• Identified and evaluated new prospective reservoir zones that effectively doubled field resource estimates following successful drilling campaigns
• Directed geological assessments and regional evaluations for frontier acreage, farm-in opportunities, and heavy oil developments
• Integrated seismic, petrophysical, production, and engineering data to support field appraisal and development studies
• Coordinated multidisciplinary teams across subsurface and operational projects, overseeing technical delivery, recruitment, mentoring, and capability development
• Supported stakeholder engagements with regulators, technical partners, and government agencies to advance development approvals and project alignment
• Established integrated subsurface workflows and best-practice approaches for technical evaluations and well planning activities

Senior Earth Scientist / Team Lead at Chevron Corporation (2007-05 – 2021-08)

• Technical project leadership in the delivery of 2 × ~30-well infill drilling campaigns in mature brownfield assets
• Increased production by >10% in a ~50,000 bopd field through integrated subsurface evaluation and optimized well placement
• Contributed to strategic evaluation of a ~4.3 TCF gas development project
• Led integrated geological and reservoir characterization studies supporting exploration, appraisal, field development, and production optimisation across operated offshore and onshore assets
• Developed and updated 3D geological and reservoir models in Petrel by integrating seismic interpretation, petrophysical analysis, biostratigraphy, core data, and production history
• Supported field development planning and depletion strategies for five producing assets, contributing to improved recovery and extension of field life by up to 10 years
• Led workover optimisation and EOR evaluation initiatives, significantly improving recovery performance in mature reservoirs
• Planned and supported well operations, including well proposals, geotechnical documentation, data acquisition planning, daily operational support, and post-well evaluations
• Generated and maintained subsurface interpretations including structural contour maps, thickness maps, cross-sections, and reservoir framework models
• Identified and matured exploration and appraisal opportunities to drill-ready status through seismic interpretation, attribute analysis, inversion studies, and volumetric evaluations
• Integrated production and engineering data into reservoir evaluations and forecasting activities to support production targets and development decisions
• Participated in technical peer reviews, assurance reviews, and functional evaluations within subsurface project workflows
• Conducted regional evaluations and new venture studies supporting portfolio optimisation, investment decisions, and asset screening activities
• Represented subsurface teams during multidisciplinary technical engagements and collaborative partner discussions
• Mentored junior and mid-level geoscientists and engineers, strengthening technical capability and succession development across asset teams
• Ensured compliance with subsurface data management standards, technical governance processes, and HSE requirements

Exploration Geophysicist at TotalEnergies (formerly Total Petroleum Company) (2002-05 – 2007-04)

• Conducted regional and field-scale seismic interpretation to support exploration prospect generation, petroleum systems analysis, and development evaluations
• Developed structural and depositional models supporting field appraisal, exploration ranking, and drilling decisions
• Evaluated ultra-deepwater opportunities within the South Atlantic Margin for bid rounds and portfolio expansion activities
• Performed depositional fairway analysis, palaeo-shelf mapping, and basin evaluations supporting regional exploration strategies
• Generated prospect maps, volumetric estimates, and integrated geological interpretations for technical evaluations and management presentations
• Assessed operated and competitor assets for joint exploration opportunities, strategic partnerships, and new venture screening
• Supported multidisciplinary exploration teams with technical documentation, interpretation updates, and data integration workflows

Environmental Analyst at Severn Trent Ltd (2000-09 – 2001-08)
