FAIRMOUNT TWP. – Having drilled 8,100 feet straight down into the earth beneath the Buda 1H Well Pad, Encana Oil & Gas is now preparing to begin the horizontal leg of the first Marcellus Shale natural gas well in Luzerne County.

Company officials on Thursday provided a tour of the well pad off state Route 118, out behind Ricketts Glen Hotel, explaining various parts of the drilling operations and noting extra safety measures employed, given the proximity to wetlands.

As an automatic pipe handler lifted 40-foot sections of drill pipe, each weighing about 650 pounds, from a storage area on the ground onto the drill rig, Encana operations engineer Joel Fox explained the purpose of some of the equipment used on-site.

“This is one of the modern rigs with an automated pipe handler. … In the old days, you had roughnecks out there handling that pipe, two or three guys muscling around, fighting that pipe. This system’s a lot safer,” Fox said.

Joining Fox were Encana operations engineer Ashley Lantz and environmental health and safety coordinator Jarrett Toms.

Toms said there have been no health or safety related issues on-site since the drilling began last month.

Fox showed some large steel pipe, called casing, stored there. Surface casing is run down into the well bore about 425 feet and is “what provides the protection of your fresh-water aquifers. That’s been run already and cemented,” he said.

He also showed intermediate casing, which is run down to 2,150 feet. The intermediate casing is cemented inside the surface casing, and cement is also pumped around the exterior pipe to prevent gas from seeping up the outside of the casing and into ground water.

A third string of steel casing – production casing – will be run into the total depth of the well after horizontal drilling is complete. The horizontal drilling begins by drilling a curved path from a vertical well bore to 90 degrees over a 900-foot span.

“The pipe is pretty flexible. It’s stiff and strong, but it will bend,” Fox explained.

During drilling, rock and drill bit cuttings must be removed from the well bore.

Fox pointed out pallets full of bags of chemicals that are mixed with synthetic food-grade drilling oil to make the drilling mud.

“It looks and feels like baby oil,” he said. Emulsifiers are added to the oil and water to make the mud viscous so it will carry the drill cuttings to the surface of the well for removal.

When drill cuttings come up, they’re cleaned, mixed with sawdust, stored in covered containers until tested by the state Department of Environmental Protection and then hauled off to a landfill.

Fox also noted there is no reserve pit to hold the cuttings at the Buda site.

“This is an entirely closed system. In other words, there are no open pits that you hear people talk about a lot in the newspaper. All fluids are contained in tanks; drill cuttings, fluid is all in tanks,” Fox said.

“We consulted with DEP, and because we’re in a wetlands area, a closed system made a lot of sense,” Fox said, even though a closed system is more expensive to operate than using a reserve pit.

It also made sense to use a closed system at the site because the water table is high in the area, so a pit could not be dug very deep, he said.

To protect the ground from potential spills of any fluids on-site, the part of the well pad under and around the drill rig and all of the tanks and equipment is covered with liners hung over berms that look like barricades, Fox explained.

“We call these duck ponds. If something gets spilled, it stays in there. And we have what looks like a large Shop-Vac device. So as soon as any fluid or rainwater gets on that liner, we can suck it up like a Shop-Vac in your basement,” he said.

Fox also pointed out four monitoring wells the company drilled at strategic locations between the site and Ricketts Glen Hotel, which has the nearest water well.

Also on-site are five trailers for office space and to house some staff. There are five people with the drilling contractor – Horizontal Well Drillers – plus two to five Encana employees, drilling specialists and contractors on-site at all times.

It should take 10 days to two weeks to drill the 3,500- to 4,000-foot horizontal leg of the well, also called the lateral, in a southeast direction. The company uses computerized equipment near the drill bit to make sure the well bore is going exactly in the direction the engineers want it to, Fox said.

“It’s like a GPS on the (drill) bit,” he said.

A provision to require disclosure of all chemicals used in fracturing Marcellus Shale to extract natural gas could wind up as part of the scaled-down national energy bill the U.S. Senate might consider soon.

Sen. Bob Casey said he convinced Senate Majority Leader Harry Reid to fold disclosure provisions of his Fracturing Responsibility and Awareness of Chemicals Act into the energy bill.

“It’s a great breakthrough,” he said. “It’s a substantial step forward. … It gives people information they wouldn’t have otherwise about what’s happening underneath their property.”

Senate leaders are hoping to pass the bill before the summer recess Aug. 6, after realizing they did not have the votes to pass a more comprehensive energy bill. Even if the smaller energy bill gets through the Senate, the House would have to pass it before President Barack Obama can sign it. Neither is assured.

Industry groups said the fracturing chemicals are already well known to the public and state regulators, and further disclosure would harm the development of natural gas.

“We fundamentally believe that regulation of hydraulic fracturing is best addressed at the state level, and we have been unable to reach a consensus with congressional advocates on how this program would be overseen by the federal government,” America’s Natural Gas Alliance said in a statement.

Congress and the federal Environmental Protection Agency are studying whether the chemicals used in hydraulic fracturing of shale contaminate drinking water.

Energy In Depth, an industry group, argues regulation should be left to states, which “have effectively regulated hydraulic fracturing for over 40 years with no confirmed incidents of groundwater contamination associated with (fracturing) activities.”

At public meetings on gas drilling, local residents regularly dispute the claim.

Though the industry argues the chemicals it uses are well known, a Times-Tribune investigation determined that DEP scientists who analyzed spilled fracturing chemicals at a Susquehanna County well site in September found 10 compounds never disclosed on the drilling contractor’s material safety data sheet.

None of the 10 was included in a state Department of Environmental Protection list of chemicals used in fracturing, a list developed by the industry. When DEP posted a new list earlier this month, none of the 10 was on it.

