Pat O’Bryan will become CEO of MDU Resources Group Inc.’s Fidelity Exploration & Production Co., effective March 1, MDU said in a statement. He will also retain his current position as president.

O’Bryan will succeed J. Kent Wells, who announced his Feb. 28 retirement from the positions of Fidelity CEO and vice chairman. Wells also indicated that he will resign as a director of MDU at that time.

MDU announced in November that it plans to market Fidelity, but the company delayed that process in light of the recent volatility of oil prices.

O’Bryan became president of Fidelity in July 2014, after joining the company in 2011 as vice president of drilling and completions. He has 26 years of experience in the oil and gas business, including executive and asset general management, drilling engineering and technology management, production and reservoir engineering supervision. Before joining Fidelity, O’Bryan held vice president positions in drilling and completions and productions at BP Plc.
