Senior Engineer, Reservoir Simulation

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.
