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.
