Marcellus Shale drilling becomes more efficient

When David Dewberry landed in Pennsylvania in 2010, the veteran of the migratory worldwide oil-and-gas workforce said he required more than a month to drill a typical Marcellus Shale natural gas well.

On Dec. 4, a crew under Dewberry’s direction dug into the mountaintop of a state forest near here with a diamond-studded drill bit. Dewberry reckons it will require only 16 days to finish drilling the well’s full length, more than 21/2 miles.

“Since I came up here three years ago, it’s 200 percent better,” said Dewberry, who manages this Lycoming County site in Loyalsock State Forest for Seneca Resources Corp.

The well not only will require half the time to drill, the bore will extend farther horizontally than older wells. And, if it performs like other wells in the area, it will produce a staggering amount of gas.

When it’s done, the towering rig will crawl 20 feet and begin drilling another well. Seneca plans to complete nine wells in an assembly-line fashion on this site, which is the size of five football fields.

“We’ve become so much more efficient,” Dewberry said.

Marcellus Shale exploration companies are drilling bigger wells in less time at less cost, and they are producing more natural gas than ever in Pennsylvania.…
