During 2015, a 3D seismic survey of 630 km2 was recorded in Lindero Atravesado field in Neuquén basin. The objective of this seismic was to characterize the unconventional reservoirs of Grupo Cuyo, that had begun to develop rapidly since 2012. The seismic was designed with the objective of achieving a good structural and stratigraphic image. Likewise, the design contemplated having angles large enough to be able to characterize these deep reservoirs through seismic inversions and special attributes. This paper present, a description of the workflow performed and the results obtained for the Deterministic and Geostatistical Simultaneous Seismic Inversion made with this new seismic data. Both inversions showed very good correlation and adjustment with well data, and validate how it is possible from the seismic data to characterize the unconventional reservoirs of Lajas Fm at a depth of more than 4000 mbgl.
