Chief Technology Officer

Mr. John W. Sweeden joined Hefner Energy in July 2017 as Chief Technology Officer and Chief Information Officer responsible for data systems and architecture.

John previously was Vice President, Finance and Reservoir Engineering from 2014-2017 for Cosmo Energy, a $50mm mineral and royalty company, where he was responsible for investments and developing internal systems to manage 3,400 net acres across 700 sections and 500 producing wells in Oklahoma and Texas.

While at Cosmo John spearheaded the purchase of the Poteet property, Continental Resources’ flagship SCOOP asset.  The Poteet Unit’s 10 wells’ production peaked at over 145 million cubic feet of gas per day and 3,200 barrels of oil per day with an average lateral length of less than 7,500 feet.  Since 2015, the Poteet Unit has produced more than 40 billion cubic feet of gas and 400,000 barrels of oil.

Prior to Cosmo, John was New Ventures Engineering Manager for Questar Corporation (now NYSE:D) from 2012-2014 where he was responsible for a technical team which acquired $250mm of producing assets in the Rockies. He also served as Production Engineer for Newfield Exploration (NYSE:NFX) during the formative years of their now world-class SCOOP Woodford key asset from 2011-2012.

John holds his Bachelor of Science in Petroleum Engineering from the University of Oklahoma and is a graduate of OU’s Energy Executive Management Program. He is a distinguished lecturer at Oklahoma City Law School and National University of Colombia.

John’s diverse experience extends beyond traditional oil and gas engineering and A&D.  John is an expert in advanced data systems and architecture which drives Hefner Energy’s cloud based analytics and machine learning efforts.  John has worked directly beside DrillingInfo, Oseberg, and Silicon Valley Software Group (SVSG) to determine best practices for data architecture in the oil and gas industry.
