Pa. stops company’s drilling after accident
The order against EOG Resources Inc. will remain in place until DEP can finish its investigation.

HARRISBURG — Pennsylvania regulators halted work Monday at dozens of unfinished natural gas wells being drilled by the company whose out-of-control well spewed out explosive gas and polluted water for 16 hours last week.
The order against Houston-based EOG Resources Inc. will remain in place until the Department of Environmental Protection can finish its investigation and until after the company makes whatever changes may be needed, Gov. Ed Rendell said.
The order stops EOG from drilling and hydraulically fracturing wells. It affects about 70 unfinished EOG wells into the gas-rich Marcellus Shale formation.
Another concern was the apparently bungled attempts to notify the right emergency-response officials about the accident. Fines are likely, said Environmental Protection Secretary John Hanger.
Nobody was hurt in Thursday’s blowout in a heavily forested section of north-central Pennsylvania.
The accident shot highly pressurized gas and wastewater as high as 75 feet. The gas never caught fire, but state officials had worried about an explosion and ordered electrical service to the area cut before specialists secured the well at about noon Friday.
About 35,000 gallons of wastewater have been pumped into holding tanks so far, the company said.
Monitors in a nearby spring show signs of pollution, although Hanger said the spring is in such a rural area that it is not viewed as a public health hazard. Officials say they have detected no pollution in larger waterways that feed public water supplies.
The state says the company is cooperating and is supportive of the stop-work order.
Gary L. Smith, vice president and general manager of EOG’s Pittsburgh office, said the company regrets the accident and would continue to work with Pennsylvania officials.
“After the investigations are complete, we will carefully review the findings with the goal of enhancing our practices,” Smith said.
“When all outstanding issues are resolved, we look forward to resuming full operations in Pennsylvania,” Smith added.
DEP officials said the well’s blowout preventer failed, and they were investigating whether the failed equipment was the primary cause.
A blowout preventer is a series of valves that sit atop a well and allow workers to control the pressure inside.
Hanger and EOG said the blowout preventer had been tested successfully by the company on Wednesday morning.

Pa. inspectors looking into gas well emergency

HARRISBURG — State environmental regulators worked Sunday to get to the bottom of what caused a natural-gas well to spew explosive gas and polluted water for 16 hours last week before it could be brought under control.
Neil Weaver, spokesman for the Department of Environmental Protection, blamed a failure on the well’s blowout preventer, a series of valves that sit atop a well and allow workers to control the pressure inside. Investigators are trying to figure out what caused the malfunction.
The blowout is the latest in a string of accidents connected by regulators to the rapidly growing pursuit of the rich Marcellus Shale gas reserve that lies beneath much of Pennsylvania.
It seems likely the Pennsylvania blowout will enter the debate in the Capitol, where legislators are battling over the merits of an extraction tax and tighter regulations on an industry that has spent several billion dollars and drilled more than 1,000 wells in Pennsylvania in just a couple years.
State Rep. David Levdansky, D-Allegheny, said such oil problems could bring increased interest in a moratorium on leasing public land for gas drilling and a severance tax that could largely fund existing environmental protection and cleanup programs. Levdansky is a leading environmental advocate.
Weaver declined to discuss whether investigators have found anything so far or whether well driller EOG Resources Inc. of Houston committed any violations that could lead to fines or any other penalties.
An EOG spokeswoman said Sunday the investigation into the cause is ongoing, and the company had no light to shed on the blowout.
Crews evacuated the site Thursday night and didn’t regain control over it until just past noon Friday. No one was injured, the gas didn’t explode and polluted water didn’t reach a nearby waterway, officials said.
The blowout sent highly pressurized gas and polluted water 75 feet into the air. Huge tanks were required to cart off chemical- and mineral-laced water collected on the grounds of the private hunting club where the well had just been drilled.
