• Perform reservoir modelling and dynamic simulations, history matching/calibration, and subsurface uncertainty analysis.
• Use fit-for-purpose integrated predictive tools and models to evaluate incremental well & development opportunities, and to assess production forecasts and reserves.
• Develop, build and adapt reservoir models, working with geoscience, petrophysical and petrotechnical disciplines.
• Prepare and document production forecasts for producing assets for short-term and life-of-field forecasting, working with Production teams to ensure appropriate Well and Reservoir management.
• Initiate technical and business cases for incremental projects to optimize production and maximize economic recovery.
• Evaluate further development strategies and incremental investment projects to mature contingent and prospective resources.
• Provide technical support for well planning and completions design and execution, including testing and sampling operations as required.
• Perform reserves and resources estimates, classification, and documentation for reserve reporting internally.
• Act as a technical leader on projects when required, coordinating cross-discipline activities.
