PECOS COUNTY, Texas – Sharon Wilson skilled her cumbersome, black digicam on a skinny, metal tower subsequent to a pure fuel compression station.
The display screen of her Optical Gasoline Imaging digicam lit up with heat colours, indicating that methane was pouring out of the tower.
Wilson, of the non-profit Oilfield Witness, was recording the Oklahoma-based firm ONEOK’s Coyanosa station in its WesTex pipeline community. The station maintains pipeline stress of pure fuel throughout transportation.
Wilson documented widespread flaring, venting and different methane releases throughout every week within the Texas Permian Basin this month. Pure fuel costs within the Permian Basin fell under zero throughout March. When pure fuel costs are low, firms usually tend to vent or flare methane. Pipeline capability to move the fuel out of the Permian Basin is at the moment restricted, which might additionally lead to extra flaring.

That’s unhealthy information for efforts to combat local weather change. Pure fuel is usually made up of methane and the Permian Basin is the single-largest supply of methane emissions within the U.S. oil and fuel business. As a greenhouse fuel, methane is about 80 instances stronger at warming the environment than carbon dioxide over a 20-year interval.
Flaring additionally releases a wide range of hazardous air pollution, together with risky natural compounds like benzene, a carcinogen, and contributes to ground-level ozone, a pollutant that causes respiratory sickness and coronary heart illness.
The Permian Basin produces extra crude oil than another in North America and is now the second-most productive fuel basin within the nation. Drilling for oil yields the largest income for vitality firms, however oil drilling additionally produces massive volumes of pure fuel. Corporations flare pure fuel in the event that they aren’t in a position to promote or transport it, a apply often known as routine flaring.
“They need to do away with the fuel as a result of it’s going to price them cash to get it in a pipeline,” Wilson stated.
On the Waha Hub, the place pure fuel produced within the Permian Basin is funneled into pipelines to achieve demand facilities, the worth for fuel dipped under zero on March 13 and was nonetheless unfavorable as of March 21. Analysts warn that the capability for pipelines to move fuel away from the Permian Basin is proscribed.
The ONEOK compression station the place Wilson documented methane emissions connects fuel producing wells within the Permian Basin to the Waha Hub.
An ONEOK spokesperson stated throughout the time interval Wilson documented emissions on the compression station, “no unpermitted emissions occurred.” Nonetheless, a spokesperson for the Texas Fee on Environmental High quality stated the emissions weren’t reported to their company, as required by legislation, and they might be trying into the incident.
Worth of Gasoline Key to Methane Query within the Permian Basin
The Permian Basin sprawls throughout the arid panorama of West Texas and southeastern New Mexico. The amount of this fuel within the Permian has practically tripled since 2018, in keeping with the Vitality Data Administration.
At drilling websites, the Railroad Fee of Texas enforces State Rule 32, which prohibits flaring pure fuel. Nonetheless, the Fee grants hundreds of exceptions a yr. Corporations can request an exemption to flare when there’s not sufficient pipeline capability. Throughout January 2024 in Texas, 2.65 % of the pure fuel produced at oil wells, often known as casinghead fuel, was flared, in keeping with info offered by the Railroad Fee. Newer knowledge was not accessible.
“Within the rush to develop the oil within the space, [companies] don’t plan for methods to handle the fuel that’s produced on the nicely,” defined Elizabeth Lieberknecht, a regulatory and legislative supervisor on the Environmental Protection Fund.
The Environmental Safety Company issued its remaining rule to scale back methane emissions underneath the Clear Air Act in December. The brand new guidelines, as written, will ultimately prohibit routine flaring, which is at the moment allowed in Texas. Nonetheless, the attorneys basic of Texas and one other two dozen states have challenged the federal rule. The authorized challenges could delay implementation.
Intensive pipeline development has facilitated transferring pure fuel out of the Permian. However East Daley Analytics, which offers vitality market evaluation, and Validere, an emissions knowledge firm, projected in a Might 2023 report that, beginning in 2024, manufacturing development within the Permian Basin as soon as once more may exceed fuel “takeaway” capability. The authors anticipated the issue to peak in mid-2024. When there’s not sufficient pipeline capability, firms can both restrict drilling or improve flaring.
