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

LITHOLOGY

Agencia Nacional de Hidrocarburos


Colombia caribbean cretaceous source rocks
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


Colombia caribbean oligocene source rocks
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


Agencia nacional de hidrocarburos subdirecci n t cnica colombian hydrocarbon opportunities

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
