Study: Utica Shale Larger Than Previous Estimates
by Karen Boman|Rigzone Staff| July 16, 2015
The size of the Utica shale play’s technically recoverable resources is larger than previously thought, a recent study by West Virginia University (WVU) has found.
WVU found that the Utica play contains technically recoverable resources of 782 trillion cubic feet (Tcf) of natural gas and around 1.9 billion barrels of oil. That’s higher than the U.S. Geological Survey’s (USGS) 2012 estimate of technically recoverable resources at 38 Tcf of gas and 940 million barrels of oil.
The study results indicate that the Utica – which spans West Virginia, Kentucky, Pennsylvania, Ohio and New York – is comparable to the Marcellus shale play in terms of size and potential recoverable resources. The Marcellus is the large U.S. shale play and second largest shale oil and gas play in the world.
Most of the Utica play lies beneath the Marcellus. The interval between the Marcellus and deeper Utica plays ranges from 4,000 feet in Ohio to more than 6,500 feet in West Virginia. The drilling depth of the Utica ranges from less than 4,000 feet in Ohio to more than 12,000 feet in West Virginia, which is over two miles below the surface.
The results of the Utica Shale Play Book Study, a two-year geological study undertaken by the Appalachian Oil and Natural Gas Research Consortium, a program at WVU’s National Research Center for Coal and Energy, were presented at a July 14 workshop in Canonsburg, Penn.
“The revised resource numbers are impressive, comparable to the numbers for the more established Marcellus shale play, and a little surprising based on our Utica estimates of just a year ago which were lower,” said Douglas Patchen, director of the consortium and well-known expert on the Appalachian Basin.
