CANONSBURG, PA.–More than 240 flights carrying some 22,000 passengers move through the runways and concourses of the Pittsburgh International Airport every day. But below the PIT complex are the prolific Marcellus and Upper Devonian shales, and potentially, the deep dry Utica shales that underlie western Pennsylvania. In 2013, CONSOL Energy entered a partnership with the Allegheny County Airport Authority (ACAA) to develop natural gas reserves beneath 9,263 acres on PIT grounds. A dry Utica test well has been approved by federal, state and local authorities, and will replace a Marcellus well in the 47-well PIT development plan. The initial plan calls for six horizontal well pads. Dictated by topographical and environmental features, and the need to avoid obstructing growth of airport surface facilities, the unique location requires constructing complex wellbore geometries with high buildup curves and long laterals.
