Biography
Ruben D. Martinez is a Petroleum Geoscience Consultant and instructor with Reservoir Geoscience, LLC. He has been active in the seismic industry for 40 years.
Martinez was associated with Geophysical Service Inc. (GSI) as R&D Reservoir Geophysicist, Halliburton Geophysical Services (HGS) and Western Geophysical as Senior Research Geophysicist, AGI as director of Seismic Reservoir Characterization and Petroleum GeoServices (PGS) as Manager Signal Processing R&D, VP Processing R&D, VP Seismic Processing Technology, Global Chief Geophysicist I&E and Chief Geophysicist I&E NSA. His responsibilities in PGS included directing global R&D and software commercialization of processing and imaging technologies. As Chief Geophysicist, he was responsible for the supervision and quality assurance of depth imaging projects, customer liaison, the promotion of best practices and the commercialization and use of high technology.
Martinez is author and co-author of more than 70 technical papers published and/or presented at international conferences and 12 patents on seismic data acquisition, processing and imaging. He has also made professional technical presentations in more than 40 countries and has taught numerous courses and conducted seminars and workshops on seismic processing and imaging. In 2005, he was invited to present the annual Milton B. Dobrin lecture at the University of Houston. He is currently an instructor of the Continuing Education Program of the Society of Exploration
Geophysicists (SEG) and a member of the SEG Board of Directors as Director at Large. Martinez was the recipient of the 2014 Mexican Association of Exploration Geophysicists (AMGE) geophysics award for life-long achievements to geophysics. He earned a BSc in Geophysics from the Instituto Politécnico Nacional (México), MSc in Geophysics from the Colorado School of Mines and a PhD in Geosciences from the University of Texas at Dallas. He is a member of the Society of Exploration Geophysicists (SEG), European Association of Geoscientists and Engineers (EAGE), Geophysical Society of Houston (GSH), American Association of Petroleum Geologists (AAPG) and Asociación Mexicana de Geofísicos de Exploración (AMGE).
Description
Hydrocarbons are increasingly more difficult to find because reservoirs are often located in geologically complex areas. The geologic complexity has motivated a significant paradigm shift from time imaging towards the extensive use of seismic depth imaging. Depth imaging improves the definition of the structural and stratigraphic frameworks and provide a better assessment and mitigation of risk in E&P.
The goal of this course is for the participant to gain an understanding of the basic concepts and practical aspects used in building velocity models and seismic images in depth in an intuitive manner. The participant will also be exposed to depth imaging practices currently in use by geophysicists and geoscientists through the description of workflows illustrated with synthetic and field data examples. The practical aspects are emphasized throughout the course.
