  • Ensure technical consistency, robustness, and full traceability of assumptions, methodologies, and results
  • Proactively identify value opportunities (production acceleration, recovery improvement, risk reduction)
  • Support mentoring and technical development of junior reservoir engineers
  • Support new business opportunities screening, review, and technical assurance
  • Act as a key integration pivot of critical decision making disciplines and scopes
  • Lead and/or support R&D initiatives

Requirements:

  • Strong reservoir engineering fundamentals
  • Advanced dynamic simulation capability (history matching and forecasting) using Eclipse and Intersect
  • Proven experience influencing well testing, well completion, development concepts, well phasing, and production strategies
  • Reservoir engineering studies execution, including integration of well test data into forecasts and simulations
  • Reserves and Resources classification expertise
  • Uncertainty framing and scenario-based decision support
  • Ability to translate complex technical work into clear business implications
  • Strong cross-disciplinary integration (geology, petrophysics, production, facilities)
  • Structured problem solving and analytical rigour
