About Michel Krief
Les Ulis, Île-de-France, France
Consultant Petrophysicist $125/hr
From Field Engineer (Wireline logging) to Formation Evaluation Software (Log Analysis) Specialist to (Acoustic) Petrophysicist, now Consultant Petrophysicist. Areas worked include Africa (Gabon, Algeria, ...), Europe (France, Norway, Austria, Romania, ...), Middle East (Oman, Qatar, ...), Others (New Zealand, ...). Inventor of the Biot-Gassmann-Krief model (BGK Model) with the view of using a common framework for Petrophysics (acoustic logs modeling), Rock Physics (modeling) and Geomechanics.
