The interpretation of horizons and faults in a seismic volume corresponds to the first step that geoscientists must take when building a static model, either to discover or develop any hydrocarbonproducing reservoir. In recent years, the implementation of secondary recovery projects has managed to support an important revitalization of hydrocarbon production in fields once considered mature. The successive advance of technology, evidenced by a significant increase in computing power, presented a strong innovation in the way of interpreting seismic data. This allows today’s seismic interpreter to feed the mapping algorithms for the generation of static models with a greater quantityand quality of seismic horizons, within the seismic vertical resolution. In this sense, the construction of a solid geomodel, composed of a continuous horizon associated with each seismic reflector located within the Comodoro Rivadavia, Yacimiento El Trebol and Mina El Carmen formations in the Golfo San Jorge basin, becomes a powerful and reliable tool for data input in the consolidation of a static model. In addition, an associated seismic attributes and spectral decomposition analysis allowed to incorporate sedimentary trends to the identified reservoirs, further integrating the available G&G information.
