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.
