Mack Blackford
Managing Partner
Mr. Blackford has more than 15 years of experience in upstream energy. He has extensive experience in both public and private equity backed companies evaluating acquisitions, generating prospects, and developing conventional and unconventional plays across nine basins and seven states. Additionally, he has focused much of his career in bridging the gap between geology and reservoir engineering, making the latter an emphasis in recent appraisals. His evaluation effort assisted in a $600MM+ acquisition in 2008 and he deployed $100MM over the course of the year as asset lead, drilling 50 vertical wells in Louisiana prior to leading QEP Resources’ Haynesville Shale development effort. While at Panther Energy II, he served as Exploration Manager and helped develop Panther II’s Delaware Wolfcamp acreage across three counties in west Texas which ultimately sold for over $850MM in Q1 2017.
Most recently Mack served as VP of Exploration at Olifant Energy. There he was responsible for evaluating opportunities in Lower 48 focusing his efforts outside of the Delaware Basin. Prior to Olifant, Mack worked as an exploration and development geologist for QEP Resources, Cimarex Energy, Nemaha O&G, and Panther Energy II. He holds a B.S. and M.S. in Geology from Oklahoma State University.
