The Marcellus Shale Gas Resource, Appalachian Basin, USA - the play, geology, seismic/geophysics,  drilling, completion/fracking, engineering, geosteering, horizontal well placement, environmental and regulatory, economics, pipelines, markets and energy supply

The Marcellus Shale is believed to have technically recoverable gas reserves approaching 400 TCF, making it one of the largest shale gas resources in the world. Based upon 2015 production, the Energy Information Administration ranked the combined Marcellus and Utica plays in the Appalachian Basin as the third largest producing region in the world. Daily Marcellus and Utica production is projected to be above 35 BCF of gas per day by 2020. These two plays have the highest estimated ultimate recoveries from wells among all U.S. natural gas plays resulting in the lowest breakeven prices.

Cabot is the second largest producer in the Marcellus play and has drilled more than 500 horizontal wells since 2009, completed more than 10,000 hydraulic fracture stages, and produced more than 2.5 trillion cubic feet of gas from the Company's acreage position. Cabot has invested more than 5 billion dollars in this natural gas resource and hundreds of millions of dollars have been paid to landowners, businesses and governments as royalties, operational costs, fees and taxes.

Today's presentation will also discuss the distinct structural geology styles that characterize the Marcellus reservoir. The middle Devonian formations display an intense combination of compressional, extensional and possibly strike-slip structural features, compounded by salt movement and related deformation. The interpretation of vertical changes in structural style and stress patterns indicate that the outcropping upper Devonian Appalachian Plateau strata are detached from the underlying middle Devonian and older strata beneath northeastern Pennsylvania and perhaps elsewhere in the Appalachian Basin..
