| Sumario: | A kind of sedimentary basin which has engendered one of the principle aims in the science and exploration process in fundamental and applied aspects (fluids and hydrocarbons) correspond to the foreland basins and the thrust and fold belts (Lacombe, Lavé, Roure, & Vergés, 2007). This document exemplifies using the Putumayo basin, a foreland basin, located in the south of Colombia, to assess a detailed study whose main objective is determine the relation between the isostatic state and the geometry of the basin with prospective hydrocarbon areas. Utilizing the potential fields theories, the geometry of the basin was built, showing the Cenozoic and Cretaceous-Paleozoic thickness, moreover, it was delimitated the basement top throughout the basin. The model was constrained using interpreted seismic lines and formation tops in drilled wells. On the other hand, it was performed a study related to the isostatic compensation state which was based principally in the free air gravity anomaly and its correlation with the terrain gravity effect. The understanding of the isostatic state allowed to mark out the area of high pressure (sub-compensated areas) and low pressure (over-compensated areas) which was useful to show gradients and hydrocarbon migration patterns. Formerly, the structural and stratigraphic geology was understood, highlighted the fold and thrust belts systems, to favor the oil entrapment process. Finally, based on production areas and its relation with the variables and/or correlations stated previously, it was proposed new hydrocarbon exploration zones to be assessed deeply using reflection seismic technics and drilling new exploration and/or stratigraphic wells. |
