Hydrocarbon potential in the Guajira Basin is associated with two different processes for hydrocarbon generation: biogenic and thermogenic. Biogenic hydrocarbons are generated from immature source rocks exposed to bacterial activity. Thermogenic hydrocarbons are produced from source rocks that have attained a sufficient depth of burial and thermal maturity level.
Source rocks in the basin may include Cretaceous, Eocene, Oligocene, and Miocene organic rich strata. The Cretaceous rocks can be equivalent to the La Luna Formation of the Maracaibo area with a kerogen type II. Source rock of Tertiary units can be type III, which give the basin its predominantly gas-prone character. Recent geochemical data indicate a late Cretaceous source rock in the deep offshore area in the western part of the basin in preserved stratigraphic sections associated with the South Caribbean deformed belt.
Figures & Tables
AAPG Memoir 108 is the first international book published on the petroleum geology and hydrocarbon potential of Colombia’s Caribbean Margin. Tis volume consists of 27 multidisciplinary papers that include a wide range of geological and geophysical topics, such as geochemistry and petroleum systems, earthquake seismology and tomography, seismic stratigraphy and sedimentology, oil and gas exploration plays, carbonate and siliciclastic petrology, basement studies, regional tectonics and structural geology, fold belt structural analyses, potential methods, and studies of deep-sea sedimentation on the Magdalena fan. This highly valuable and innovative piece of information is critical for geoscientists in the petroleum industry, research institutions, and academia. Do not miss the opportunity to learn about the extremely complex but fascinating geology of Colombia's Caribbean Margin and its important hydrocarbon potential.
