Researchers at the Nicholas School of the Environment at Duke University have written an article published in the Proceedings of the National Academy of Sciences titled “Methane contamination of drinking water accompanying gas-well drilling and hydraulic fracturing,” which finds “systematic evidence for methane contamination of drinking water associated with shale-gas extraction” in the Marcellus Shale in Pennsylvania and New York. The article has already elicited a strong response from the industry. To my knowledge, this is the first scientifically based study finding a correllation between the drilling of shale wells and the contamination of aquifers.

The April issue of Discover, published by Kalmbach Publishing Co., contains an article on the potential environmental effects of hydraulic fracturing in gas shales, “Fracking Nation,” by Linda Marsa. Much of the article simply repeats allegations being made by environmental groups and landowners of alleged groundwater contamination by shale wells. But the article mentions four newer topics and recent allegations being made by opponents of shale gas development:

The EPA has issued its draft plan to study the impacts of hydraulic fracturing on drinking water in the U.S. Two state regulatory authorities have absolved frac’ed wells from responsibility for contaminating drinking water in Colorado and Texas. Maryland’s top einvornmental regulator urged lawmakers to impose a two-year moratorium on frac’ing, as Maryland’s legislature considers additional laws to regulate the practice. Meanwhile, the boom in shale gas drilling continues.

Josh Fox’s movie Gasland has been nominated for an academy award for best documentary. Gasland, widely criticized by the oil and gas industry, alleges that hydraulic fracturing is the cause of contamination of underground water resources across the country. (See my previous post about controversy surrounding the movie here.) The nomination, and the Fox’s movie about the alleged dangers of frac’ing, have made him into a celebrity.

In response to the Oscar nomination, Energy in Depth, a website sponsored by oil and gas associations including the Independent Petroleum Association, Texas Independent Producers and Royalty Owners’ Association, the Independent Oil & Gas Association, and Colorado OIl and Gas Association, has published a letter (Energy In Depth letter.pdf) addressed to the Academy of Motion Picture Arts and Sciences. In the letter, Energy in Depth calls the film an “expression of stylized fiction” not meeting the Academy’s criteria for a documentary. The letter says that the movie misstates the law and the rules, mischaracterizes the frac’ing process, and “flat-out makes stuff up.”

Josh Fox does not take this lying down. He has published a detailed rebuttal of Energy in Depth’s letter.  Josh has own his own website, www.gaslandthemovie.com, and his own facebook page about the movie and the frac’ing debate, and he was even awarded the Yoko Ono “Grant for Peace.” Clearly, he is enjoying his celebrity. Josh’s rebuttal is no small refutation. It runs to 38 pages and contains responses from his “amazing team of experts,” including Ron Bishop, PhD, lecturer in chemistry and biochemistry at SUNY Oneonta, Anthony Ingraffea, PhD, the D.C. Baum professor of engineering at Cornell,and Weston Wilson, a retired EPA engineer.  Energy in Depth’s letter to the Academy is not likely to lessen Josh’s time in the limelight and may actually increase his chances of grabbing that Oscar.

EPA’s order against Range Resources for allegedly charging groundwater with gas from its Barnett Shale wells has caused quite a stir.

The Texas Railroad Commission has issued two news releases, one on December 7 and one on December 8.  Commission Chairman Victor Carrillo said that he has told EPA Regions 6 Administrator Al Armendariz that “EPA’s actions are premature as the Railroad Commission continues to actively investigate this issue and has not yet determined the cause of the gas. This EPA action is unprecedented in Texas, and commissioners will consider all options as we move forward.” Commissioner Michael Williams said “this is Washington politics of the worst kind.  The EPA’s act is nothing more than grandstanding in an effort to interject the federal government into Texas business.” The December 8 press release said that the Commission has called a hearing for January 10 and “expects both parties, the EPA as well as Range Resources representatives, to appear before Hearings Examiners and testify as to the allegations made yesterday.” Range has said it will attend the hearing, but it understands that the EPA will not.

