PGS has received a Surface Prospection Clearance from the National Hydrocarbon Agency in Colombia to reprocess existing 2D lines and incorporate these lines to a MegaProject covering the Pacific Offshore.
The MegaProject will be done in partnership with Servicio Geologico Colombiano.
PGS said the new reprocessed regional Tumaco Basin dataset will provide the entry tool for exploration in Colombia’s Pacific offshore area, improving imaging of the play elements and de-risking the prospectivity potential.
The project area of interest covers most of the Tumaco offshore Basin, including the San Juan Basin. This area is characterized by the forearc basin structural style in convergent margins, related to subduction of the Nazca Plate beneath the western part of South America.
Along the South Colombia pacific margin, thick Cenozoic sedimentary sequences accumulated over blocks of transitional and oceanic crust basement that accreted between the Late Cretaceous and Early Cenozoic with a sedimentary fill of predominant from Tertiary age.
The potential petroleum system is related to source rocks of late Cretaceous and early Tertiary age, migrated to turbidites fan systems associated with the Miocene interval. Trap and seal are provided by Middle-Upper Miocene shales combined with early-Middle Miocene mud. Such a framework presents an attractive array of potential hydrocarbon-bearing traps.
“This reprocessed regional Tumaco Basin dataset will provide an entry tool for Colombia’s Pacific offshore area, improving imaging of the play elements and de-risking the prospectivity potential,” says Adriana Sola, Area Manager Latin America and Caribean at PGS.
