New Age has separated the roles of chairman and chief executive in a top-order shake-up.
Founder Steve Lowden remains chairman and David Stoopin has been appointed chief executive.
Mr Stoopin has been with New Age since 2008, having previously worked for BP and Premier Oil.
While at BP, David’s roles included commercial manager for BP’s Angolan developments, as well as M&A strategy manager.
Mr Lowden said: “David has played an integral part in the successful development of New Age, which now has production from multiple oil and gas fields across Africa and Kurdistan.
“His leadership ability, commercial acumen and deep technical knowledge position him well in his new role as CEO and I look forward to continuing to work closely with him.”
New Age, founded in 2007, produces from multiple oil and gas fields across Africa and Kurdistan.
It plans to ramp up production to over 70,000 boepd by 2022.
