Caracterización hidrogeológica y litoestratigráfica del sistema acuífero de Villa del Rosario en el predio la casona, a partir de la interpretación de métodos geofísicos de perforación y de superficie.

Abstract

In the municipality of Villa del Rosario is located the only cross border intra-mountain aquifer in Colombia, which is exploited by its inhabitants with wells for groundwater extraction. Characterizing this aquifer is important to know its capacity to store and transmit water, optimize extraction, avoid overexploitation, reduce drilling costs and contribute to the geological knowledge of the region. In order to improve the characterization and use of the hydrogeological resource in the Casona property located in the municipality of Villa del Rosario, the electrical well logs, the interpretation of an electrical tomography and a vertical electrical sounding, taken at the same point, were analyzed to obtain lithological data, porosity, shale volume, water saturation and permeability, the depth of the aquifer was identified and the basic criteria for the construction of the well that allows the use of water were presented.
