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 »

Reducing Drilling Pollution—Wyoming Did It, No Big Deal. Will Texas?

ozonegraphThe technological advances that led to the “shale revolution” have undoubtedly had a large economic impact on the Texas economy – something state leaders and the oil and gas industry are never shy about pointing out. But the impact drilling has on air quality and public health, that’s something energy-friendly Texas has not been so quick to recognize.

When not managed responsibly, drilling operations can contribute to the formation of ozone, also commonly known as smog. At certain concentrations, this pollution can trigger asthma attacks and cause other severe respiratory illnesses.

San Antonio is one place that’s seeing the clear connection between drilling and lower air quality, thanks to increased drilling just south of the city from the Eagle Ford Shale region. Before 2008, ozone levels in San Antonio had been steadily dropping, but when the shale revolution hit and drilling increased, regional ozone readings started going up.  In fact, based on air quality monitor readings from the last three years, San Antonio’s air quality is the 2nd worst in the state.  This correlation between drilling and ozone levels has been documented by The University of Texas and the Alamo Area Council of Governments, both of which concluded oil and gas activity in the Eagle Ford Shale is materially impacting ozone levels in San Antonio.
