Presentation in Spanish.
A campaign of geochemical exploration and heat flow was carried out in the Colombia basin by the DIMAR. The campaign included the interpretation of geophysical data for the identification of optimal sampling sites, followed by the acquisition of 45 samples, their processing and geochemical análisis, some on board and others of samples selected to a geochemical laboratory on the ground for the analysis of biomarkers, diamontoids and carbon isotopes. The remaining central material was labeled and delivered for DIMAR for archival purposes. In addition, a heat flow campaign was completed to better understand the geothermal regime of the region and its potential for hydrocarbon formation.
The interpretation of the results of the analyses shows negligible amounts of thermogenic compounds (saturated and aromatic hydrocarbons) that increase south and southwest along the abyssal areas. Tentatively, given very low concentrations, biomarkers and diamontoids suggest that a source rock with a kerogen type II and type II/III may be the source of these hydrocarbons whose maturity stage does not exceed the peak of the oil window.
