Shell's head of exploration Ceri Powell will leave her role next month to move on to another leading position with the supermajor.
Powell will depart on 13 February after seven years and become managing director of Brunei Shell Petroleum the following month, a Shell spokeswoman told Upstream, confirming an earlier report from Reuters.
Powell, a geologist educated in Wales, joined Shell in 1994 in Malaysia. She will be replaced by current upstream strategy vice president Marc Gerrits.
The internal moves are part of a broad reshuffle of senior positions following the completion of Shell's $54 billion acquisition of BG Group last year.
Under the changes, Shell chief financial officer Simon Henry is also preparing to make an exit from the Anglo-Dutch group after more than 30 years with the company. Henry will be replaced current director and member of the executive committee Jessica Uhl. He will hand over duties on 9 March.
