A project sponsored by the Agencia Nacional de Hidrocarburos (ANH) was carried out by the Dirección de Hidrocarburos (DTH) of the Servicio Geológico Colombiano (SGC), in order to characterize the Cretaceous units as source rock reservoirs in the Middle Magdalena Valley Basin in central Colombia. This work integrates new data from outcrops, seismic...

Organic-rich mudstones/wackestones of foraminifera and marls with a low bioturbation index are the dominant lithofacies in the Coniacian-Campanian Galembo Formation of the Middle Magdalena Valley (MMV). Sedimentological and geochemical observations are consistent with these rocks being deposited on an oxygen-deficient mixed carbonate-siliciclastic...

Organic-rich limestones of the Cretaceous “La Luna Formation” in the Middle Magdalena Basin (MMV) of Colombia is a liquid-rich unconventional petroleum play with estimated resources of 100000 million barrels in place. Rocks in this formation, however, change from facies in short distances, adding risk to the exploration of this play. In this work,...

The use of digital outcrops models plays important roles in contributing to the lack of resolution subsurface datasets. The use of lidar (Light Detection and Ranging) systems for modeling petroleum reservoir analogues in combination with sedimentological and ichnological field data improves the characterization of outcrop analogs for reservoir mode...

The ichnospecies Nummipera eocenica occurs in thick-bedded, tabular bioclastic massive sandstone of the upper Eocene San Jacinto Formation in the San Jacinto Fold Belt Basin, Colombia. Nummipera eocenica is a vertical to oblique burrow locally displaying a conical shape. The lining structure of the specimens studied consists of uniformly distribute...

The Oligocene Ciénaga de Oro Formation of the San Jacinto Fold Belt Basin of Colombia contains deposits accumulated as a result of deltaic progradation and wave-dominated shallow- marine deposits formed during transgressions in a tropical setting. Integration of ichnologic and sedimentologic datasets allows differentiation between these two deposit...

The ichnospecies Nummipera eocenica occurs in a thick-bedded bioclastic massive sandstone of the upper Eocene San Jacinto Formation in the San Jacinto Fold Belt Basin, Colombia. During the late Eocene; relative sea-level rise, a Paleocene deltaic system was flooded, leading to the establishment of open to transitional shallow-marine environments in...