Mr. Casey dismissed the industry criticism.

“That’s why I called it a substantial step forward, if they’re attacking it,” he said. “If they’re feeling that this is giving information to people that they are reluctant to disclose, that’s why I think it’s an important change, and it’s progress on an issue that some would have thought would have taken years to get done.”

Mr. Casey’s legislation would amend the federal Emergency Planning and Community Right-to-Know Act, which requires employers to disclose what hazardous chemicals they use.

The amendments would require:

– Well-drilling operators to disclose to state regulators and the public a list of chemicals used in fracturing, commonly known as fracking. The requirement would cover chemical constituents but not chemical formulas whose manufacturers are allowed by law to keep the formulas secret, according to Mr. Casey’s office.

– Disclosure to be specific to each well.

– Disclosure of secret formulas or chemical constituents to doctors or nurses treating a contamination victim in an emergency.

– An end to thresholds for reporting chemicals normally required by law so all amounts of chemicals are reported.

In an analysis of the legislation, Energy In Depth said it would “chill” investment in innovations in fracturing and place “unrealistic burdens” on natural gas producers by requiring them to disclose secret chemical compounds whose composition they legally can know nothing about.

In an interview, DEP Secretary John Hanger said he welcomed the federal legislation, argued Pennsylvania already requires more disclosure than his bill and believes companies should disclose the volume and mix of chemicals they use in fracking.

The initial events polluted a wetland and caused a fish kill in Susquehanna County.

By Rory Sweeneyrsweeney@timesleader.com

Cabot Oil and Gas has been issued a letter of violation for two liquid-gel spills last week at the company’s Heitsman natural-gas well pad in Susquehanna County, the state Department of Environmental Protection announced on Tuesday.

The spills of about 8,400 gallons, which polluted a wetland and caused a fish kill in Stevens Creek, were followed up by a third spill at the site on Tuesday morning, according to DEP spokesman Dan Spadoni.

A hose burst, according to DEP, and released about 420 gallons of the same lubricant. A catch basin retained most of it, Cabot spokesman Ken Komoroski said, but it’s unknown what happened to 10 gallons.

He said he was unaware of the spills causing any environmental damage, but acknowledged that a dam created to block the contaminant caused flow problems and that DEP noticed “the minnows downstream were distressed and/or swimming erratically.”

“We think that it’s important to residents that no contaminants from the spill have compromised Stevens Creek,” he said.

The spilled material, known as LGC-35, suspends sand in water to fracture rock in the gas-drilling process used in the Marcellus Shale region.

LGC-35 is a “potential carcinogen,” according to its Material Safety Data Sheet, and can cause eye, skin and respiratory irritation, along with “central nervous system effects,” such as dizziness and headaches.

Komoroski said the drilling contractor, Halliburton, has since revised the safety sheet to exclude the carcinogenic reference because the potential cancer-causing agent is a “potential contaminant” to the gel, not part of its formula. Halliburton told Cabot the contaminant wasn’t present in the spilled batches, but Cabot is performing its own testing to confirm that, Komoroski said.

He added that Cabot feels Halliburton should have been cited for the spill. Halliburton had flushed the wetlands with clean water and collected the effluent before the third spill, Spadoni said, and it won’t be known whether the land needs to be excavated until results from soil samples are announced. “I would anticipate that would be done fairly soon,” Spadoni said.

Cabot has 10 days to respond to the violation notice with how it plans to further clean the affected area and prevent future spills. DEP may assess a civil penalty in the case, for which Komoroski said Cabot would seek compensation from Halliburton.

Firm with substantial holdings in Luzerne County taking next step toward exploration.

By Rory Sweeneyrsweeney@timesleader.com

WhitMar Exploration Co., the only gas-drilling company so far to have leased substantially in Luzerne County, plans to begin drilling by the middle or latter part of next year, according to the company’s president.

“Right now, we’re just filing for some permits for two, possibly three wells we want to drill,” said Whit Marvin, who heads the Denver-based company. “We do plan on drilling it and testing it for the Marcellus Shale.”

Throughout 2009, WhitMar has leased more than 22,000 acres in, among other places, Fairmount, Ross, Lake, Lehman, Union, Hunlock, Huntington and Dallas townships with little money upfront by offering landowners a contractual guarantee to begin drilling within two years.

The contract also guaranteed permitting within the first year, and Marvin said that process is on track. The company is filing for drilling and water-consumption permits from the state Department of Environmental Protection and the Susquehanna River Basin Commission, and is looking into any other permits it might need, he said.

From there, the company will negotiate with the individual landowners about siting for the well pads and gaining access to them, he said.

Much of that will be based seismic testing that’s being done, the results of which Marvin expects before the end of the year. “In essence, you’re using ultrasound. You’re looking for anomalies under the surface … that would be attractive to drill into,” he said. “We can make some geologic interpretation, (but) it’s definitely not an exact science.”

A drilling contractor hasn’t been hired yet, he said, but the company has begun work elsewhere in the shale. It has leased “large blocks” in Lycoming, Wayne and Susquehanna counties, as well as in some counties in New York’s southern tier, he said. Of that, wells are being drilled in Chemung County, N.Y., and preparations for drilling are being made in Susquehanna and Lycoming counties, he said.

In Lycoming County, the industry is moving so fast that companies needing and offering services aren’t able to connect, according to Jeffrey Lorson, an industrial technology specialist at the Pennsylvania College of Technology.

For that reason, the college and a group of organizations interested in the industry are sponsoring a business-networking expo today. Lorson, who heads the college’s Marcellus Shale Education & Training Center, said about 130 vendors are scheduled to be at the free-admission event at the Hughesville Fairgrounds.
