Background

About Bashar Eltahir

What drives me is transforming invisible subsurface data into impactful, field-wide strategies that boost recovery and performance. I'm a Petroleum Engineer with over 24 years in the oil and gas industry, 15 years of which spent in Subsurface activities project management and the last 9+ years focused on reservoir surveillance, production optimization, and field development planning across the Middle East, Far East, and Australia. My specialty? I have lead reservoir performance studies, designed and implemented surveillance programs (including tracer surveys, pressure monitoring, and production logging), and providing strategic input into FDPs and EOR initiatives. I am skilled in dynamic modeling, simulation, and performance forecasting with a proven track record, working in Qatar Energy LNG and Operators in MENA & APAC region in enhancing field recovery, guiding asset teams, and driving innovation in subsurface diagnostics. I’ve had the privilege of leading and contributing to some of the industry’s most innovative surveillance projects — including the first offshore co-implementation of inflow and inter-well tracers in Abu Dhabi, which I presented at ADIPEC. Using tools like Petrel, Prosper, Saphir, and Techlog, I help clients diagnose underperformance, fine-tune EOR strategies, and make confident reservoir decisions. Whether it’s calculating residual oil saturation, confirming connectivity, or continuously monitoring and assessing zonal inflow performance, I bring technical depth, analytical precision, and project leadership to every assignment. I’m excited to partner with forward-thinking teams on challenges at the intersection of technology, innovation, and reservoir optimization. Let’s connect.
