Geochemical Evaluation of the Middle Magdalena Basin
GEOCHEMICAL EVALUATION OF THE MIDDLE MAGDALENA BASIN GEOCHEMICAL EVALUATION OF THE MIDDLE MAGDALENA BASIN, COLOMBIA J. C. RAMON*, L. DZOU and B. GIRALDO *Colorado School of Mines, Geology Department, Golden CD 80403 Ecopetrol - Instituto Colombiano del Petróleo, A.A. 4185 Bucaramanga, Santander, Colombia e-mail: [email protected] he chemical composition of 25 crude oils from Tertiary reservoirs and 12 rock extracts from five T organic-rich Cretaceous formations in the Middle Magdalena Basin, Colombia were studied in detail by geochemical methods in order to understand their genetic relationships. The oils have been geochemically classified into four main groups based on the sulfur content, pristane/phytane, dibenzothiophene /phenanthrene, concentrations of oleanane and terpane distributions. Each group occur in different geographic locations. Oils were mainly derived from calcareous, siliciclastic and mixture of these two facies of the Upper Cretaceous La Luna Formation. Source-oil correlation is supported by sterane and terpane distributions of and carbon isotope ratios. Some oils in the eastern margin contain relatively higher concentrations of higher plant indicators than the remaining oil samples. The molecular compositions of the oils observed in this study appear to be consistent with the inferred depositional sequence of anoxic marine/pelagic carbonate facies in the north/western sector of the Middle Magdalena, while the eastern sector received a higher proportion of clastic input. This documentation supports the interpretation that the Middle Magdalena oils have been generated locally, as opposed to have migrated from the region of the Eastern Cordillera. Biomarker maturity parameters indicate that the majority of oils were generated in the early thermal maturity oil window except the Colorado-38 oil which was generated in the middle thermal maturity oil window. -

Cenozoic Foreland-Basin Evolution in the Northern Andes : Insights From
Institut für Geowissenschaften Mathematisch-Naturwissenschaftliche Fakultät Universität Potsdam Cenozoic foreland-basin evolution in the northern Andes: insights from thermochronology and basin analysis in the Eastern Cordillera, Colombia.

While widely studied in the central and southern Andes, the spatial and temporal evolution of the Cenozoic foreland basin system in the northern Andes has received considerably less attention. This is in part due to the complex geodynamic boundary conditions, such as the oblique subduction and accretion of the Caribbean plates to the already complex interaction between the Nazca and the South American plates. In the Colombian Andes, for example, a foreland basin system has been forming since ~80 Ma over an area previously affected by rift tectonics during the Mesozoic. This setting of Cenozoic contractile deformation superposed on continental crust pre-strained by extensional processes thus represents a natural, yet poorly studied experimental set-up, where the role of tectonic inheritance on the development of foreland basin systems can be evaluated. -

Asthenospheric magmas might have breached the Caribbean flat slab through a pre-existing vertical tear. Fluid migration on major faults might also explain observed low velocitiy anomalies under the Lower Magdalena Basin.

Abstract New maps of S-velocity variation for the upper and middle crust making up the northwestern most corner of South America have been developed from cross-correlation of ambient seismic noise at 52 broadband stations in the region. Over 1300 empirical Green’s functions, reconstructing the Rayleigh-wave portion of the seismic wave-field, were obtained after time- and frequency-domain normalization of the ambient noise recordings and stacking of 48 months of normalized data. -

Assessment of Continuous Oil and Gas Resources in the Middle and Upper Magdalena Basins, Colombia, 2017
National and Global Petroleum Assessment Assessment of Continuous Oil and Gas Resources in the Middle and Upper Magdalena Basins, Colombia, 2017 Using a geology-based assessment methodology, the U.S. Geological Survey estimated mean undiscovered, technically recoverable continuous resources of 0.45 billion barrels of oil and 1.0 trillion cubic feet of gas in the Middle and Upper Magdalena Basins, Colombia. Introduction –76° –74° –72° VENEZUELA The U.S. Geological Survey (USGS) completed an assessment of undiscovered, technically recoverable continuous CARIBBEAN Ccuta (unconventional) oil and gas resources in the Middle and Upper SEA CORDILLERA DE MERÍDA Magdalena Basins of Colombia (fig. 1). These basins share a 8° history of several tectonic events along the northwestern part of Bucaramanga South America that largely shaped the development of petroleum systems and potential shale-oil and shale-gas resources (Cooper and others, 1995; Acosta and others, 2007). n i Medelln Total Petroleum Systems and Assessment Units 6° For the Middle Magdalena Basin, the USGS defined the CORDILLERA ORIENTAL CORDILLERA Middle Magdalena La Luna Total Petroleum System (TPS) CENTRAL BOGOT COLOMBIA based on the presence and thermal maturation of organic- rich marine shales of the La Luna Formation. These shales NORTH are as much as 700 meters thick, and the organic matter is PACIFIC OCEAN predominantly Type II and Type IIS. Total organic carbon 4° content is as much as 18 weight percent (Rámon and others, Cali 2001; Agencia Nacional de Hidrocarburos, 2009 a, b; Veiga 0 50 100 MILES and Dzelalija, 2014). For this assessment, the USGS defined a 0 50 100 KILOMETERS Middle Magdalena La Luna Shale Oil Assessment Unit (AU) CORDILLERA CARIBBEAN and a Middle Magdalena La Luna Shale Gas AU within the OCCIDENTAL SEA TPS based on data from Spickert (2014). -
