THRUST BELT PETROLEUM SYSTEM


HYDROCARBON SUMMARY CENTRAL CUBA


CONCLUSIONS

STRATIGRAPHIC SECTION OF CUBAN BASINS INCLUDES A THICK MARINE JURASIC – CRETACEOUS SEDIMENT DEPOSITED WITHIN THE PROLIFIC GULF OF MEXICO PETROLEUM MEGAPROVINCE


CONCLUSIONS

  • CUBAN FOLDED - THRUSTED BELT CONTAINS HIGH QUALITY SOURCE ROCKS OF JURASSIC AND CRETACEOUS AGE WITH REGIONAL DISTRIBUTION AND A FAVOURABLE TIMING OF HYDROCARBON GENERATION AND ENTRAPMENT.


CONCLUSIONS

  • WIDE RANGE OF OIL QUALITIES IN CUBA.

    • LIGHTER OILS IN CENTRAL STRIP OF THE ISLAND, IN NORTHWESTERN PART OF CUBA AND IN DEPTH.

      CUBAN HEAVY OILS ARE MAINLY UNMATURES OILS


CONCLUSIONS

  • CUBA HAS AN EXCELLENT HYDROCARBON POTENTIAL. THE DISCOVERY OF LARGE OIL FIELDS IS POSSIBLE.
