• Integrate multidisciplinary datasets including geology, petrophysics, PVT, SCAL, pressure, and production data to guarantee physics-consistent modeling.
• Support optimization of field development plans (FDP), well positioning, and production forecasts.
• Prepare decision-ready technical outputs such as scenarios, sensitivities, and uncertainties for endorsement.
• Serve as the technical lead for simulation deliverables at governance meetings and workshops.
• Maintain and update models continuously with new data aligned with management frameworks.
• Adhere strictly to company policies, systems, processes, and procedures.

Challenges

• Ensure robust history matching across diverse data types.
• Manage uncertainties regarding STOIIP and reservoir behaviors.
• Handle integration complexities among seismic, SCAL, logs, and pressure datasets.
• Balance model readiness against project timelines.
• Produce defensible, auditable, and technically justified model outputs.
• Coordinate updates, re-runs, and scenario testing effectively.
• Align multiple stakeholders spanning field development, production engineering, geology, and upstream teams.
• Balance model complexity with practical usability.
• Support FDP optimization goals and sustainable production.
• Manage competing deliverables, workshops, committees, and support requests efficiently.

Success Criteria

• Achieve high technical standards including quality history matching and reliable predictive capabilities.
• Demonstrate deep understanding of reservoir physics, SCAL, and uncertainty workflows.
• Translate complex subsurface phenomena into clear, actionable outputs.
• Coordinate effectively across geology, petrophysics, SCAL, and production teams ensuring integration across workflows.
• Deliver clear, defensible technical presentations and ensure compliance with Integrated Reservoir Management audits.
• Oversee full model lifecycle from construction to updates and application.
• Prioritize and manage multiple requests under pressure maintaining responsiveness.
• Provide production forecasting, development scenario planning, and risk quantification.
