Abstract

The Andean depocenters in the northwestern border of the Neuquén basin, in the geologic province of Payenia, were characterized by means of the analyzed methods to support hydrocarbon exploration in the area. These techniques allowed studying the upper crust structures to perform oil exploration. Gravity measurements were effected and supported with GDPS (700 stations). More than 10,000 gravity values, which were provided from several campaigns over the last three decades and which constitute the database of the Geophysics and Seismological Institute “Volponi”, were also used and checked. Bouguer gravity anomalies were mapped and filtered to study the upper crust sources. We made a 3D model (by gravity inversion) integrating geological and geophysical data that emphasized the resolution of the structures placed in this area. The 3D model of the sedimentary thickness takes into account lateral and vertical density variations obtained from local wells. This model allowed identification in 2D of high and low structures studied by other authors as wellas a sub-basin, not reported up to now, found on the eastern edge of the fold and thrust belt of Malargüe that is wedged into a raised basement block belonging to the San Rafael block.
