The Caracara Sur oil field is located in the Llanos Basin, one of the largest and most prolific sedimentary regions of Colombia. The field produces 21°API oil from the Carbonera C7 formation (fm.) of Paleogene age located at a depth ranging from 4,800 to 5,500 ft below ground level. The reservoir consists of multilayered and compartmentalized sandstone packages, intercalated with shales and thin beds (1 to 5 ft) of high volatile bituminous coals and carbonaceous shales. Recent geochemical analyses have evidenced that Caracara Sur oils may have been mainly generated by a source rock of Tertiary age as suggested by the oleanane index value (>20%) and not from a Late Cretaceous source rock as it has been have been largely claimed. The geochemical analyses of carbonaceous shales and coals intercalated within the producing sandstones of the Carbonera C7 fm. exhibit an excellent source rock potential (TOC 20-55%, HI 300-400 mgHC/gTOC), containing type I/III oil-prone kerogen deposited in a marine-terrestrial environment. These organic-rich beds are considered as an excellent candidate to source the Caracara Sur oil. However, these rocks appear immature for oil generation at the field location, as indicated by Rock-Eval data (Tmax < 435°C) and measured vitrinite reflectance values (%Ro< 0.55). Multicomponent kinetic analyses rock samples were carried out to further investigate the Carbonera C7 potential as source rock. The transformation ratio and generation rate curves derived from the activation energies by applying a geologic heating rate of 3°C/Ma show the oil generation onset at 80°C with a maximum temperature (T) at 140°C and the 90% transformation ratio reached above 160°C. The present-day reservoir T at Carbonera C7 in Caracara Sur field ranges from 65 to 75°C, which supports the hypothesis that oil generation and expulsion may took place from the Carbonera C7 organic-rich beds from a nearby region or depth where they are considerably more mature, probably some 10-50 km westwards. Finally, oil-to-source rock correlation has been attempted to ensure the Carbonera C7 coals and carbonac. shales may be the Caracara Sur oil source, but it was not conclusive because correlation of mature oils to immature rock extracts is highly problematic. Further geochemical analyses and geochemical modelling are still required to better assess the origin of the Carbonera C7 oils in the Caracara Sur field. Should be this hypothesis confirmed, it would have an exciting implication for oil exploration in the Llanos Basin.
