Pascal Desegaulx




Pascal Desegaulx, Manager, Geophysics Operations & Technologies


After completing his training in topographical engineering at the Ecole Spéciale des Travaux Publics, du Bâtiment et de l’Industrie (ESTP), Pascal Desegaulx studied geodynamics at the Université Paris-Sud and later at the IFP School. He has accumulated 28 years of experience at Total in the field of exploration and deposits.   


From 1987 to 1992 he spent the initial part of his career conducting research, first at the IFP School and subsequently at Total. He then joined Total’s seismic data processing unit, where he was able to draw on the department’s research activities to tackle the operational issues posed by imaging and 2D-3D data acquisition. His next position was heading the seismic data processing team in Kazakhstan.


From 1996 to 2002 Pascal worked as a seismic data interpreter on a wide range of projects, in locations including Angola, Venezuela, Indonesia, the Middle East and Malaysia.


In 2004 he joined the geophysics department in Pau, where he headed the seismic reservoir characterization group. He later became director of geophysics in the Deposits Division. After ten years in that role he was given the task of restructuring and supervising the development team for Total’s in-house geoscience software. He simultaneously served as director of geophysics for Total Nigeria.


In his current position as manager of geophysics operations and technologies, Pascal oversees the engineers supporting the exploration and deposits operations.
