Matador 的 U 型侧向特拉华州测试比 2 英里直孔效果更好

根据州数据,Matador Resources 在德克萨斯州洛文县进行的八次测试结果包括两条 2 英里长的掉头横管、五条 2 英里长的直横管和一条 1 英里长的直横管。

根据德克萨斯州的数据, Matador Resources在特拉华盆地进行的两次 2 英里调头水平井测试,在投产后的前 11 个月内,其表现优于相邻的 2 英里直水平井。

到目前为止,这两个 U 型侧向井已在位于德克萨斯州洛文县门托内以北约四英里处的 11 口井开发项目中使用。

截至 8 月份,U 形 JJ Wheat NW WF #2021H 的平均产量为每侧英尺 0.048 桶/天,高于四个相邻直侧枝 8 月份平均每英尺 0.038 桶/天至每英尺 0.043 桶/天的产量。

根据德克萨斯州铁路委员会 (RRC) 的数据,它被降落在沃尔夫坎普 XY,而四根棍子则位于沃尔夫坎普 A 和 B。

包括#2021H 在内,五个水平段的长度范围从 10,036 英尺到 10,752 英尺。

隔壁,Matador 通过三项测试改变了这个项目。

根据 RRC 的数据,2 英里长的 U 型转弯井 JJ Wheat SE WF #2024H 在 Wolfcamp XY 的钻孔总深度为 8,659 英尺,投产后前 11 个月平均每侧英尺产量为 0.075 桶/天。

相邻的 1 英里长油田 JJ Wheat WF SESE #214H 截至 8 月平均每英尺 0.076 桶/天。它也位于 Wolfcamp XY。油田水平段长度为 4,876 英尺。

从同一平台的另一角度看,Matador 在 Wolfcamp A 钻出了 2 英里长的直水平井,编号为 Barnett Trust WFA NWSE #223H。根据 RRC 的数据,截至 8 月份,这个 10,036 英尺深的井的平均产量为每水平英尺 0.043 桶/天。

掉头省钱

根据 U 型水平井追踪器 Udriller.com 的数据,自 2023 年 10 月将油井投入销售以来,Matador 已在新墨西哥州建造了五个 U 型水平井,即位于下阿瓦隆埃迪县的 Janie Conner #120H 井和位于利县 Bone Spring 的四个 Burke State 井。

目前尚未获得这些水平井的数据。

Matador 公司董事长兼首席执行官乔·福兰 (Joe Foran) 在 10 月 23 日的收益电话会议上告诉投资者,五口新的 U 型分支井的钻探速度比前两口快 30%。

此外,该公司还在伯克州的四口井上采用了远程模拟压裂完井技术。

四口 2 英里长的 U 型横向 Burke State 井位于 1 英里长的区块内,Matador 需要凿八个横向井才能开采同等长度的岩石。

福兰说:“与钻探八个一英里长的井相比,该团队估计每个 U 形转弯井可节省 300 万美元的成本,因为通过取消八个一英里长的井中的四个的垂直部分。”

Matador 在特拉华盆地拥有 196,200 英亩净油田,在 20 多个油区内分布着 11 个油层,共有 1,100 口油井在产。该公司预计到年底将有 110 口油井实现销售。

调头 IP

根据 RRC 的数据,最初的 JJ Wheat U-turn 测试的前 24 小时 IPs 也高于其直线横向 Wolfcamp 测试的 IPs,分别为 1,266 桶和 1,153 桶。

其中一条 2 英里长的直水平井储量为 1,098 桶;另外四条水平井的储量不足 800 桶。

Matador 油藏工程执行副总裁 Tom Elsener 在 2 月中旬的投资者电话会议上表示,“尽管它们是 U 型转弯井,但它们的表现就像一条 2 英里长的笔直水平井一样——压力非常高,IP 速率在 2,100 到 2,400 桶油当量/天之间 [包括天然气]。”

当时,U 型 JJ Wheat 井已投产 4 个多月。除了石油,在投产后的前 11 个月内,每口井还产出 10 亿立方英尺至 13 亿立方英尺的套管头天然气。

埃尔森纳说:“从生产结果来看,你不会知道它是一次 U 型转弯还是 2 英里横向偏移有什么区别。”

