Bryan Shaw, Chariman of the Texas Commission on Environmental Quality, published a letter in the Fort Worth Star Telegram assuring Fort Worth that there was no immediate health risk from contamination of air caused by oil and gas activities in the region. Shaw assured residents that “the TCEQ can state, without hesitation, that benzene levels in Fort Worth pose no immediate health risk.”

The TCEQ has taken extraordinary measures over the past several months to test air quality in and around Fort Worth after Al Amendariz, then an engineering professor at Southern Methodist University and now regional administrator for the Environmental Protection Agency, published a report that air emissions from oil and gas activity in the Barnett Shale play were significantly contributing to reduced air quality in the DFW area. The concerns were exacerbated by reports from the town of DISH, in Denton County, that air emissions from oil and gas facilities were causing health problems in that community.

The TCEQ has also come under more general criticism and scrutiny by the EPA since Armendariz’s appointment. The EPA has contended that the TCEQ’s air-permitting program violates federal law, and the EPA has threatened to take over the program from the TCEQ. The Texas Attorney General has filed a legal challenge to the EPA’s efforts to pre-empt the State’s permitting program. The TCEQ and the EPA are in discussions to try to resolve the dispute.

EOG Resources has filed an application with the Texas Railroad Commission proposing the adoption of temporary field rules for wells drilled in the Eagle Ford Shale in South Texas that could have a significant impact on thousands of oil and gas leases in the field. The application proposes to consolidate 27 designated fields that produce from the Eagle Ford Shale formation, and the proposed rules will replace any field rules previously adopted for those fields. The consolidated rules would apply to Eagle Ford Shale wells drilled in Railroad Commission of Texas Districts 1, 2 and 4. A copy of the notice of the Railroad Commission hearing for the adoption of the proposed rules may be found here: 
eagle ford field rules.pdf. The hearing is scheduled for June 25, 2010, at 9 am in the William B. Travis Sate Office Building, 1701 Congress Avenue, Austin. Persons wishing to participate in the hearing must file a notice of intent to appear at least five working days in advance of the hearing date and serve a copy of the notice on the applicant and any other parties of record. More information can be obtained by calling the Office of General Counsel of the Railroad Commission at 512-463-6848.

Field rules are adopted by the Railroad Commission to govern the spacing of wells in a field. They specify how far wells must be from each other, how far wells must be from the nearest lease line, and how much acreage must be assigned to a well in order to obtain a permit to drill a well. The acreage assigned to a proposed well is known as a “proration unit.” Well spacing and density rules were developed by the Commission after it was given jurisdiction over oil and gas operations in Texas in the early days of the oil industry, principally because of unregulated drilling in the East Texas Field. Because of unregulated drilling in that field, wells were being drilled that were not necessary for the efficient development of the field, and oil prices plummeted. The Commission was also given authority to “prorate” production from a field — that is, to limit production, and to allocate or “prorate” the specified limit of production from a field among the wells in a field. The stated purposes of spacing and density rules are to avoid waste and protect the correlative rights of producers in the field. Theoretically, field rules should designate a size for proration units that approximates the amount of acreage in the field that can be efficiently drained by a single well.

The field rules proposed by EOG would provide:

The Pennsylvania Department of Environmental Protection (PDEP) on Monday ordered EOG Resources to suspend all drilling operations in Pennsylvania pending investigation of an EOG well blowout on June 3 in Clearfield County, Pennsylvania. EOG had previously said it planned to drill 40 wells in the Marcellus Shale in 2010, and it not operates about 265 wells in Pennsylvania. The blowout shot gas and drilling mud and some 36,000 gallons of frac fluid 75 feet into the air. There was no fire, and no one was hurt. The PDEP banned EOG from drilling for up to seven days and from using hydraulic fracturing techniques for up to fourteen days. EOG said the blowout appears to have been caused by leaking seals in a blowout preventer.

PDEP also ordered C.C. Forbes, a unit of oilfield services contractor Forbes Energy Services, a Canada drilling company, to stop all work on Marcellus Shale wells. Forbes provided post-hydraulic fracturing services for EOG on the well that blew out. Forbes has idled to rigs in the Marcellus Shale.

This is the second time PDEP has banned an operator from drilling wells in the Marcellus Shale.  Previously, PDEP banned Cabot Oil and Gas from conducting hydraulic fracturing operations in Susquehanna County after three spills of a chemical used in hydraulic fracturing at Cabot wells. PDEP also fined Cabot $56,650 and ordered the company to submit a new Pollution Prevention and Contingency Plan and Control Disposal Plan for its wells.

The Texas Department of State Health Services issued its report on results of blood and urine samples taken from 28 residents of the tiny town of Dish, in Denton County, Texas. The report concludes that there is no evidence from those tests that the residents have elevated levels of airborne toxins in their bodies. 

As has been widely reported, the Mayor of Dish has been complaining that oil and gas operations around the town have resulted in exposure to airborne contaminants and health problems among citizens in the town. The town commissioned an air quality survey by a company named Wolf Eagle Environmental, which reported in December 2009 that the town “continues to show high levels of atmospheric VOCs known to have both carcinogenic and neurotoxin capabilities in concentrations that exceed TCEQ ESLs. High atmospheric concentractions of Methane were confirmed at various locations in both the August 2009 and December 2009 Air Quality Studies performed by Wolf Eagle.” The town also conducted a health survey of its citizens, and the survey results were analyzed by Wilma Subra, a Louisiana chemist, for Earthworks’ Oil and Gas Accountability Project. Ms. Subra’s report concluded that a significant number of residents reported health effects associated with toxics measured in excess of TCEQ screening levels, and it recommended that the Texas Department of State Health Services (TxDSHS) test the blood of community members.

