Knowledge and understanding of geologic basins for hydrogeologic purposes requires an accurate 3D geological
architecture representation. For model building, surface and subsurface data integration with the interpretation
of geophysical survey and lithologic logs is needed. A methodology to reconstruct the geometric architecture of
the sedimentary basin and relationships among stratigraphic formations, as well as to define hydrostratigraphic
units, has been applied to the Campo de Cartagena Neogene formations. Data analysis included seismic reflection
profiles and gravimetric data from oil exploration, electric resistivity surveys and 491 lithologic logs. The 3D
model obtained from a close integration of stratigraphic and geophysical data was generated through a computerbased
tool. It presents a common framework and a good starting point for hydrogeologic applications. |
