Senior Engineer, Reservoir Simulation

About the role

ADNOC is seeking a Senior Engineer to develop and apply reservoir simulation models that support field development planning and production optimisation. The role involves modelling, data analysis, and uncertainty assessment to improve reservoir understanding and translate results into actionable insights for operational decisions.

Key responsibilities

• Develop and run reservoir simulation models, including basic history matching and scenario analysis.
• Support reservoir characterisation and data integration in collaboration with geoscience teams.
• Assist in fluid modelling and EOS calibration under supervision.
• Monitor model performance, identify issues, and troubleshoot simulation runs.
• Contribute to reservoir management and recovery studies such as waterflooding and EOR screening.
• Apply standard methods for reserves estimation and production forecasting.
• Support field development studies, including well performance and infill opportunities.
• Integrate production and pressure data into models to improve reliability.
• Assist in quality control of reservoir data and studies (e.g., PVT, SCAL, RCA).
• Apply basic multiphase flow concepts and reservoir engineering principles in modelling work.

Required profile

• Bachelor degree in Reservoir, Petroleum, Chemical Engineering or equivalent.
• Minimum of 72 months (6 years) of relevant experience.
• Ability to work under guidance and collaborate with multidisciplinary teams.
