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

Available area 12,823 km2

Drilled wells 5

Maximum thickness of the sedimentary sequence > 9842

2D seismic lines 968 km

Source rock Cretaceous-Eocene shales (kerogene type II and III)

Reservoir rock Paleogene sandstones and conglomerates

Seal rock Paleogene shales

Hydrocarbon type Oil and gas

Page 18: for  hydrocarbons

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.

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.
