  6. Regional Setting Coastal Belt Basement Depth Tambaredjo/Calcutta oil fields > 1 billion barrels in place

  7. Onshore Play Cartoon Coastal Plain Coastal Marine Tidal Flats

  8. Source Rock Distribution Turonian/ Cenomanian Petroleum System 34 Tambaredjo/Calcutta oil fields > 1 billion barrels in place

  9. Turonian/Cenomanian System (1) • Source rock present in all wells off deep shelf • Thickness between 120 and 550 meters • Type II organic matter (oil-prone) • TOC 4-7%; 14% in the DSDP wells • Oil expulsion started in Eocene times • Source rock currently mature for oil

  10. Turonian/Cenomanian System (2) • Oil gravity decreases towards the kitchen area • Migration routes exceed 100 km • Tambaredjo and Calcutta crude sourced from Cretaceous marine organic matter • World-classsource rock equivalent to Naparima Hill (Trinidad) and La Luna (Venezuela)

  11. Events Chart Turonian/Cenomanian Petroleum System Time Habitat Post-rift thermal subsidence in transform passive margin setting

  16. Tambaredjo/Calcutta Fields • Stratigraphic traps (up-dip pinch-outs) • No structural trapping • Best trapping potential in tidal flat setting • Tidal channels not connected to the coastal plain possess the best trapping chance when sealed by high-stand clays • Palaeo-estuaries fixed from PC to MI • Westward drift relatively young

  17. Onshore Play Concept Explains: • Presence of oil in Tambaredjo and Calcutta > Good seal in clay-dominated tidal flat setting • Absence of hydrocarbons in wells drilled close to present-day estuaries, or in a palaeo-estuary (e.g. Wageningen area) > Lack of seal

  19. Onshore Prospectivity Access to mature Turonian-Cenomanian source rock Tambaredjo/Calcutta oil fields > 1 billion barrels in place

  20. Onshore Prospectivity Material Balance Estimate Mature Cenomanian/Turonian Source Rock Input parameters: Gross source rock thickness 100-300m, N/G 10-50%, TOC 7-9%, HI 300-400 grHC/kgTOC, migration loss 90-100% > 4 Billion Barrels Total Charge Expectation

  21. Play Map

  22. Onshore Prospectivity Opportunity Ranking 2.7 Billion Barrels Total Oil in Place Expectation Estimate based on prospective area size, calibrated with known Tambaredjo/Calcutta volumes

  23. Conclusions • Good oil potential onshore outside existing fields • Low reservoir and charge risks • High seal and trap risks Best trapping possibilities away from present-day estuaries (corrected for present-day westward drift) • Expectation: 2 - 4 billion barrels in place
