Has over 35 years experience in the Oil and Gas Industry, mainly with ELF and for over half of that time his focus was Africa. As VP Africa Exploration, during the period 1987-1993, he was instrumental in positioning ELF in the deep offshore exploration of the Gulf of Guinea leading to the giant discoveries in Angola (Girasol, Dalia…) and in Nigeria (Bonga, Usan…). He was also involved in several other large discoveries (Amenan in Nigeria, Cobo-Pambi in Angola, Nkossa in Congo) and in the development of complex fields which needed multidisciplinary work. In 1993 he became Elf VP for New Ventures and negotiations, successfully establishing the company in a number of new areas such as Azerbaijan (Shak Deniz) and Trinidad & Tobago.
