PetroStrat has extensive experience in Trinidad and Tobago including wellsite monitoring via micropalaeontology and nannopalaeontology of >20 exploration and development wells offshore eastern Trinidad (with several long-duration assignments of 1 to 4 months) and routine analysis of many Cenozoic and Cretaceous well/outcrop sections from onshore Trinidad, the Gulf of Paria, Antigua, Anguilla and Cuba. Such is the structural complexity offshore eastern Trinidad (a “geologist's graveyard”) that wellsite biostratigraphy is often required to assist accurate placement of wells.
