Principal Reservoir Engineer

Job OverviewWe are seeking an accomplished Principal Reservoir Engineer to join our exploration and development asset team in Tripoli, Libya. Reporting directly to the Subsurface Director in Doha, this is a senior-level individual contributor role suited for a technical authority who thrives on execution. In collaboration with your geoscience colleagues, you will take full ownership of day-to-day reservoir engineering tasks, asset modeling, and support technical JV governance.Key ResponsibilitiesAsset Execution: Deliver day-to-day technical reservoir deliverables, including production forecasting, decline curve analysis (DCA), and asset performance optimization.Subsurface & Commercial Integration: Collaborate directly with geoscientists to integrate reservoir parameters into static and dynamic models, ensuring all technical subsurface outcomes align with project economics and commercial asset value.Numerical Simulation: Take hands-on ownership of constructing, updating, and history-matching robust dynamic reservoir models.JV Governance & Diplomacy: Act as the technical authority during Joint Venture Technical Committee Meetings (TCMs) and Operating Committee Meetings (OCMs) to secure partner alignment.Directorate Support: Provide direct technical advisory, production forecasts, and reserve evaluations to the Subsurface Director to support strategic asset decisions.Reserves Maturation: Drive resource maturation compliance in accordance with PRMS standards, collaborating closely with G&G peers.Data Integrity & Audit: Maintain absolute oversight of all reservoir data and history-matched models to ensure complete readiness for corporate or third-party audits.Full Lifecycle Engineering: Manage the complete reservoir lifecycle, spanning fluid characterization (PVT), core analysis (SCAL), and pressure transient analysis (PTA).Technology Adoption: Identify and champion the strategic adoption of new reservoir simulation technologies and workflow improvements for the asset team.Technical Mentorship: Foster knowledge sharing and technical excellence without formal administrative reporting lines.Qualifications & RequirementsEducation: Minimum Master of Science (MSc) in Petroleum Engineering, Reservoir Engineering, or a related engineering discipline.Experience: 15+ years of hands-on, progressive experience in upstream oil & gas, with a strong background within a major or large independent operator.Regional Knowledge: Proven track record of navigating subsurface and development challenges within North Africa (prior Libya asset experience is highly advantageous).Technical Authority: Demonstrated expert-level, hands-on experience in numerical reservoir simulation, history matching, and enhanced oil recovery (EOR) projects.Commercial Literacy: Strong business and commercial acumen with demonstrated experience linking subsurface evaluations to project economics and investment decisions.Mobility: Willingness and flexibility to travel between Tripoli and asset sites as required. Software Mastery: Expert, daily proficiency in modern reservoir simulation suites (e.g., Eclipse, Navigator, Intersect, or Petrel RE).Languages: Fluency in both English and Arabic is required.