今年 2 月,Matador 预计未来两年内将建造多达 20 口 U 型井。

“我已经准备好再做一些这样的事情了。”但是,一开始,“我们仍然处于学习阶段,”埃尔森纳说。

“我们将了解不同地区的一些不同目标。”我仍然认为我们处于行走模式。我们还没有完全进入奔跑模式。

“但我认为我们对此非常乐观。”

74 处掉头井

根据 Udriller.com 的连续统计,自 2019 年壳牌石油在洛文县进行试点以来,迄今为止,运营商已在美国本土 48 个州内钻探了 74 口 U 型转弯井。

除四个盆地外,其余均为油田:二叠纪盆地、鹰福特页岩盆地、丹佛-朱尔斯堡盆地(DJ 盆地)、巴肯盆地和阿纳达科盆地。

在天然气领域,Ascent Resources于 2023 年 4 月在俄亥俄州东部尤蒂卡的天然气加权航道上获得了一口气,即 Echo S ATH HR #3H。根据俄亥俄州自然资源部的数据,截至今年 6 月,该气田已生产了 59 亿立方英尺天然气和 10,739 桶石油。

据 Udriller.com 报道, Coterra Energy将于 2023 年 9 月在宾夕法尼亚州萨斯奎哈纳县马塞勒斯开钻一口井。

在海恩斯维尔页岩区,GeoSouthern Energy的 GEP Haynesville 于一月份在路易斯安那州德索托县开钻。

这一结果促使康斯托克资源公司于 7 月在附近设立了一个油田。该公司计划在一个区块的租赁期内进行两次 U 型调整。

康斯托克首席运营官丹·哈里森 (Dan Harrison) 在 8 月份的电话会议上告诉投资者,在孤立区域铺设四根一英里长的电线杆将需要两个底座,耗资 4,000 万美元。

如果改建两口掉头井,则只会产生一个平台,成本为 3200 万美元。

如果成功的话,“我们库存中的大部分短井都将转换为长水平井,”他说。

他补充道,开采这些油井是必要的。“除非你‘有’必要这样做,否则你会考虑改善库存,但很多人可能不会去那里。”

不过,钻马蹄形井还是有一定的风险。扭矩和阻力更大。这显然意味着,当你在 180 度弯头周围推拉管道时,它会增加更多的阻力,导致钻头进出孔洞。

“当你观察进出洞的阻力时,10,000 英尺的马蹄铁可能更像是 15,000 英尺的直线水平线。”

Matador’s U-lateral Delaware Tests Outproduce 2-mile Straight Holes

Matador Resources' results from eight Loving County, Texas, tests include two 2-mile U-turn laterals, five 2-mile straight laterals and one 1-mile straight lateral, according to state data.

Matador Resources’ first two 2-mile U-turn-lateral tests in the Delaware Basin are outperforming adjacent 2-mile straight laterals in their first 11 months online, according to Texas state data.

Both U-laterals are in a development of 11 wells to date, about four miles north of Mentone, Texas, in Loving County.

The U-shaped JJ Wheat NW WF #2021H produced an average of 0.048 bbl/d per lateral foot through August, higher than the 0.038 bbl/d per foot to 0.043 bbl/d per foot averaged through August from four adjacent straight-lateral sticks.

It was landed in Wolfcamp XY, while the four sticks are in Wolfcamp A and B, according to Texas Railroad Commission (RRC) data.

Including the #2021H, the five laterals range from 10,036 ft to 10,752 ft.

Next door, Matador varied the project in three tests.

A 2-mile U-turn, JJ Wheat SE WF #2024H, averaged 0.075 bbl/d per lateral foot in its first 11 months online from a total 8,659 ft of hole in Wolfcamp XY, according to the RRC.

An adjacent 1-mile stick, JJ Wheat WF SESE #214H, averaged 0.076 bbl/d per lateral foot through August. It is also landed in Wolfcamp XY. The lateral is 4,876 ft.

