Drillers share keys to boosting efficiency at DUG East conference in Pittsburgh
Building more pipelines out of the Marcellus shale won't bring enough relief to natural gas companies struggling with low prices, an analyst told industry leaders gathered in Pittsburgh on Wednesday.
Demand from power plants and other big customers won't keep pace with all the new supply coming out of the region over the next few years until exports of liquefied natural gas ramp up, said Kathryn Downey Miller of Denver-based BTU Analytics.
“Don't expect demand to increase greatly until LNG shows up in 2019 to 2020,” she told the seventh annual Hart Energy Developing Unconventionals DUG East conference, Downtown.
Until then, the producers with the best locations for drilling and lowest costs have the upper hand, Miller and others said.
“Can you control your costs ... and have a sufficiently sized balance sheet to offset the bad with the good?” Paul Morgan of Stratus Advisors said.
Leaders of several companies made their case for why they are in the best position. Despite the large size of the Marcellus and Utica shales, Derek Rice, executive vice president of Cecil-based Rice Energy, estimated “about 20 percent of the fairway is economic.”
Range Resources Corp. and Consol Energy Inc. touted well-placed lease locations that allow them to hit multiple layers of rock — Upper Devonian, Marcellus and Utica — from a single well pad.
“There's a lot of efficiencies to having them stack up like that,” said Jeff Ventura, CEO of Fort Worth-based Range.
State College-based Eclipse Resources Corp., a relative newcomer to the shale, is focused on the Utica in Ohio. It found success by extending the horizontal length of its wells by more than 1,000 feet during the past year and using more sand in fracking while cutting costs by 23 percent, said CEO Benjamin Hulburt.
“We think we're far from over in optimizing this,” he said.
Ryan Horvat, an analyst with New York-based ITG Investment Research, said analysis of wells shows per-foot production drops very slightly as those horizontal “laterals” are extended, so “it makes sense to drill out as far as you can.”
Companies have found limits, though.
“We're more comfortable with about 10,000 feet,” said Craig Neal, a vice president at Consol who said the Cecil-based gas and coal company extended one well more than 14,000 feet at Pittsburgh International Airport. The average in the Marcellus is about 5,000 feet.
Malcolm Yates, a manager for fracking contractor Schlumberger, raised a note of concern over longer wells drilled more closely together and drilling into different horizons from pads that have older Marcellus wells.
Such practices raise the risk of crossing paths with or diminishing results from older wells, he said. “We need to understand the consequences.”
Companies are experimenting with how much space to leave between wells. Several companies said they leave 500 to 750 feet, depending on the formation.
“That's something we're trying to figure out. You need to see, how much are these wells communicating?” Rice said.
