  1. THE GEOLOGY AND HYDROCARBON POTENTIAL ONSHORE CUBA

  2. Turquino volcanic arc Tertiary basins Outcrops of the continental margin Metamorfics Ofiolites and Cretaceous volcanic arc Geologic Map of Cuba Main tectonic elements

  3. Geologic evolution of Cuba

  4. CUBAN PETROLEUM PROVINCES AND OIL FIELDS

  5. OIL DISCOVERIES IN CUBA There had been discovered in Cuba more than 26 middle and small oil fields. Pto. ESCONDIDO VARADERO BOCA JARUCO MAJAGUILLAR STA CRUZ CRISTALES PINA BRUJO

  6. FLORIDA STRAITS ? La Habana HAVANA N Matanzas MATANZAS ? Cárdenas • LENGTH: MORE THAN 200 Km • WIDTH: MORE THAN 15 Km • DEPTH: 0.8 - 3.0 Km • AVERAGE SATURATE THICKNESS: 400 m • OIL RESOURCES IN PLACE : 30 - 50 X 10 9 BARRELS • GRAVITY: 9° - 16° API • VISCOSITY (40° C): 6000 - 550 cst.

  8. VARADERO OIL FIELD

  9. CROSS SECTION SEBORUCO OIL FIELD

  10. PINA OIL FIELD

  11. GENERALIZED STRATIGRAPHY

  12. Regional Section Western Cuba

  13. Location of Tectonic Belts

  14. SIX SOURCE ROCK LEVELS

  15. Resistivity K=200 mD SP Low perm. Neutron Gamma Ray 19.8 K=700 mD vug, karst 10.7 K=1.7 D K=30 mD K=100 mD K=60 mD RESERVOIR CHARACTERISTICS

  16. Migration-Entrapment scheme for Varadero – Cardenas Bay area

  17. THRUST BELT PETROLEUM SYSTEM

  18. HYDROCARBON SUMMARY CENTRAL CUBA

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

  20. 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.

  21. 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

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