Geological and Geophysical Services
Our staff has extensive experience with complex structural and stratigraphic fields throughout the world, including many with unconventional reservoirs such as fractured basement, tight gas, and coalbed methane. Geological and geophysical maps are fully integrated with production and engineering data to ensure reliable estimates of reserve potential. NSAI has performed field characterization and reserve assessments that range from exploration areas and early appraisal drilling to fully developed fields. Our experience covers most producing basins in the world and a wide range of sedimentary depositional environments including continental, fluvial, deltaic, marine, and deepwater. Well log correlation with integrated petrophysical, production, and seismic data is integral to all our reservoir studies.
