• Define technical scopes, deliverables, and requirements for project proposals.
• Integrate seismic, well, core, and production data to develop and refine geological models, reservoir frameworks, and field architecture.
• Conduct probabilistic resource assessments in accordance with SPE-PRMS and other applicable classification systems.
• Collaborate with reservoir engineers, petrophysicists, and geophysicists to deliver integrated subsurface interpretations and maintain 3D geological models across all assets.
• Prepare and present technical documentation for internal reviews, partner meetings, Joint Management Committee meetings, and regulatory submissions.
• Mentor junior geoscientists and promote technical excellence through training and knowledge sharing.
• Ensure geological work meets governance and audit requirements and supports investment decisions through robust, evidence-based recommendations.
