Reinaldo J Michelena received a Ph.D. in geophysics from Stanford University and a B.S. in physics from Universidad Simón Bolívar (Venezuela). He has over 30 years of experience in research, development, and application of seismic methods to help reservoir delineation and characterization, from prototyping, programming and testing of algorithms to integrated interpretation of field data results. He worked 18 years for PDVSA-Intevep, the research and technical services affiliate of PDVSA. His last position in PDVSA before his departure in 2003 was Manager of Reservoir Delineation and Characterization. Between 2003 and 2017 he was Director of Geophysical Technologies at iResevoir, where worked in a variety of problems and geological settings where seismic data analysis results are used to constrain geological and flow simulation models, in conventional, unconventional, and naturally fractured reservoirs. In 2017, he continued his collaboration with iReservoir as Geophysical Advisor and started SeisPetro Geoconsulting, a firm specialized in the application of advanced seismic and geological modeling techniques to help in the solution of complex reservoir problems. He has collaborated with the Society of Exploration Geophysicists in a variety of roles that include Associate Editor of the journal Geophysics, Chairman of the Board of The Leading Edge, and Chairman of the SEG Translations Committee.
