Valles incisos en el paleoceno de la Cuenca del Golfo San Jorge
Feinstein, María Alejandra Torres, Ramón Lisandro
Valles incisos en el paleoceno de la Cuenca del Golfo San Jorge - 2018 - 17 p. ; 713-730
From the interpretation of the 3D seismic record in the study area Cerro Cuadrado, of the northern region of Santa Cruz province, in the folded belt area of the San Jorge Gulf Basin, the existence of paleovalleys with sedimentary fill corresponding to Paleogene is postulated. A basal reflector was interpreted as reference surface to the mentioned features. The horizontalization of the 3D seismic volume from this horizon allows to interpret the erosive surfaces and the morphology of the drainage network, both in the seismic sections and in the horizon time slices.Although it is necessary to continue studying to fully understand the controls that generated the incision and the prospectivity of them, it can be said that its generation may be related to upstream controls. The main characteristics of the paleovalleys, such as geometry, orientation, dimensions and their relevance as a possible oil evaluation opportunity for this sector of the Gulf of San Jorge Basin are described. Incised valleys form stratigraphic plays in different basins around the world, so they should be considered as an attractive opportunity for oil evaluation
