520			_aIncised valley and submarine canyons in Lajas Formation. Advances in the knowledge of exploratory play.The Cuyo Group reservoirs have been extensively studied in subsurface and outcrops, and their commercial exploitation s proven in traps with a conspicuous structural component. In low deformed areas and / or paleo-structures, stratigraphic traps type become relevant. In order to define new potential exploratory plays, interpretation was focused on the Middle Jurassic slope area of the Neuquén basin, and in particular on the incised valleys and submarine canyons, identified in 3D seismic, in order to characterize them as stratigraphic traps. These morphological features were recognized along a strip of more than 100 km long and 30 km wide in the central-western area of the basin in the middle and upper sections of the Lajas Formation. The depositional model, highly progradational for the Cuyo Group in the central area of the Neuquén Basin, is interrupted by cycles of relative sea level fall and rise generating the alternation of negative and positive accommodation spaces, that rthat result in the platform exposure, erosion and flooding with basinward displacement of non-marine depositional environments.The high rates of sedimentary supply could have generated unstable slopes, favorable for the generation and evolution of submarine canyons. These, in turn, during their development towards the platform break could have captured the incised valleys developed on the platform even with small relative sea level variations. Some of these interpreted eroded features and their sedimentary fill reach up to 10 km in length, 5 km in width and 200 m in thickness, being the average of about 7 km - 2.5 km - 150 m, respectively. In areas with high concentration of incisions, the stacking of different canyons and incised valleys can reach an area of about 400 km2 and a hickness of 600 m. The purely stratigraphic character of this type of entrapment (cut and fill) makes it dependent on petrophysics and lateral and vertival variation. Seal efficiency is the critical factor of this play.
