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.

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 converts 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 to 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. Integrates 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. Participates 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.

Minimum Qualification

• Bachelor’s degree in Reservoir/Petroleum/Chemical Engineering or equivalent.

Minimum Experience & Knowledge & Skills

• 6-8 years of experience in reservoir engineering including oil and gas fields’ development management and Full Field simulation studies (use software models).
• Reservoir and Production Operations Knowledge.
• Analytical Reservoir characterization (Material Balance) knowledge.
• Numerical reservoir simulation (Eclipse, Intersect).
• Pressure Transient Analysis and Well Performance knowledge, PVT Modelling.
