Unconventional Reservoirs
EQT is at the forefront of tapping into unconventional reservoirs for what were once unrecoverable energy resources.
Whether drilling deep into Huron or Marcellus Shale or tapping into more shallow coalbed methane,
EQT applies the latest, most efficient drilling technologies to effectively and economically respond to
the nation’s call for new energy supply.
EQT Production’s drilling has been concentrated in three major plays: Marcellus, Huron/Berea and coalbed methane.
EQT drills low risk development wells into reservoirs that are known to be productive.
Marcellus
Geologists familiar with the Appalachian Basin have known for years about the Devonian black shale called
the Marcellus. The Marcellus Shale is organically rich shale that lies nearly a mile or more beneath the
surface throughout much of Ohio, West Virginia, Pennsylvania and New York. The Marcellus Shale, a "super giant"
gas field, has enough resources to meet the energy needs of every American home, business and industry
for an estimated 20 years, all on its own. With approximately 520,000 acres and 2.9 Tcfe of proved
reserves, EQT is a leading player in the Marcellus Shale. EQT plans to drill 100 Marcellus wells in 2011.
Huron/Berea
EQT has recently focused drilling on the Huron/Berea play, where the company has approximately 2.7 million
acres and 2.2 Tcfe of proved reserves, and 7.4 Tcfe of 3P reserves. The company drilled 236 horizontal
wells in the Huron Shale in 2010.
