Pozo Apartado-1Pozo Chigorodo-1
Exploration wells penetrate numerous potential sandstone reservoirs throughout the thick upper Miocene-Pliocene basin fill. Intercalated shales may be effective intraformational seals.
Trap styles include: structural-stratigraphic traps tied to known normal and reverse faults cutting the basin, and to stratigraphic pinchouts on basement in the southeast part of the basin.
Biogenic gas is a strong possibility in this thick deltaic sedimentary section.
