Southwest Appalachia Operations
In late 2014 and early 2015, we closed two transactions to acquire natural gas and oil assets in West Virginia and southwestern Pennsylvania targeting the Marcellus, Utica and Upper Devonian Shales. Southwestern had a total of 299 horizontal and 4 vertical wells that the Company operated and were on production as of December 31, 2016.

In 2016, we invested approximately $288 million in Southwest Appalachia to spud 17 wells, complete 17 wells and place 18 wells to sales. In 2016, of the 18 wells brought to sales, 15 were drilled and completed by Southwestern, of which 14 targeted the Marcellus Shale. The Marcellus wells had an average completed well cost of $5.4 million per well and an average horizontal lateral length of 5,316 feet.
