PGS and ION are offering a 2D data package comprising more than 25,615 km offshore Trinidad and Tobago. Six datasets will cover areas being offered in the Trinidad Open Bid Round.
They are the Deepwater Atlantic Area of 966 km of long-offset 2D; the Patao High, 2352 km of high-resolution 2D seismic data; the Western Tobago Sub-Basin of 2448 km of long-offset broadband 2D data; the Trinidad Regional Line of 5700 km of high-quality, long-offset, PSDM seismic data supplemented by 5200 km of deeply imaged reprocessing on a tight 4 km grid; and the 4900 km Darien Ridge reprocessed vintage data which is located off the east coast of Trinidad.
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.
