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 and risk assessment, and economics. Undertake reservoir simulation studies to attain stated objectives and translate results into operational guidelines.

Key accountabilities

Job specific accountabilities

• Coordinate and work with geoscientists on reservoir characterization and upscaling.
• Build sizable full field simulation models, history match, and use them in predictions.
• Conduct quality check and consistency of simulation model, history match scenarios with respect to geological model characteristics.
• Develop characterization of reservoir fluids and equation of state (EOS) modelling, calibration and convert simple black oil models to compositional.
• Diagnose model convergence and run-time problems.
• Coordinate with technical center in designing IOR/EOR methods (WI, immiscible GI, miscible GI, and surfactant and polymer injection) to enhance recovery and pressure maintenance methods.
• Apply different methods of reserves estimation using probabilistic and deterministic methods (Mbal, DCA and simulation models sensitivities).
• Identify required action using simulation models to maximize recovery, meet current production quotas, design, follow up, quality control and analyse reservoir studies (e.g., RCA, SCAL and PVT).
• Conduct special simulation studies for field development optimization (well spacing, infill wells, advanced wells, pilots).
• Apply 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.
• Contribute to reservoir monitoring program and data gathering with effective cost program to enable collecting necessary data to help best reservoir management and reduce uncertainties.
• Liaise with contractors conducting the study, analyse and review findings and action 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.
