Geophysical methods integration for deep aquifer reservoir characterization and modeling (Sidi Bouzid basin, central Tunisia)

Forward gravity modeling supported by 2D seismic reflection data over geological and geophysical methods integration, highlighted the Sidi Bouzid basin subsurface extent. It also defined its thick Tertiary complex substratum and the unknown total thickness and arrangement of its subsurface series. The used approaches provided a depth to basement modeling of the siliciclastic Tertiary complex estimating its depth and disclosing its subsurface configuration and its internal preferential water flow directions. A geophysical basement topography mapping enhancing the subsurface overview was also yielded.
