Recently, the incorporation of new data enabled the interpretation of new tectonic stratigraphic units of Lajas Formation, on the Río Neuquén and Lindero Atravesado fields in Neuquén basin. This discussion is driven by the integration of core data analysis, well correlation and seismic facies classification volumes generated from complex trace attributes. Use of discrete volumes improves detection of layers boundaries. We interpret twenty units of fourth-order hierarchy included in four third-order stratigraphic sequences. The tectonic origin of these units is linked to the uplift of the Río Neuquén structure during the lower Toarcian. Towards the end of the Toarcian, seismic data seems to record evidences of the arrival of sediments from the Huincul High through truncations of topsets of the underlaying sequences. Additionally, we combine seismic facies with well information in order to integrate data with different resolutions. We classify the impedance volumes into another seismic facies volume and calibrated them with electrofacies. Then, we create 3D probability volumes of occurrence for each electrofacies. The resulting volumes supported a more predictive facies propagation in the geological model. The high resolution tectono-stratigraphic interpretation enhanced reservoir location predictions. In this way, such analysis enables driving the development of the business towards areas of greater productivity.
