• Teacher, trainer and mentor of Petrophysicists.

Have extensive experience in both developing and delivering Petrophysical Training courses since 1980. A short summary is below:

• 1980 to 2003 - Internal (Schlumberger) log analysis training. Developed materials for computer-processed log interpretation, saturation determination, field studies and data integration. On average two to three weeks teaching per year
• 2003 to 2010 - Internal and external (Yukos, Sibneft, Rosneft, Petronas, Repsol,...) training on Russian log interpretation and field evaluation methods. Developed course for petrophysics evaluation with Techlog, taught both internally and externally (mostly North American clients).
• 2011 - Director of Curriculum for Petrophysics in Schlumberger. Designed fixed step training courses in petrophysics for data processing and acquisition staff (Wireline and LWD).
• 2012 to 2016 - Delivered at least two weeks internal (general petrophysics, and petrophysics for reservoir description) courses per year and one week external course per year.
