  • Support Drilling Operations: Offer reservoir engineering expertise to support on-call asset drilling operations.
Position Accountabilities:
  • Robust Modelling: Develop and maintain technically robust reservoir simulation models to support optimal development and depletion planning.
  • Economic Assessments: Deliver recovery factor, EUR, and production forecast ranges for economic evaluations, annual production forecasts, and reserves reports.
  • Mentorship: Mentor less experienced engineers and specialists in reservoir modeling, simulation, and integration of reservoir engineering data.
  • Collaborative Integration: Collaborate with reservoir and petroleum engineers, petrophysicists, and geoscientists to ensure consistent engineering and geological interpretations.
  • Documentation Preparation: Prepare detailed documentation for new drills for internal and Joint Venture (JV) approvals.
