资产或海恩斯维尔。

      这三个地区都拥有一定量的天然气(就西南阿巴拉契亚地区而言是液体),目前正在削减这些资源。

      ND:您提到了海恩斯维尔。你们在海恩斯维尔和阿巴拉契亚盆地都有业务。原海恩斯维尔的一位海恩斯维尔运营商在休斯顿北部的原海恩斯维尔/博西尔项目上取得了极大的进展,并建造了一些令人难以置信的油井。但这些油井也非常深、压力超高、温度超高。你们有没有研究过这个项目,看看是否有可以应用到你们的项目中?

      TB:是的,绝对如此。所以我们一直在关注情况,正如我在另一个房间里所说的那样,我认为如果所有操作员不向其他人学习,不关注情况,不从地质角度和/或从操作角度看他们在做什么,他们就是失职的。所以我们一直在关注他们在做什么。

      我认为他们不仅从生产角度看到了巨大的成果,而且他们开始降低 [D&C] 的价格。如果你看看这些油井的成本,就会发现目前成本有点高,10,000 英尺水平井每英尺成本上下浮动 3,000 美元。我们很快就能算出这个数字。这些油井很贵。

      但正如我们之前所说,从生产角度来看,它们的表现非常出色。因此,随着大宗商品价格上涨,该地区可能会继续受到越来越多的关注。随着中游公司进入该地区并能够将天然气运出该地区,这对在那里工作的人来说也是一件大事。

      但它对我们有什么影响?显然,我们从地质角度关注。我们需要朝那个方向发展吗?其次,从温度和压力的角度来看,情况非常极端,这些人不得不学习如何钻井、如何完井、如何生产这些油井。

      好消息是,整个行业的人都会找到解决方法。我们已经看到了这一点。

      我们今天早上谈了一下非常短的水平段,对吧?当我们钻到一英里时,我们认为我们做得很好。现在我们要钻五英里的水平段。

      但当我回想起海恩斯维尔时,那里的温度超过了 400 华氏度。压力高得令人难以置信。因此服务公司必须参与其中,他们已经开发出可以处理这些极端条件的工具。

      因此,当他们开发出这些工具时,我们就可以将它们带到海恩斯维尔的路易斯安那州一侧,那里的条件没有那么恶劣——仍然非常热,仍然压力很大,但与他们在德克萨斯州所做的相比,略有不同。

      这会让我们变得更好。我们已经看到了一些成果,我们在海恩斯维尔的效率在不断提高,从热孔的角度来看,我们使用的一些技术来自他们在德克萨斯州东部所做的一些工作。

      ND:此外,在改进方面,Expand 的两个前身之一切萨皮克 (Chesapeake) 是较早的——也是第二个实现 U 型转弯的油井。那实际上是在 Eagle Ford……现在在您运营的原始 Haynesville 有三个,但 Expand 对阿巴拉契亚的 U 型转弯感兴趣吗?

      TB:是的。如果我们在未来几年不钻一些 U 形井,我会感到惊讶。而钻 U 形井的“原因”不仅仅是为了耍小聪明钻一个 U 形井。这是因为你有一些闲置土地。这里有 5,000 英尺,这里有 5,000 英尺,你可能在中间有一口井。

      因此,您无需钻两个 5,000 英尺的水平井,只需钻一个 10,000 英尺的水平井,经济效益就好得多。

      您还可以从一个位置获得 10,000 英尺的水平距离,而在某些情况下可能需要两个位置。

      因此,如果我们不回去钻一些 U 型井,我会感到惊讶,因为我们来到这里,在油田的起源或开端钻了 5,000 英尺的水平井。我认为你会因此在全国各地看到这种情况。

      现在,一些井下压力将会影响到它。一些井下地质也将会影响到它。但只要我们能够做到,我认为我们会做这些事情。

      ND:太棒了。谢谢你,Tim。

      TB:是的,完全正确。谢谢。

      ND:感谢您的收看。更多可操作的能源情报请访问hartenergy.com

      Expand Foresees Drilling U-Turns in Appalachia

      As Expand Energy leans into its newly combined Chesapeake-Southwestern acreage, Tim Beard, the company’s vice president of drilling, would be “surprised” if Expand did not drill U-turn wells in the Appalachian Basin.

          Tim Beard

          Nissa Darbonne, executive editor-at-large, Hart Energy: Hi. Thank you for joining us. I'm Nissa Darbonne, executive editor-at-large for Hart Energy. I'm visiting with Tim Beard. Tim is vice president of drilling for Expand Energy, the newly merged Chesapeake and Southwestern. Tim, thank you for joining us.

