Texans for Natural Gas uses misleading data on methane in Texas

Recently, Texans for Natural Gas (TXNG) issued a report claiming methane emissions have drastically decreased in several of the largest natural gas producing counties in Texas from 2011 to 2016.

The notion of methane emissions rapidly declining across Texas during the largest U.S. oil and gas boom of the century is described in the report’s blog post as amazing, which in fact it would be if the report were accurate. It isn’t. The TXNG report doesn’t even come close to providing a complete representation of methane emissions across the featured Texas counties. TXNG claims methane emissions declined 51 percent in several of the state’s largest producing natural gas counties, and 39 percent across ten of the largest oil-producing counties.

And here’s what data is missing: methane emissions generated from onshore production and gathering. Simply put, the vast majority of emissions aren’t even included. (What’s even worse, their original report failed to disclose that the emission data referenced in TXNG’s blog post only accounted for methane emissions from large midstream  gas facilities.) The revised report’s claims about 2016 reductions in Midland County only account for emissions from six processing plants and compressor stations while ignoring the over 2,000 oil and gas wells. Drawing broad conclusions from a tiny fraction of facilities is shoddy analysis at best and deliberately misleading at worst.

New Texas Permian oil and gas flaring report reveals excessive gas waste and major gaps in operator flaring practices

As companies flock to West Texas’ Permian Basin to cheaply drill for and extract oil and gas, some operators are flooding the night sky with natural gas flares, polluting the air with unhealthy and climate-altering pollutants, and wasting copious amounts of this important, domestic energy resource.

The Permian Basin, which stretches across 75,000 square miles in West Texas and southeastern New Mexico, is in the midst of one of the largest energy booms of the century. An estimated 60-70 billion barrels of recoverable oil is located in the area, which is worth roughly $3.3 trillion at current prices, according to IHS Markit. Oil isn’t the only resource in abundant supply. EIA estimates that operators in the Permian are producing 7.3 billion cubic feet of natural gas per day. But a rush to produce higher value oil has some Permian drillers simply flaring the gas instead of investing in gathering and pipeline infrastructure.

A new EDF flaring report, released this week, has uncovered a wide discrepancy between flaring rates among the top 15 oil and gas producers working in the Texas Permian Basin. Some of the oil and gas producers studied in the report are wasting close to 10 percent of their produced gas due to flaring practices, highlighting the fact that the oil and gas industry continues to struggle to control natural gas waste.

Oil & Gas Industry Mangles More Facts, Turns EDF Study Results Upside Down

Here we go again.

A new set of peer-reviewed scientific papers pointing to 50 percent higher than estimated regional methane emissions from oil and gas operations in Texas were published this week. And like clockwork, the oil and gas industry’s public relations machine, Energy In Depth, proclaimed that rising emissions are actually falling, and that the industry’s meager voluntary efforts are responsible.

This is, of course, wrong on both counts. In fact, it’s a willful misrepresentation of the findings.

First, the assertion that emissions are going down is flat wrong. EPA’s latest inventory released in April reports that in 2013 the oil and gas industry released more than 7.3 million metric tons of methane into the atmosphere from their operations—a three percent increase over 2012—making it the largest industrial source of methane pollution. So much for those voluntary efforts. Read More »

A Neighborly Approach to Cleaning the Air in South Texas

Is that flare operating efficiently? Is it dangerous to my health? Whom do I ask? Whom do I tell? These are the types of questions an emerging workshop developed by EDF and RGISC aims to answer.

The U.S. Energy Information Administration recently ranked the Eagle Ford Shale play as the nation’s largest oil field. But with oil wells often comes wasted gas, something Texas knows all too well. A huge portion of the gas pulled from oil wells in the Eagle Ford is burned away— often sending damaging pollutants into our environment.

An investigative report published in the San Antonio Express-News last year found “the rate of Eagle Ford flaring was 10 times higher than the combined rate of the state's other oil fields.” The same researchers found that from 2009 through the first seven months of 2014 oil and gas operators in the Eagle Ford region wasted about 94 billion cubic feet of natural gas – roughly enough gas to serve the heating and cooking needs of all the homes in San Antonio over four years. Excessive or improper flaring is not only a waste of a valuable resource, but can also have harmful health effects and damage the environment.  Read More »

Money to Burn? EDF Questions Public Health Priorities at TCEQ

Flaring in Eagle Ford Shale

The Texas Tribune recently published a piece debunking some of the science behind the Texas Commission on Environmental Quality’s (TCEQ) position on the national health standard for ozone – one of the most ubiquitous and harmful air pollutants on the planet. As outlined in the agency’s latest newsletter, TCEQ’s Director of Toxicology, Mike Honeycutt, questions the benefits of a stronger standard, even though public health experts across the country have been calling for a more protective standard for years. What’s more disappointing than the agency’s apparent anti-health position, however, is the lack of attention to other legitimate air pollution issues in Texas.

It would seem that the agency must have a surplus of staff, as well as unlimited resources to establish such an aggressive position on a standard that hasn’t been proposed yet. The reality is that there are so many more important things that the agency could and should be doing to serve and protect Texas citizens from real air pollution threats, including:  Read More »

TCEQ Study Suggests that Flare Emissions Could be Larger Than Reported

EDITOR'S NOTE: The final draft report was released May 24. Download the PDF here.

A soon-to-be released key flare emissions report could help answer the question of why Texas air toxics concentrations are higher than those reported through industrial emission inventories.

Footage of flare emissions captured by advanced monitoring technology at facility in Texas. The video was presented by TCEQ at the Hot Air Topics Conference on Jan 13, 2011 in Houston, TX. Flare is described as being oversteamed, resulting in reduced destruction efficiency and increased emissions.


Across the state, there are 1,500 flares registered with the Texas Commission on Environmental Quality. The “flaring” or burning of excess gases using these flares has been accepted industrial practice for combusting routine waste gases as well as for combusting large volumes of gases that may result from plant emergencies, such as those that could lead to a facility explosion. Air quality experts have long held that an increase in flare pollution has been a significant contributing factor in escalating smog levels and toxic “hot spots,” particularly in fenceline communities.
