Specialist Profile

Short CV Cécile is a structural geologist and borehole log interpretation specialist who aims to unravel characteristics of fracture systems which conduct fluid flow in the Earth's crust. Her structural and geomechanical analyses in geothermal, hydrocarbon and active fault systems improve resource management and understanding of tectonics. She complements borehole data with outcrop, completion well test data and 3D-modeling studies and thrives in cross-disciplinary projects. Cécile has been involved in most borehole image log interpretations in New Zealand geothermal fields since the first deployment of ALT high temperature ABI tool in 2009. She has also interpreted borehole data in three scientific drilling programs: Iceland Deep Drilling Program (Iceland, 2009); Deep Fault Drilling Program (Alpine Fault, South Island of New Zealand, 2014); and IODP Exp. 376 Brothers Arc Flux (Kermadec arc offshore New Zealand, 2018).