In another look from the same pad, Matador made a 2-mile straight lateral, Barnett Trust WFA NWSE #223H, in Wolfcamp A. Production through August from the 10,036-ft hole averaged 0.043 bbl/d per lateral foot, according to RRC data.

U-turns save money

Since turning the wells to sales in October 2023, Matador has made five more U laterals in New Mexico—the Janie Conner #120H in Eddy County, in the Lower Avalon and four Burke State wells, all in Bone Spring, in Lea County—according to U-lateral tracker Udriller.com.

Data was not yet available on those laterals.

Joe Foran, Matador chairman and CEO, told investors on an Oct. 23 earnings call that the five new U-laterals were drilled 30% faster than the first two.

Also, it used remote, simul-frac completions on the four Burke State wells.

The four 2-mile U-lateral Burke State wells are in a 1-mile section where Matador would have needed to make eight laterals to tap the equivalent length of rock.

“The team estimated $3 million in cost savings per U-turn well when compared to the alternative of drilling eight one-mile … wells,” Foran said, by eliminating the vertical sections of four of the eight one-mile holes.

Matador has 196,200 net acres in the Delaware Basin with 1,100 wells producing from 11 intervals in more than 20 zones. It expects to turn to sales 110 net wells by year-end.

U-turn IPs

The initial JJ Wheat U-turn tests’ first-24-hour IPs were also higher than their straight-lateral Wolfcamp counterparts, coming in with 1,266 bbl and 1,153 bbl, according to RRC data.

One of the 2-mile straight laterals IP’ed 1,098 bbl; the other four, fewer than 800 bbl.

“Even though they're U-turn wells, they performed just like a straight 2-mile-long lateral—very high pressures and IP rates of between 2,100 and 2,400 boe/d [including gas],” Tom Elsener, Matador executive vice president of reservoir engineering, said in a mid-February investor call.

At the time, the U-shaped JJ Wheat wells were online more than four months. In addition to oil, they made between 1 Bcf and 1.3 Bcf of casinghead gas each in their first 11 months.

“You wouldn't know the difference if it was a U-turn or 2-mile lateral from the production results,” Elsener said.

In February, Matador estimated making up to 20 U-turn wells in the next two years.

“We’re ready to do a few more of those.” But, at first, “we still are kind of in the learning phase,” Elsener said.

“We're going to learn about some different targets in different areas. … I still think we're kind of in the walking mode. We're not quite in the running mode yet.

“But I think we're very optimistic about it.”

74 U-turn wells

To date, operators have spud 74 U-turn wells across the Lower 48 since a 2019 Shell Oil pilot in Loving County, according to a running tally at Udriller.com.

All but four have been in oil plays: the Permian, Eagle Ford Shale, Denver-Julesburg Basin (D-J Basin), Bakken and Anadarko Basin.

In gas plays, Ascent Resources landed one, Echo S ATH HR #3H, in the Utica’s gas-weighted fairway in eastern Ohio in April 2023. Through this past June, it has produced 5.9 Bcf and 10,739 bbl of oil, according to Ohio Department of Natural Resources data.

Coterra Energy spud one in the Marcellus in Susquehanna County, Pennsylvania, in September 2023, according to Udriller.com.

In the Haynesville Shale, GeoSouthern Energy’s GEP Haynesville spud one in DeSoto Parish, Louisiana, in January.

The results prompted Comstock Resources to put one nearby in July. It plans two U-turns in a one-section lease.

Four one-mile sticks in the isolated section would have involved two pads and cost $40 million, Dan Harrison, Comstock COO, told investors in an August call.

Making two U-turn wells instead will result in a single pad at a cost of $32 million.

If successful, “the majority of all the short wells in our inventory will convert to long laterals,” he said.

Making these wells is a matter of necessity, he added. “Until you kind of ‘have’ to do it—you're looking at your inventory improvement—a lot of people probably just don't push to go there.”

There is some risk in drilling a horseshoe well, though. There is more torque and drag. “I mean, obviously, when you're pushing and pulling pipe around the 180-degree bend, it adds more drag, tripping in and out of the hole.

“So a 10,000-foot horseshoe [is] maybe more like the equivalent of a 15,000-foot straight lateral when you look at the drag going in and out of the hole.”
