Earlier this year, geologists were telling us that the Marcellus Shale is huge — that it could supply enough gas to supply the entire USA for two full years. Experts now think that estimate may be incorrect: it could contain seven times that much! As reported in Forbes:
Penn State University geoscientist Terry Engelder said in a phone interview Monday that he now estimates 363 trillion cubic feet of natural gas could be recovered over the next few decades from the 31-million-acre core area of the Marcellus region…
“It has the potential to be the biggest gas field in the United States,” John Pinkerton, chairman and chief executive of Range Resources Corp., said last week in an interview at the Fort Worth, Texas-based company’s office in western Pennsylvania.
Engelder first presented his new numbers in Pittsburgh last week at a conference on Appalachian gas sponsored by the energy information firm Platts. He said he based his revised estimate on new figures from Chesapeake Energy Corp., the nation’s largest natural gas producer.
