The Llanos Basin of Colombia is located along the eastern flank of the Andes in northern South America. The basin covers an area of approximately 194,000 km2 and it is drained toward the east and northeast by the Arauca, Meta, Casanare, and Vichada Rivers and their tributaries that join the Orinoco River. Petroleum exploration activity in this basin began with the drilling of the first well in 1944. Since then, two oil giants (Cano Limon and Castilla), three major oil fields (Rubiales, Apiay, and the Tame Complex), and more than 50 minor oilfields have been discovered, representing 1500 MBOE of cumulative production and estimated remaining reserves of more than 3050 MBOE. These hydrocarbon volumes make the Llanos Basin very prospective for future giant- to medium-size field discoveries, for which a complete understanding of the basin’s geologic evolution is necessary. Key factors in the petroleum potential of the Llanos Basin include the deposition of Cretaceous marine source rocks that were deeply buried and matured and multiple phases of orogeny that generated numerous structural and stratigraphic traps and pathways for oil migration. The main aim of this study is to provide an overview of the tectonostratigraphic evolution of the northern and central parts of the Llanos Basin, based on previously published information and our own seismic interpretations and flexural modeling of the foreland basin.
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.
