Possible source rocks
Van Krevelen Diagram
Geochemical data suggest the presence of source rocks with type II and III kerogens. The maturity varies mostly from mature to overmature. %TOC > 1 and Hydrogen Index > 300 mgHC/gTOC

Prospectivity
• Late Cretaceous-Eocene organic rich (type II and III) potential source rocks.
• Paleocene-Miocene sandstones and conglomerates with good porosity and permeability.
• Favorable geometries for hydrocarbon accumulation, fault propagation folds, stratigraphic wedging and lateral closures against normal and inverse faults.
• CBM exploration opportunities related to Paleogene coal beds.
ANH studies. Gravimetric Anomaly Map
Future ANH Exploratory Programs
• VALLE DEL CAUCA 2D SEISMIC PROGRAM. 250 Km approximately.
• Recovery of 5160 meters of cores and electric logs: geochemical, petrographic, petrophysic and biostratigraphic analysis in the cores.