          Tim Beard, vice president of drilling, Expand Energy: Thanks for having me.

          ND: Tim was among speakers this morning at DUG Appalachia in Pittsburgh. Tim, we talked about a lot of drilling and completions, obviously, on stage. Three areas in particular I wanted to zero in on would be—first, obviously, Expand has been DUC-ing and deferring TILs and curtailing some existing wells via choke. Whereabout is Expand now in that program?

          TB: Yeah. So great question. We have about 80 deferred TILs. So a deferred TIL has been drilled. It's been completed. We just haven't turned it in-line. So we have about 80 of those wells. So about a Bcf/d of production is what is sitting there behind the wellhead.

          Currently we have about 60 DUCs, plus or minus, and we have been curtailing. And that number fluctuates based on the price. I think we have a couple 100 [MMcf] currently curtailed around the country, so be it Appalachia, which is our Southwest Appalachia asset, our Northeast Appalachia asset or the Haynesville.

          Those three areas, we have some amount of gas—and/or liquids in the case of Southwest Appalachia—that we are curtailing currently.

          ND: You mentioned the Haynesville. You operate both in the Haynesville and in the Appalachian Basin. A fellow Haynesville operator in the original Haynesville has been doing an extreme stepout in terms of numbers of miles from the original Haynesville/Bossier program north of Houston and making some incredible wells. But these are also super deep, super high pressure, super high temperature. Have y'all been looking at that program to see if there's anything you can apply to yours?

          TB: Yeah, absolutely. So we've been looking over the fence and as I said in the other room, I think all operators are remiss if they're not learning from others, looking over the fence, seeing what they're doing, be it from a geologic perspective and/or from an operations perspective. And so we've been paying attention to what they're doing.

          I think not only are they seeing tremendous results from a production perspective, but they're starting to lower the price [of D&C]. If you look at the cost of those wells, it's a little bit cost prohibitive currently at plus or minus $3,000 per foot [for] 10,000-foot laterals,. We can all do that math pretty quickly. Those are expensive wells.

          But as we were talking earlier, they're just phenomenal from a production perspective. And so as commodity price improves, that area is probably going to continue to get more and more attention. And as midstream companies come in and are able to take that gas out of that area [that's] also a big deal for those folks that are working there.

          But how's it affecting us? Well, obviously we're paying attention from a geologic perspective. Do we need to move that direction? But secondarily, it is so extreme from a temperature and pressure perspective that these guys are having to learn how to drill, how to complete, how to produce these wells.

          And the good news is, across the industry, people are going to find a way. We've seen that over time.

          We talked a little bit this morning about really short laterals, right? When we got to a mile, we thought we were doing great. Now we're out to five miles drilling laterals.

          But as I think back to the Haynesville, their temperatures are in excess of 400 F. Pressure is incredibly high. And so the service companies have to come alongside—and they have—and develop tools that can handle these extreme conditions.

          And so when they develop those tools, we can then take them to the Louisiana side of the Haynesville where our conditions aren't quite as harsh—still very hot, still very high pressure, but relative to what they're doing in Texas, a little bit different.

          And it's going to make us better. And we've already seen some of that, where our efficiencies in the Haynesville are continuing to get better in some of the technology that we're using from a hot-hole perspective is coming from some of the stuff that they're doing in East Texas.

          ND: And also in terms of getting better, one of Expand’s two predecessors, Chesapeake, was an early… was second in making a U-turn well. That was actually in the Eagle Ford.... And there are three now in the original Haynesville where you operate, but is Expand interested in U-turns in Appalachia?

          TB: Yes. I'll be surprised if we don't do some U-turn wells over the next couple of years. And the "why" behind the U-turn wells, it's not just to be cute and drill a U-turn well. It's because you have some stranded acreage. You have 5,000-foot here, you have 5,000-foot here, you might have a well in the middle.

          And so instead of two 5,000-foot laterals, you drill one 10,000-foot lateral and the economics are just much, much better.

          You're also getting that 10,000 foot lateral from just one location versus potentially two in some instances.

          And so I will be surprised, because we came out here and we drilled 5,000-foot laterals at the genesis or the beginning of the play, if we don't go back and drill some U-turn wells. And I think you'll see that across the country because of that.

          Now there's some downhole stresses that are going to play into it. There's some downhole geology that's going to play into it. But where we can, I see that [is] something that we will do.

          ND: Super. Thank you Tim.

          TB: Yep, absolutely. Thank you.

          ND: And thank you for joining us. Find more actionable energy intelligence here at hartenergy.com.
