The board of French seismic specialist CGG has appointed Sophie Zurqzuyah to replace Jean-Georges Malcor, who had planned to step down as chief executive after the completion of the company’s extensive restructuring.

Zurqzuyah’s posting should become effective after approval at its annual general meeting on 26 April, according to CGG.

The new chief executive joined the company in 2013 after 22 years in the oil services industry, including time with US-listed giant Schlumberger.
