Gustavo is a Sr. Reservoir Engineer at BP America conducting automated workflows to evaluate unconventional assets and deploys data analytics for production optimization. He is developing full field reservoir simulation models for unconventional reservoirs using history matching in complex geologic systems containing rock matrix, hydraulic fractures, and natural fractures. Prior to his current position, he worked for Halliburton delivering Digital Oil Field intelligent strategies and operations. Gustavo has more than 20 years of experience with IOC, NOC and services companies, and he has published more than 60 technical papers on the subject of reservoir studies and DOF applications, developed more than 40 complex automated workflows that include classic reservoir and production engineering tools combined with artificial intelligence components, and has 15 patents for improving real-time model-based operations. He holds a BSc in Petroleum Engineering from the Universidad de Oriente (Venezuela), a MEng in Project Management from the U.C. Andres Bello (Venezuela), and an MSc and MPhil, both in Reservoir Engineering from Heriot-Watt University, Scotland, UK.Marko Maucec is a Petroleum Engineering Specialist, responsible for the development and implementation of advanced workflows for uncertainty quantification, assisted history matching, and production optimization of oil and gas fields. In 2015, Marko served as a Data Scientist with Blue River Analytics in Denver, CO. Formerly, he served as Principal Consultant, Chief Technical Advisor/Scientist, and Technology Research Fellow Associate at several positions in Halliburton/Landmark in the US and Malaysia. There, he was working in the areas technology development for assisted history matching and forecasting under uncertainty, integrated DOF workflows, predictive data-driven analytics, advanced geo-modeling, and subsurface imaging of conventional and unconventional assets. Previously, Marko had been a research geoscientist with Shell International E&P in Houston, TX, where he worked in quantitative reservoir management and developed methods for dynamic stochastic model inversion. Prior to entering the oil and gas industry, Marko had worked internationally in the areas of nuclear engineering and nuclear geophysics, specializing in the development of techniques for Monte Carlo simulations of nuclear radiation transport for nuclear safety and medical physics applications. Marko has published more than 80 professional technical and peer-reviewed scientific publications, has been awarded 7 patents, and is a (co)inventor on 14 pending patent applications. Marko is an active member of SPE, where he has served extensively as an invited presenter and a steering committee (co)chair at conferences, technical workshops and Forum series events. He is also currently affiliated as the technical reviewer with several professional journals. Marko holds a BSc in electrical engineering from the University of Ljubljana, a MSc in nuclear engineering from the University of Maribor, and a PhD in nuclear engineering from the University of Ljubljana (all in Slovenia).
