Senior Quantitative Geoscientist

Optimize field development | Provide integrated reservoir characterization | Improve interpretation workflows

Production optimization and development planning experience in O&G, specializing in deepwater clastic systems. Focused on adding value through robust technical analysis, opportunity identification, and innovative solutions. Routinely engage in cross-functional collaboration and independently apply advanced geophysical concepts to address key issues through clear, effective communication. Proficient in 2D / 3D seismic data integration. Adaptable and flexible to succeed in fast-paced projects. Actively facilitate team development through mentoring, knowledge sharing, and interpersonal relationship management.






ExxonMobil - Quantitative Geoscientist - Guyana Development, Liza Phase 2 2018 - 2021
Designed plans for developing 5 highly connected clastic reservoirs in a stratigraphic trap field in collaboration with drilling, completions (D&C), and reservoir engineering (RE); teams of 6-50. Established data collection strategies. Planned and executed drilling operations, geosteering, and petrophysical analysis. Coordinated seismic inversion project, managed geo and research teams, and advised peers on applications of results.

ExxonMobil - Integrated Production Geoscientist - US GOM Production, Thunderhorse Field 2015 - 2018
Mapped key reservoirs in a producing sub-salt faulted 4-way and salt flank field (GOM, Mississippi Canyon). Evaluated technical quality of operator’s depletion plans. Leveraged stratigraphy and structure skills to interpret reservoir quality and presence, often with incomplete / insufficient data. Analyzed rock properties and modeled expected seismic character. Stewarded subsalt seismic processing projects (OBN; 3D VSP), communicating key learnings, and implementing best practices.

ExxonMobil - Intern Geoscientist - West Africa Exploration, Nigeria 2014
Mapped surfaces of 2 Miocene channel complexes, analyzed AVO character, illustrated depositional scenarios and variations in reservoir quality. Evaluated well logs and identified appropriate ranges for assessment parameters.

University of South Carolina and Earth Sciences Resources Institute - Intern Geoscience Interpreter
Interpreted well logs and five 2D seismic lines as part of carbon sequestration feasibility study in the South Georgia Rift Basin, created fault framework and pillar grided model to be used in future simulation efforts.
