PECOS COUNTY, Texas – Sharon Wilson educated her cumbersome, black digicam on a skinny, metal tower subsequent to a pure gasoline 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 strain of pure gasoline throughout transportation.
Wilson documented widespread flaring, venting and different methane releases throughout per week within the Texas Permian Basin this month. Pure gasoline costs within the Permian Basin fell under zero throughout March. When pure gasoline costs are low, corporations usually tend to vent or flare methane. Pipeline capability to move the gasoline out of the Permian Basin is at the moment restricted, which might additionally end in extra flaring.

That’s dangerous information for efforts to battle local weather change. Pure gasoline is usually made up of methane and the Permian Basin is the single-largest supply of methane emissions within the U.S. oil and gasoline trade. As a greenhouse gasoline, methane is about 80 instances stronger at warming the ambiance 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 every other in North America and is now the second-most productive gasoline basin within the nation. Drilling for oil yields the largest earnings for vitality corporations, however oil drilling additionally produces giant volumes of pure gasoline. Corporations flare pure gasoline in the event that they aren’t in a position to promote or transport it, a apply referred to as routine flaring.
“They must eliminate the gasoline 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 gasoline produced within the Permian Basin is funneled into pipelines to achieve demand facilities, the worth for gasoline dipped under zero on March 13 and was nonetheless damaging as of March 21. Analysts warn that the capability for pipelines to move gasoline away from the Permian Basin is restricted.
The ONEOK compression station the place Wilson documented methane emissions connects gasoline producing wells within the Permian Basin to the Waha Hub.
An ONEOK spokesperson stated through 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’d be trying into the incident.
Value 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 gasoline within the Permian has almost tripled since 2018, in line with the Power Info Administration.
At drilling websites, the Railroad Fee of Texas enforces State Rule 32, which prohibits flaring pure gasoline. Nonetheless, the Fee grants 1000’s of exceptions a 12 months. Corporations can request an exemption to flare when there’s not sufficient pipeline capability. Throughout January 2024 in Texas, 2.65 % of the pure gasoline produced at oil wells, referred to as casinghead gasoline, was flared, in line with data offered by the Railroad Fee. More moderen knowledge was not obtainable.
“Within the rush to develop the oil within the space, [companies] don’t plan for learn how to handle the gasoline 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 cut back methane emissions beneath the Clear Air Act in December. The brand new guidelines, as written, will finally prohibit routine flaring, which is at the moment allowed in Texas. Nonetheless, the attorneys common of Texas and one other two dozen states have challenged the federal rule. The authorized challenges might delay implementation.
Intensive pipeline development has facilitated shifting pure gasoline out of the Permian. However East Daley Analytics, which gives 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 might exceed gasoline “takeaway” capability. The authors anticipated the issue to peak in mid-2024. When there’s not sufficient pipeline capability, corporations can both restrict drilling or enhance flaring.
The report’s authors wrote that some corporations “will doubtless decide to flare” as an alternative of ready to drill wells whereas pipeline capability is restricted. An East Daley consultant stated the corporate has not up to date its evaluation for the reason that Might 2023 report and couldn’t remark additional.
Joshua Rhodes, a analysis scientist on the College of Texas, Austin, stated there’s a “excellent storm” making a glut of gasoline within the Permian. He pointed to a light winter that drove down demand for gasoline. 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 america exported report volumes of liquified pure gasoline throughout 2023, demand within the European market is flattening. Pure gasoline consumption in Europe fell to a 10-year low in 2023.
“The issue is that oil demand remains to be excessive,” he stated. “That’s what’s persevering with the manufacturing of pure gasoline.”
The Power Info Administration reported that the worth of pure gasoline on the Waha Hub fell to -$0.25/MMBtu on March 13. The worth remained damaging 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 gasoline, drillers are dialing again. However within the Permian Basin, the place oil is probably the most profitable commodity, drillers nonetheless added rigs, the massive drilling websites, throughout March. These drillers will proceed to provide pure gasoline alongside the oil, regardless of the drop in costs and pipeline capability issues.
EDF’s Lieberknecht stated the impacts of value fluctuations on flaring present that voluntary commitments from oil and gasoline corporations should not sufficient. She stated the federal methane rule will stage the taking part in discipline and, finally, section out routine flaring and require drillers to seize the gasoline as an alternative.
“We predict that’s an enormous step ahead, particularly in Texas the place we don’t have any significant regulation requiring operators to do this,” she stated.
Grassroots Emissions Monitoring Continues
Wilson, along with her Optical Gasoline Imaging digicam, is accustomed to seeing rampant methane emissions whereas “floor truthing” within the Permian Basin. However she stated the damaging pure gasoline value gave the impression to be contributing to elevated emissions throughout her current 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 cut back strain 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 corporations 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 may not have been detected if we weren’t on the market,” she stated.
In Texas, the Railroad Fee and the TCEQ cut up jurisdiction over emissions from oil and gasoline drilling, processing and refining.
Railroad Fee spokesperson Patty Ramon stated functions to flare endure a “thorough” evaluate. Nonetheless, information within the state flaring question database point out that the Railroad Fee has authorized 1,077 functions to flare since Jan. 1, 2024, and denied one software.
The elected leaders of the Railroad Fee have been vital of the federal methane rule. Commissioner Wayne Christian has referred to as the rules “extra bureaucratic crimson tape stifling enterprise.”

The TCEQ regulates air emissions from different phases of the oil and gasoline provide chain, together with processing crops and refineries. A TCEQ spokesperson stated that corporations should report any emissions occasions inside 24 hours.
The Division of Power has additionally awarded $134 million to the Texas Fee on Environmental High quality for plugging low-producing wells to cut back methane emissions. The spokesperson stated the company is working with the Division of Power to finalize this system for the funding.
In New Mexico, the New Mexico Power, Minerals and Pure Sources Division’s Oil Conservation Division enforces the state’s methane flaring rules. Spokesperson Sidney Hill stated the company is “typically conscious” of the potential impression of pure gasoline 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 will probably be permitted,” he stated.
