Welcome to the Penn State Marcellus Center for Outreach and Research

The Marcellus Center for Outreach and Research (MCOR) is Penn State's education and research initiative on unconventional gas plays. We serve state agencies, elected and appointed officials, communities, landowners, industry, environmental groups and other stakeholders. We are committed to expanding research capabilities on technical aspects of developing this resource and to providing science-based programming while protecting the Commonwealth's water resources, forests and transportation infrastructure. MCOR is internally funded by the College of Agricultural Sciences, the College of Earth and Mineral Sciences, Penn State Institutes of Energy and the Environment and Penn State Outreach.


News Release: In 2014, U.S. crude oil and lease condensate proved reserves increased to 39.9 billion barrels—an increase of 3.4 billion barrels (9.3%) from 2013. U.S. proved reserves of crude oil and lease condensate have risen for six consecutive years, and exceeded 39 billion barrels for the first time since 1972.1 Proved reserves of U.S. total natural gas2 increased 34.8 trillion cubic feet (Tcf) to 388.8 Tcf in 2014. This increase (9.8%) boosts the national total of proved natural gas reserves to a record-high level for the second consecutive year.
Sustained low prices for oil and natural gas are anticipated to reduce the reserves in EIA’s next report (for year-end 2015). Lower prices have curtailed drilling and made recovery economics more challenging. Although resource estimates are not necessarily reduced by lower prices, the calculation of proved reserves is sensitive to price. :

Penn State Royalty and Decline Curve Web App

By looking closely at actual natural gas production of 5,492 horizontal shale wells, a cumulative production model was assembled to create royalty estimates and better decision making tools for businesses and individuals.
