Comstock Resources Inc.鈥檚 first far stepout Haynesville wildcat鈥檚 results are a win, while its first Bossier well in the new play is indicating an EUR of 3.5 Bcf per 1,000 feet of lateral.
鈥淲e keep drilling these wells, so obviously we're not totally displeased with what we've seen,鈥� Jay Allison, Comstock chairman and CEO, told securities analysts and investors in an earnings call Aug. 2.
鈥淎nd we're going to continue to drill the wells.鈥�
The first Haynesville well, McCullough Ingram A #1, in the new play in Robertson and Leon counties was turned into sales this past June 20. It IP鈥檈d at 35 MMcf/d from 8,256 ft of completed lateral at a total vertical depth of 17,836 ft.
The reported IP is what the well has shown to date while it is still cleaning up, said Dan Harrison, Comstock COO.
Meanwhile on the EUR estimate, the first Bossier well, the Circle M #1H, came in with 37 MMcf/d from a 7,900-ft lateral in April of 2022. The estimate of 3.5 Bcf per 1,000 feet of lateral is based on a Netherland Sewell & Associates Inc. analysis.
Comstock also reported Aug. 2 that a fourth Bossier well, Dinkins JG #1, IP鈥檈d at 34 MMcf/ from 9,565 ft of completed lateral in Lower Bossier at a total vertical depth of 18,042 ft. The well was put into sales on May 24.
Two more wells are being completed currently and are expected to be online before October. Another well is being drilled.
Comstock dropped one of its two rigs drilling in the play to pick up a newer rig arriving later this month, Harrison said. The plan is to have three rigs in the play in 2024 to HBP its roughly 200,000 net acres.
Comstock is continuing to add to its block, Allison added, filling in blank spaces to be able to make more multi-section laterals. It is not expanding outside the boundary of the geologic map it developed for the sweet spot, though, he added.
鈥淲e鈥檝e leased approximately 90% of our targeted acres. So we're almost at the finish line.鈥� Getting there will likely be by year-end, he said, as this 鈥渓ow gas-price environment is contributing to our success by keeping [leasing] competitors away.鈥�
Comstock鈥檚 first two wildcats in the play鈥擟azey Black A #1H and Circle M Allocation #1H鈥攃ame in with 42 MMcfe/d and 37 MMcf/d, respectively, from Bossier. Lateral lengths were 7,900 ft for each.
A third well, Campbell #2H, came in with 36 MMcf/d from Bossier. Lateral length was 12,763 ft.
“据我们所知,实际上没有人能够像我们一样有效地钻探这些井的深度和横向长度,以及我们所遇到的高温,”艾利森说。
根据 20 年前在该地区钻探的 Bossier 井的测井数据,温度超过 400 F,压力超过 17,000 psi。
至于井底压力,哈里森说,“我们在如何降低油井压力方面非常保守”。显然,我们并不想仅仅在油井可以做的事情上获得超级一流的 IP 率。现在。”
不过,他说,在相同的阻流尺寸下,海恩斯维尔的压力更大。“与 Bossier 井相比,Haynesville 井的产能肯定要好得多。”
哈里森补充说,波西尔井是一种学校教育。“海恩斯维尔永远是我们的首要目标。当我们第一次开始这项工作时,我们知道由于深度和温度的原因,钻这些井会很困难。”
迄今为止,Comstock 已将钻探时间缩短了 20 天。
“显然,这些井并不容易钻探。我想每个人都意识到我们在这里接受了一个很好的挑战,”哈里森说。
垂直孔遇到循环漏失区。此外,钻头必须穿过特拉维斯峰的一段厚路,“这里非常坚硬、磨蚀性强,钻孔速度很慢。”
