Trinidad’s Geologic Story

The Neogene-Recent deepwater Trinidadian basins were formed during the arrival of the Caribbean Plate by a complex interaction with the pre-existing Atlantic Plate. This west-to-east collision resulted in the subduction of the Atlantic Plate by the overriding Caribbean Plate and an oblique collision with the northern South American passive margin. This advancement of the Caribbean was coeval with the Miocene initiation of the Orinoco Delta in the eastern Venezuela-Trinidad region and was responsible for the deposition of main reservoir intervals in the basin.

In the deep water, sediment loading from the delta-generated shale walls and diapirs in the Columbus Basin while strike-slip faulting in the Tobago Trough to the north, formed basement highs, such as the Patao KK High. Both basin settings offer significant structural and stratigraphic trap potential.

Shales from the Late Cretaceous Naparima Hill and Gautier formations constitute the main source rock in this region, equivalent to the Canje Formation offshore Guyana. Additionally, the Early Miocene oil-prone Cipero formation source rock has potential for maturity where burial depth is sufficient, in the deepwater Columbus Basin.
