Obie Djordjevic
With more than 45 years of domestic and international experience in the oil and gas industry, Obie brings deep technical expertise and proven leadership in petrophysics and reservoir evaluation. A results-driven professional, he is recognised for his strong analytical and problem-solving capabilities, combined with a disciplined approach to delivering high-quality outcomes on time. Throughout his career, Obie has demonstrated a commitment to excellence, clear communication, and team development, mentoring multidisciplinary teams and fostering collaboration across geoscience, engineering, and operations.
His technical specialisms span both conventional and unconventional reservoirs, including core acquisition and analysis optimisation, quantitative seismic interpretation, petrophysical modelling, and geomechanical analysis. He has led the application of advanced technologies such as mineralogical analysis, rock physics integration, and clustering techniques to identify reservoir “sweet spots,” improve production performance, and support complex drilling and completion strategies. Their work has consistently bridged subsurface data with practical field development, enabling better decision-making across the asset lifecycle.
Obie’s strong alignment with Geoactive stems from a shared focus on integrating advanced petrophysical workflows with cutting-edge interpretation technologies, making him an ideal partner to help clients unlock deeper subsurface insights and drive more confident, data-led decisions.
