Senior Reservoir Engineer (Studies)

About the role

QatarEnergy is looking for a Senior Reservoir Engineer (Studies) in Doha to plan, perform and support reservoir engineering studies of its operated onshore fields. The role optimizes field development plans, supports simulation models, analyses reservoir and well performance data, develops reservoir management strategies and takes part in interdisciplinary reservoir study teams and sector reviews.

Key responsibilities

• Build and run 3D multiphase black oil and compositional dynamic reservoir models, including history matching, for field development planning
• Develop and deliver optimized mid- and long-term strategic and tactical plans for the operated onshore assets
• Assess and help colleagues resolve performance and production bottlenecks
• Review resources annually and produce long-term production and injection forecasts for asset and business planning and drilling/workover schedules
• Acquire and interpret reservoir engineering data from new and replacement wells to update simulation models
• Integrate reservoir engineering inputs into new drill, replacement and workover projects, voidage management and field development
• Identify drilling opportunities and recommend reservoir layer targets, and develop detailed development and maturation plans
• Mentor and coach less experienced staff and share knowledge across the subsurface community

Required profile

• Minimum BSc in Engineering, Petroleum Engineering or Applied Sciences or equivalent
• At least 10 years of experience as a Reservoir Engineer in the oil and gas industry, with proven reservoir studies and performance optimization expertise in mature large fields
• Significant experience monitoring and managing mature oil fields under waterflood, and in fluid sampling, fluid property modelling and RCAL/SCAL studies
• Significant experience in transient well test interpretation, material balance modelling, numerical reservoir simulation (black oil and compositional), infill drilling and workover planning, and decline curve analysis using PRMS
• Experience in integrated surface production system modelling and uncertainty analysis and risk assessment
• Excellent teamwork and communication in a multicultural environment

Required skills

• Numerical reservoir simulation, history matching and field development planning
• Well test interpretation, material balance and decline curve analysis
• Industry-standard software for well inflow/outflow, surface networks, reservoir and production surveillance databases, fluid properties, material balance, economic evaluations and PRMS
• Desirable: EOR experience (CO2 WAG, miscible gas injection, chemical injection), carbonate reservoirs and operating company experience