The report’s authors wrote that some firms “will possible choose to flare” as a substitute of ready to drill wells whereas pipeline capability is proscribed. An East Daley consultant stated the corporate has not up to date its evaluation because the Might 2023 report and couldn’t remark additional.
Joshua Rhodes, a analysis scientist on the College of Texas, Austin, stated there’s a “good storm” making a glut of fuel within the Permian. He pointed to a gentle winter that drove down demand for fuel. In the meantime renewables within the area like photo voltaic and wind are producing nicely. A number of pipelines are at the moment present process upkeep within the area, additional constraining capability.
Whereas the US exported document volumes of liquified pure fuel throughout 2023, demand within the European market is flattening. Pure fuel consumption in Europe fell to a 10-year low in 2023.
“The issue is that oil demand continues to be excessive,” he stated. “That’s what’s persevering with the manufacturing of pure fuel.”
The Vitality Data Administration reported that the worth of pure fuel on the Waha Hub fell to -$0.25/MMBtu on March 13. The worth remained unfavorable the following week, dropping as little as -$1.16/MMBtu on March 18. In areas like Pennsylvania’s Marcellus Shale, which is dominated by pure fuel, drillers are dialing again. However within the Permian Basin, the place oil is essentially the most profitable commodity, drillers nonetheless added rigs, the massive drilling websites, throughout March. These drillers will proceed to supply pure fuel alongside the oil, regardless of the drop in costs and pipeline capability issues.
EDF’s Lieberknecht stated the impacts of worth fluctuations on flaring present that voluntary commitments from oil and fuel firms usually are not sufficient. She stated the federal methane rule will stage the enjoying discipline and, ultimately, part out routine flaring and require drillers to seize the fuel as a substitute.
“We predict that’s an enormous step ahead, particularly in Texas the place we don’t have any significant regulation requiring operators to try this,” she stated.
Grassroots Emissions Monitoring Continues
Wilson, together with her Optical Gasoline Imaging digicam, is accustomed to seeing rampant methane emissions whereas “floor truthing” within the Permian Basin. However she stated the unfavorable pure fuel worth gave the impression to be contributing to elevated emissions throughout her latest discipline work.
“It’s not simply flaring, we noticed quite a few blowdowns, we noticed actually intense tank emissions,” she stated. Blowdowns happen when gasses are launched at wells or pipelines to scale back stress and are even worse for the local weather than flaring. “There are emissions all over the place.”
Wilson stated measuring emissions on-site is vital to seize methane releases that firms don’t report back to regulators. Her earlier work has documented that almost all of flares go unreported.
“We noticed simply an unbelievable quantity of emissions that will not have been detected if we weren’t on the market,” she stated.
In Texas, the Railroad Fee and the TCEQ break up jurisdiction over emissions from oil and fuel drilling, processing and refining.
Railroad Fee spokesperson Patty Ramon stated purposes to flare endure a “thorough” evaluate. Nonetheless, data within the state flaring question database point out that the Railroad Fee has authorized 1,077 purposes to flare since Jan. 1, 2024, and denied one software.
The elected leaders of the Railroad Fee have been essential of the federal methane rule. Commissioner Wayne Christian has referred to as the rules “extra bureaucratic purple tape stifling enterprise.”

The TCEQ regulates air emissions from different phases of the oil and fuel provide chain, together with processing vegetation and refineries. A TCEQ spokesperson stated that firms should report any emissions occasions inside 24 hours.
The Division of Vitality has additionally awarded $134 million to the Texas Fee on Environmental High quality for plugging low-producing wells to scale back methane emissions. The spokesperson stated the company is working with the Division of Vitality to finalize this system for the funding.
In New Mexico, the New Mexico Vitality, Minerals and Pure Assets Division’s Oil Conservation Division enforces the state’s methane flaring rules. Spokesperson Sidney Hill stated the company is “usually conscious” of the potential influence of pure fuel costs on operations. The state’s guidelines prohibit flaring when there’s restricted pipeline capability.
“Simply because costs are low doesn’t imply routine flaring can be permitted,” he stated.
