  1. PROSPECTIVITY OF ACREAGE

  2. Combined Southern Basin and South Coast Marine Area

  3. CENTRAL RANGE BLOCK

  4. CENTRAL RANGE BLOCK PROSPECTIVITY • Shallow Licence • Surface to Base late Oligocene/early Miocene (Nariva sand) • Turbidites and fans encased in calcareous clays • Existing fields– Tabaquite, Guapo, Brighton • Only shallowest thrust slice of imbricate system penetrated

  5. CENTRAL RANGE BLOCK PROSPECTIVITY • Deep Licence • Cretaceous to Oligocene • Turbidites and fans in calcareous clays • Continuation of Angostura Play Trend to onshore. • Possible early Cretaceous/late Jurassic shallow water deposits • Eocene/Early Oligocene onshore sands have similar characteristics to the hydrocarbon bearing Angostura play.

  6. CENTRAL RANGE BLOCK PROSPECTIVITY • Deep Licence • Working Cretaceous-Nariva petroleum system. • Cretaceous Deep Marine Clastics Play: very thick sandstone interbedded with shales. • Miocene Herrera Play Trends:3D imaging likely to resolve complicated structures (i.e. Corasan/Baraka). • Plio-Pleistocene Play Trend Mature play, but 3d imaging may yield new stratigraphic traps.

  7. HERRERA BLOCK

  8. HERRERA BLOCK PROSPECTIVITY • Shallow Licence • Surface to base of mid-Miocene • Turbidites, fans, deltaic and fluvial deposits • Proved potential in Southern Basin • Deep Licence • top early-Miocene and Oligocene to Cretaceous/Jurassic • Deep water deposits

  9. SOUTH WEST PENINSULA BLOCK

  10. SOUTHWEST PENINSULAPROSPECTIVITY • Shallow • Surface to base late Miocene • Pliocene and Pleistocene deltas with thick sand reservoirs • Part of the Columbus Basin gas province • Proven potential with approximately 1 billion barrels of oil production from small portion of acreage • Extension of the Pedernales Anticline, Venezuela

  11. GUAYAGUAYARE BLOCK

  12. GUAYAGUAYARE BLOCK PROSPECTIVITY • Shallow Licence • Surface to depth of 5000’ • Pleistocene and Pliocene shelfal deposits • Proven potential (production from old fields of approx. 100mmbo) • Acreage straddles Columbus Basin gas province • Probable resources: • Oil - 503 mmbo • Gas – 1155 tcf • Carambola 1 – 90 bcf gas.

  13. SHALLOW MARINE ACREAGE

  14. NORTH COAST MARINE AREA 2

  15. NORTH COAST MARINE AREA 2 History • 2D seismic - 320 Km distributed in 17 lines. • 3D seismic - 400 Km2. • Sedimentary section includes channel fill deposits and a combination of beach and barrier sands. • Producing gas reservoirs in Chaconia and Hibiscus Fields.

  16. NCO3002 SEISMIC LINE HIGH AMPLITUDE ANOMALIES 3370 3350 2550 Channel 2550 3150 NE SW

  17. NORTH COAST MARINE AREA 3

  18. NORTH COAST MARINE AREA 3 • 1980- Western Geophysical Company acquired seismic data, which showed several high amplitude anomalies. • The area is complexly faulted, therefore hydrocarbon accumulations are likely to be fault controlled. • The sedimentary section includes 20,000 ft. of Tertiary and Quaternary clastics which overlay Upper Jurassic and Lower Cretaceous low grade metamorphic rocks.

  19. BLOCK 2ab

  20. BLOCK 2ab • Continuation of the Nariva Fold and thrust belt which was successfully explored. • Prolific Angostura sands encountered in 2 wells drilled. • Prospective for oil and gas.

  21. TRINIDAD & TOBAGO DEEP ATLANTIC AREA

  22. TRINIDAD & TOBAGO DEEP ATLANTIC AREA History • Large structures mapped. • UDW province has generated and expelled hydrocarbons - viable working source system. • Piston core data confirm the presence of thermogenic gas and oil. • Geochemistry of samples similar to Trinidad Cretaceous oil source.

  23. Deep Water area - Tested but no success in shallow section (Pleistocene). However there may be significant deep Prespectivity Columbus basin play 1 Pliocene – Pleistocene deltaic listric rollover traps Ultra deep water area - abyssal plain sediments in tip thrust folds of accretionary prism Pleistocene Columbus basin play 2 Lwr Pliocene – Miocene Deep Play Chacalacca, Ibis Deep Pliocene Miocene Stratigraphic Character of Ultra Deep Province

  24. Central Range and Souterhn Basin Northern Range of Trinidad North Coast Basin Lesser Antilles Volcanic Arc Northern Basin Tobago Ridge SW NE Grenada Basin Tobago Basin Columbus Basin Post Mid-Miocene Thickening of Basin Fill Fold and thrust belt formed by partial closure of the Grenada Basin Paleogene Turbidite Complexes Cretaceous Passive Margin Underthrust basement of the Grenada Basin Inverted normal fault related to partial closure of the Tobago Basin.
