Lower Cretaceous Shales – Middle Cretaceous Sandstones associated with an active generation kitchen. 2. Middle Cretaceous Shales- Upper Cretaceous Sandstones, associated with passive - active kitchens located in the northernmost and southernmost Soapaga fault regions. 3. Middle Cretaceous Shales - Upper Cretaceous Sandstones, associated with an active generation kitchen related to the Soapaga fault BURIAL MODEL Kerogene type III Kerogene type II CONCLUSIONS • The Eastern Cordillera basin is formed by thick Cretaceous Cenozoic sedimentary sequence that has been intensively folded and faulted • Gravity and seismic data support the modeling of the stratigraphic sequence and related structures at depth • Plays: Subthrust and compressional tectonics (folds/faults) • Petroleum systems: Lower cretaceous shales – Upper cretaceous sandstones National University Team Geophysical Group • • • • • • • Luís A.
