Handbook of Borehole Acoustics and Rock Physics for Reservoir Characterization

Vimal Saxena initially worked as a Solar Energy Scientist (1980 – 1982) and served as Lecture in Physics at Sagar University in India (1983-84). He joined Oil & Natural Gas Corporation, India in 1985, and served in different Petrophysics positions until 2006. He also worked as Research Petrophysicist in ONGC-Schlumberger Joint Research Center, India (1988-93) and served Ministry of Petroleum & Natural Gas, India as Petrophysics Advisor (1997-2002). He joined Petroleum Development Oman (PDO) in 2006 and worked as Lead Petrophysicist until 2012. He also served as Exploration Team Lead (Petrophysics) in PDO. He later served Salamander Energy Singapore as Petrophysics Advisor & Head during 2012-15 and was responsible for company’s extensive exploration and development plans. He has authored or co-authored 12 research papers, and authored more than hundred interpretation reports, manuals and field development plans for ONGC, PDO and Salamander. Mr. Saxena also holds a patent for rock physics modelling. Michel Krief’s vast experience covers Africa, Europe, South America and the Middle East. He started his career with Schlumberger and served at different fields as Field Engineer (1975-83). Later he joined Copgo-Hunting to serve as Production logging engineer (1984-87). He joined CGGVeritas and worked at various positions of Petrophysicist, Acoustic Petrophysicist and FE Software specialist (1988-2002). He served PDO, Oman as Senior Acoustic Petrophysicist (2002-05). Later he served as Consulting Petrophysicist at Ipedex-Spie, Paradigm Geophysical and Beicip-Franlab (2005-07). He joined Maersk Oil & Gas to serve as Senior Petrophysicist (2007-14). In 2104 Michel Krief joined OMV Exploration & Production as Senior Petrophysicist to strengthen not only the Formation Evaluation in the assessment of carbonate and fractured reservoirs but also to contribute significantly to the interdisciplinary rock-physics activities in quantitative interpretation, fluid-substitution and poroelastic modelling within the Petroleum Engineering function. Ludmila Adam is a Senior Lecturer for the School of Environment at the University of Auckland, New Zealand. Her expertise and research interests include elastic and viscoelastic laboratory measurements and modeling of rock physics. Her research integrates laboratory and well log analysis in the context of quantitative seismic for reservoir characterization, rock-fluid interactions in CO2 sequestration, geothermal energy, fault mechanics, and volcanology. Her published research includes more than 50 peer-reviewed research articles and conference papers for SEG/EAGE/AGU.