TxDSHS reported that, although elevated levels of volatile organic compounds were found in some of the blood samples, “the pattern of VOC values was not consistent with a community-wide exposure to airborne contaminants, such as those that might be associated with natural gas drilling operations,” and could have come from other sources such as cigarette smoking, metal cleaners, degreaser and lubricants. TxDSHS also tested water samples from residents’ homes and found one home with an elevated level of a chemical derived from chlorine added to drinking water. The TxDSHS report cautioned that its investigation was limited to a one-time sampling event, that VOC’s stay in the body for only a short time, so the tests could reflect only recent exposures and not historical exposures.

Gasland is a film documentary about the dangers caused by hydraulic fracturing of gas wells being drilled in shale plays across the U.S. It won a Special Jury Prize at the Sundance Film Festival this year. It was filmed by Josh Fox, whose family owns land in Pennsylvania that is in the Marcellus Shale Play. Gasland is now being screened across the country.

Josh Fox was recently interviewed about his film on the PBS program NOW. The film asserts that frac’ing of wells has caused underground aquifers to be charged with methane in Pennsylvania and Colorado and poses severe risks of contamination to the water supply. Josh Fox notes that hydraulic fracturing is exempt from federal regulation, and he advocates for passage of the FRAC Act now before Congress that would give the EPA jurisdiction over hydraulic fracturing.

The comments about the NOW story posted on its website evidence the growing controversy over frac’ing.

Newfield Exploration has reported that it is drilling horizontal wells with “super extended laterals” in the Woodford Shale in Oklahoma — wells with laterals exceeding 5,000 feet. Newfield has so far drilled 14 super-extended lateral wells, with an average length of 9,000 feet. Those wells had an average gross initial production rate of approximately 9 MMcfe/day.

ConocoPhillips reported that it has completed the drilling of four horizontal wells in the Eagle Ford shale play, in its “liquids-rich” core. The first of these wells was put on production in March and flowed at an initial rate of 3.8 mmcf/day and 1,200 barrels/day of condensate.

All of the new shale gas production continues to put downward pressure on gas prices. Natural gas futures for June delivery fell 36.8 cents, or 8.5 percent on Thursday, April 29 on NYMEX. So far this year, natural gas futures have fallen 29 percent. The Energy Information Administration reported that the supply of gas in storage increased  by 83 Bcf for the week ended April 30. Gas in storage is 315 Bcf above the 5-year average.

The Park Foundation has submitted a resolution for consideration at ExxonMobil’s annual meeting urging ExxonMobil to prepare a report on the environmental impact of fracturing operations and what can be done to reduce or eliminate environmental hazards caused by hydraulic fracturing.  The proposal, and ExxonMobil’s response, provide a good summary of the state of the debate in the U.S. over potential environmental impacts of hydraulic fracturing. I have reproduced the entire statement from Exxon’s proxy statement below.

An interesting article by Joe Carroll of Bloomberg News explores the problems faced by South Texas Ranchers seeking to require cleanup of old oilfield contamination. These problems are widespread in Texas and in my opinion the Texas Railroad Commission is ill equipped to address the problems.

An interesting case has recently been filed in Louisiana challenging the authority of the Louisiana Department of Conservation to approve pooled units containing multiple wells. In Gatti et al. vs. State of Louisiana, et al., Number 589350, Division 23, filed in the 19th Judicial District Court in East Baton Rouge Parish, the plaintiffs sued the State Department of Conservation and several operators in the Haynesville field, including Chesapake, Encana, Exco, Conoco Phillips, Petrohawk, SWEPI, EOG, Questar, Forest and XTO, claiming that the Department of Conservation was routinely allowing the drilling of “alternate unit wells” on previously established units, in violation of Louisiana law. A copy of the petition may be found here. 

Gatti v. St of Louisiana.pdf.

Louisiana has a forced-pooling statute that allows an operator to propose to the Department of Conservation a unit for a well which, if approved, forces all mineral owners in the unit to pool their interests for the drilling and production of that well. According to the plaintiffs, this statute only authorizes the Department to approve units large enough to cover an area drained by one well. The practice in Lousiana for the Cotton Valley and Haynesville fields is to obtain orders for 640-acre units, and later obtain approval to drill additoinal “alternate unit wells” on those units. The suit contends that this practice is unfair to the owners of minerals and royalties in the unit, and violates state law. The suit seeks certification of a class action on behalf of all owners of mineral rights in Haynesville Zone in Louisiana. It seeks a declaration that the Department has no authority to establish a unit having an area in excess of the area drainable by one well, and that any such unit is “null and void.” The suit also seeks unspecified damages against the defendant companies.

The Bureau of Land Management has signed a settlement agreement in which it agreed to “suspend” oil and gas leases covering BLM lands in Montana until it has completed a review of the effect of oil and gas development on greenhouse gas emissions.

The settlement was entered in Montana Environmental Information Center, et al. v. United States Bureau of Land Management, Case No. 08-178-M-DWM, in the U.S. District Court for the District of Montana, Missoula Division, on March 11, 2010. The case was brought by citizens groups who contended that federal law required the BLM to consider the cumulative impacts of oil and gas development on the environment, and specifically the greenhouse gas emissions caused by oil and gas well drilling and production, before granting oil and gas leases on lands in Montana.

The plaintiffs’ petition contains some interesting facts:
