Since Abdelmoumen Ould Kaddour took over as head of Sonatrach in March, his background and history have come under intense scrutiny. While some industry participants hope that his commercial experience and attitude can revivify both Sonatrach and the oil and gas sector more generally, some controversial aspects of his past could be used to destabilise him and undermine his legitimacy. The focus of reports has been on his 2007 conviction for divulging state secrets, the business activities of his family, and his alleged French citizenship.
