RANGEL, Antonio; GONZALEZ, Santiago  and  POSADA, Claudia. APPLICATION OF PRODUCTION GEOCHEMISTRY FOR NEW EXPLORATION OF THE CICUCO-BOQUETE-VIOLO AREA: COLOMBIA. C.T.F Cienc. Tecnol. Futuro [online]. 2004, vol.2, n.5, pp.69-82. ISSN 0122-5383.

This study involves the oil geochemical evaluation of twenty-eight (28) wells in the Cicuco-Boquete area with the purpose to establish reservoir continuity, to infer pathways of hydrocarbon migration and opportunities for new explorations in the area. As for reservoir connectivity, the Momposina and Boquilla fields are not connected among themselves or to the Cicuco-Boquete fields and the Cicuco-Boquete oils seem constitute various subgroups, indicating stratigraphic and/or structural discontinuities inside their reservoirs. The Ciénaga de Oro Formation is the main source rock in the area and their extracts show correlation with crude oils from the Cicuco-Boquete fields. As for the pathway of migration related to the Ciénaga de Oro Formation, the generation zone can be divided in at least three areas, related to the two main faulting tendencies. These are four different migration routes related to the accumulations of: 1) Cicuco-Boquete; 2) Momposina-1; 3) Ayombe-1 and Guepajé-1; and, 4) Apure-1 and Apure-2X. Regarding new exploration opportunities, it is suggested that structures located along the migration route be evaluated, especially those structures along the migration pathway.

Keywords : reservoir continuity; migration pathways; oil generation.
