Abstract
This study focused on producing maps of Palaeozoic geoforms in the subsoil of a region of the Eastern Planes basin, Colombia. The results provide novel Palaeozoic information for the study area suggesting a possible shallow marine depositional environment in the Ordovician and a slightly deeper shallow marine environment in the Cambrian. This information was obtained from the analysis of both seism stratigraphic sequences and gamma ray well logs and from the seismic interpretation of possible geological structures at depth, using a seismic cube, four 2D seismic lines and four wells. The results were complemented with the application of the seismic attributes of coherence, variance, RMS amplitude and spectral decomposition to highlight geological characteristics such as structures and lithology. The information was integrated and analyzed to generate maps of geoforms corresponding to the Middle Ordovician, Lower Ordovician and Cambrian sequences.
