Senior Engineer, Reservoir Simulation

About the Company

We 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 :

Update / Generate black oil and compositional simulation models with field development planning, short, and

long-term profiles. Conduct model sensitivities and prioritize development schemes applying best practices,

Uncertainty & Risk assessment and economics. Undertakes reservoir simulation studies to attain stated

objectives and translate results into operational guidelines.

KEY ACCOUNTABILITIES :

Job Specific Accountabilities

• Coordinates and works with Geoscientists on reservoir characterization and upscaling.
• Builds sizable Full Field simulation models, history match and use them in predictions.
• Conducts quality check and consistency of simulation model, history match scenarios with respect to
• geological model characteristics.
• Develops characterization of reservoir fluids and Equation of State (EOS) modelling, calibration and
• Convert simple black oil models to compositional. Diagnoses model convergence and run-time problems.
• Coordinates with Technical centre in designing IOR / EOR methods (WI, Immiscible GI, Miscible GI, and Surfactant and polymer injection) to enhance recovery and pressure maintenance methods.
• Applies different methods of reserves estimation using probabilistic and deterministic methods (Mbal, DCA and simulation models sensitivities).
• Identifies required action using simulation models for maximize recovery / meet current production quotas, design, follow up, QC and analyse reservoir studies e.g. RCA, SCAL and PVT.
• Conducts special simulation studies for Field Development optimization (well pacing, infill wells,
• advanced wells, Pilots)
• Applies multiphase flow in the reservoir, effective permeability concept and correlations for relative
• permeability. Integrate pressure and production test results for reservoir simulation and management decisions.
• Contributes to reservoir monitoring program and data gathering with effective cost program to enable collecting necessary data to help best reservoir management and reduce uncertainties.
• Liaises with contractors conducting the study, analyses and reviews findings and actions study recommendations. Participate in periodic update and validation of database with monthly production / injection data and descriptions to display wells, reservoir and field performance for appropriate distribution and Simulation model recalibration.
