Job Purpose

Update and generate black oil and compositional simulation models for short-term and long-term field development planning. Evaluate development schemes through simulation sensitivities, uncertainty and risk assessment, and economics. Translate reservoir studies into operational guidance.

Reservoir Simulation and Characterization

• Coordinate with geoscientists on reservoir characterization and upscaling.
• Build full-field simulation models, perform history matching, and generate forecasts.
• Quality-check simulation models and history-match scenarios against geological model characteristics.
• Characterize reservoir fluids, calibrate Equation of State models, and convert black oil models to compositional models.
• Diagnose model convergence and runtime problems.
• Integrate pressure and production test results into simulation and reservoir management decisions.
• Apply multiphase flow concepts, effective permeability, and relative permeability correlations.

Field Development and Recovery Planning

• Coordinate with the technical centre on improved and enhanced oil recovery methods, including water injection, immiscible and miscible gas injection, and surfactant and polymer injection.
• Assess pressure maintenance and recovery enhancement approaches.
• Estimate reserves using probabilistic and deterministic methods, including material balance, decline curve analysis, and simulation sensitivities.
• Use simulation results to identify actions supporting recovery and production objectives.
• Design, follow up, quality-check, and analyze reservoir studies including RCA, SCAL, and PVT.
• Conduct field development optimization studies involving well spacing, infill wells, advanced wells, and pilot projects.

Monitoring, Data and Contractor Coordination

• Contribute to cost-effective reservoir monitoring and data gathering programs to reduce uncertainty.
• Liaise with contractors conducting reservoir studies, review findings, and evaluate recommended actions.
• Participate in periodic database updates and validation using monthly production and injection data.
• Review well, reservoir, and field performance information and recalibrate simulation models as required.

Supervision and Operational Management

• Plan, supervise, and coordinate assigned activities to meet functional objectives.
• Train and develop assigned staff in relevant technical skills.
• Provide budget inputs, support approved work plans, and investigate significant variances.
• Implement approved departmental policies, processes, standards, and procedures.
• Contribute to performance objectives and operational improvements, including methods aligned with relevant ISO standards.
• Provide inputs for departmental MIS and progress reports.

Health, Safety and Environment

Comply with ADNOC Onshore and ADNOC HSE requirements. Report incidents and occupational illnesses to the line supervisor. Raise unsafe practices or conditions immediately, fulfill assigned emergency responsibilities, and follow the HSE Recognition and Accountability Framework. Exercise Stop Work Authority when unsafe acts or conditions put personnel at risk.

Minimum Qualifications

Bachelor 's Degree in Reservoir Engineering, Petroleum Engineering, Chemical Engineering, or equivalent.

Experience and Technical Skills