Arthur Berman, a geological consultant, has once again blasted the economics of gas shale plays — this time the Marcellus.  At the annual conference sponsored by the Association for the Study of Peak Oil & Gas – USA, held on October 7-9 in Washington, D.C., Mr. Berman made a presentation: “Shale Gas–Abundance or Mirage? Why the Marcellus Shale Will Disappoint Expectations.”  His power-point from that presentation may be found here:  Arthur Berman on Marcellus.pdf  Mr. Berman argues that only a small percentage of the areas now being touted as productive in shale plays — the “core areas” are economic at any price; that even within the core areas, performance is not uniform and the geology is complex; that the wells are very expensive and the break-even gas price is as high as $8-$12/mcf; that reserves have been overstated by the companies in the plays; that the industry is not properly estimating estimated ultimate recoveries from the wells; that changes in reporting rules recently adopted by the Securities and Exchange Commission allow companies to “book” estimated reserves prematurely; and that the economies of the plays will ultimately be reflected in lower share prices of the companies participating in the plays. 

For the Marcellus in particular, Mr. Berman asserts that infrastructure limitations — lack of pipeline and gas processing capacity — will slow development, that environmental issues — fears about groundwater contamination, proximity to urban areas, and regulatory restraints — will not go away, and that economics for drilling in the Marcellus Shale are no better than in the Barnett Shale. Mr. Berman says that shale gas is the nation’s next speculative bubble likely to burst.

Mr. Berman created a stir just a year ago when he published a similar gloomy analysis of the Barnett Shale, at the ASPO conference in October 2009.  At that time he was a contributor to a trade publication called World Oil, which is sent free to top oil & gas E&P executives. In early November 2009, World Oil was about to publish another article by Mr. Berman critical of shale plays, but the president of the publication ordered that it not be published. Mr. Berman resigned, and his editor Perry Fischer, who insisted that the article be published, was fired. All of this created a stir in the blogosphere. Fischer contended that World Oil executives were pressured by CEOs of two public E&P companies not to publish any more of Mr. Berman’s critiques. Tudor Holt & Pickering, who analyze the oil and gas industry, published a critique of Mr. Berman’s analysis, and two oil executives from Devon and Chesapeake wrote newspaper op ed pieces critical of his work. Chesapeake CEO Aubrey McClendon said at the time that he expected gas prices to continue to rise, which would lead to an increase in drilling and production in the shale plays. “We think all of the elements are in place for gas prices to be higher in 2010 than they are today,” McClendon said.

Recent happenings in Pennsylvania:

  • The controversy over natural gas in underground aquifers in Dimock Township, Pennsylvania continues. It was reported that private lab tests of contaminated water found chemicals used in hydraulic fracturing. Dimock resident Victoria Switzer said that the tests had found ethylene glycol, propylene glycol and toluene in her well water. The testing company said that the tests also found ethylbenzene and zylene in most of the affected water wells in the township. Read the Scranton Times-Tribune article here. The Pennsylvanie Department of Environmental Protection has fined Cabot Oil & Gas for improper casing and cementing that allegedly have caused natural gas to appear in Dimock’s ground water.
  • Cabot has denied that the tests show contamination of ground water by frac water from its wells. Cabot claims that it has not used xylene, ethyl benzene or toluene in its frac water. It said that the chemicals found in the ground water were present before Cabot ever drilled its wells, and Cabot notes that an automobile and truck repair garage is sited near the water wells tested and that these chemcials are primary constituents of car and truck fuel and are commonly found in gasoline spills.  See article here.

A study group at the Massachusetts Institute of Technology has concluded that natural gas will play a leading role in the U.S. over the next several decades, both in providing fuel for the nation’s energy needs and in reducing greenhous gas emissions. The study was conducted over two years by a group of thirty MIT faculty members, researchers and graduate students, assisted by an advisory committee of industry leaders and consultants. The study group has released an interim 80-page report summarizing its findings. A full report with additional analysis will follow later this year.

Among the study’s findings:

RigData has compiled the numbers of active drilling rigs by county for each of the major shale plays in Texas: Barnett, Haynesville and Eagle Ford. These serve as a good measure of the degree of activity in each of the counties within these plays.

The Barnett Shale rig count 

shows a total of 81 rigs in July. The rig count has held steady around 80 for the last several months. Activity is concentrated in the core area, Tarrant and Johnson Counties.
