Job Description

Senior Engineer, Reservoir Simulation

About the CompanyWe are the largest oil producer within the ADNOC Group, accounting for over half of ADNOC’s total oil production. As the country’s oldest oil production company, our operations date back to 1939, when a 75-year concession was signed to explore for oil and gas in Abu Dhabi. As a global industry leader in environmental sustainability, we are the first in the world to capture carbon from the iron and steel industry. Our Carbon Capture, Utilization, and Storage (CCUS) facility at Al Reyadah has the capacity to capture 800,000 tonnes of carbon dioxide (CO2) from Emirates Steel Industries (ESI) each year, for use in the Bab and Rumaitha oil fields to support Enhanced Oil Recovery (EOR). Al Reyadah is, therefore, a critical enabler of ADNOC’s 2030 sustainability goals.

JOB PURPOSE:

Support the development and application of reservoir simulation models to assist in field development planning

and production optimisation.

Perform modelling, data analysis, and uncertainty assessments under guidance to improve reservoir

understanding.

Contribute to reservoir studies and translate results into practical insights to support operational decisions.

KEY ACCOUNTABILITIES:

Job Specific:

• 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 support troubleshooting of simulation runs.
• Contribute to reservoir management and recovery studies (e.g. waterflooding, 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.
  

QUALIFICATIONS, EXPERIENCE, KNOWLEDGE & SKILLS:

Minimum Qualification

• Bachelor Degree Reservoir/Petroleum/Chemical Engineering or equivalent.
