  12. Caribbean Offshore Basin • PETROLEUM POTENTIAL: • Source Rock: UpperCretaceous & Oligocene age.Proven byGas production, shows and seafloor samples (oil). • Reservoir Rocks: Tertiary Sands of Cratonic (non-volcanic) origin delivered by major rivers. • Seals: Thick Upper Oligocene & Middle Miocene shaly units. • Play Types: Structures associated to oblique subduction. Accretionary prism with thrust and transform faults. • GENERAL ISSUES: • Water Depth: From shore to 2,000 meters. • Transport Facilities: There is an oil shipping port and two gas pipeline systems Agencia Nacional de Hidrocarburos

  13. Gas Fields & Shows in Wells and Piston Cores Agencia Nacional de Hidrocarburos

  14. Piston core locations Agencia Nacional de Hidrocarburos

  15. 50 Km Piston Core Data Modified from Amoco, 1998 Agencia Nacional de Hidrocarburos

  16. Petroleum System AGE FM Th RESERVOIR SEAL SOURCE ROCK LITHOLOGY Agencia Nacional de Hidrocarburos

  17. Colombia CaribbeanCretaceous Source Rocks • Oil-prone Cretaceous source rocks (2 – 14 % TOC, average 5.6%). Type II, Hydrogen Index between 39 and 1164 mg/g, abundant oil seeps in the San Jacinto Foldbelt • Oil-prone Cretaceous source rocks (2 – 15 % TOC) on Caribbean oceanic crust in Costa Rica • 700 km of the Cretaceous Caribbean Plate has underthrusted the NW Colombia accretionary prism, potentially yielding a significant hydrocarbon charge Agencia Nacional de Hidrocarburos

  18. Colombia CaribbeanOligocene Source Rocks • 2-3% TOC in the Onshore Sinu Foldbelt and Plato/San Jorge Basins (oil & gas-prone) • Live oil found in piston cores was typed like Oligocene (BP 1993 & Texaco 1999) • The seabed coring data indicates biogenic and thermogenic gas presence • Biogenic gas originated from upper Oligocene, Miocene and Pliocene source rocks (Northeast Fields) Agencia Nacional de Hidrocarburos

  19. Oligocene Reservoirs (Sinu Fold Belt) • Quartz Sand (75% Qz), fine to medium grained sandstones and some conglomeratic sandstones • Porosity between 5% to 15%, average 12%; good permeability; medium to well sorted. • Turbidites, channels and submarine fans of considerable extension. • Oligocene outcrops with thickness of 1200 feet of sandstones Agencia Nacional de Hidrocarburos

  28. Conclusions (i) • Government highly interested in promoting upstream activity • New flexible contract • Large offshore acreage with high potential • Available pipeline infrastructure with spare capacity • Proximity to the Central and North American markets. Accessibility from / to Caribbean ports Agencia Nacional de Hidrocarburos

  29. Conclusions (ii) • Oil & Gas prone basin • Proven gas producing basin, with untapped oil potential • Many positive hydrocarbon indicators • Large regional structures • Tertiary prospectivity • Optimal petroleum system • Multiclient 2D Seismic currently being acquired (3800 Km, Offshore Caribbean, rec. length 18 sec) Agencia Nacional de Hidrocarburos

  30. Conclusions (iii) • Increasing exploration activity in the area • Free geological information Agencia Nacional de Hidrocarburos
