BP has confirmed that its head of North Sea operations is to move on to a new role within the company.
A replacement has not yet been named for Mark Thomas, who has been in the position of regional president since 2015.
BP said a full transition process would take place between Mr Thomas and his successor.
It is understood Mr Thomas will not be leaving the energy giant but is poised to move from his station in Aberdeen.
Since taking on the job, Mr Thomas has overseen developments including the sale of the major Forties pipeline system to Ineos and recent news of the Capercaillie and Achmelvich oil and gas discoveries in the North Sea.
Mr Thomas replaced Trevor Garlick when he left the position in 2015.
