Reinaldo J. Michelena received a B.S. (1984) in physics from Universidad Simón Bolívar (Venezuela) and a Ph.D. (1993) in geophysics from Stanford University. He has more than 30 years of experience in research, development, and application of seismic methods to help reservoir delineation and characterization, from programming and testing of algorithms to integrated interpretation of field data results. He worked for 18 years for PDVSA-Intevep, the research and technical services affiliate of PDVSA. He joined iReservoir in 2003 as Director of Geophysical Technologies, and since then he has worked on a variety of problems and geological settings where seismic data analysis results are used to constrain geological and flow simulation models. In 2017, Reinaldo became Reservoir Characterization and Geophysical Advisor of iReservoir and started SeisPetro Geosoftware, a firm dedicated to commercializing software applications developed by iReservoir. He continues his consultancy work in the areas of seismic techniques to constrain matrix and natural fracture models and flow simulation in conventional and unconventional reservoirs. He has collaborated with the Society of Exploration Geophysicists in a variety of roles including Associate Editor of the journal Geophysics, Chairman of the Board of The Leading Edge, and Chair of the SEG Translations Committee.
