The Paleozoic evolution of Patagonia was the focus of controversies between its allochthonous or autochthonous origin. The arrival of plate tectonics supported new allochthonous alternatives and from an initial fixist resistance, different mobilistic hypotheses have made their way. There is currently some consensus about its allochthony, but there...

Basin modeling is a powerful tool which allows a more efficient exploration based on 3 approaches, i.e.,focusing exploration investments, reducing risks and gaining a better understanding of petroleum systems.
The former two affect the finding cost significantly; whereas from the third approach, models can be extrapolated to other scenarios and thu...
Tectonic settings characterized by west-subducting slabs typically show compressional structures formed in their accretionary prisms. These are progressively transferred to an extensional regime, as a result of the eastward roll-back of the lower plate. This transition may cause major events in a sedimentary basin: changes in accommodation, subside...
The late Palaeozoic to Triassic sedimentary record of the central Argentinean offshore was analysed through the integration of data from exploratory wells and 2D seismic lines. Our interpretations were combined with existing ones in Argentina, Uruguay, Brazil and South Africa for their analysis in the late Palaeozoic south-western Gondwana context....
Sobre la base de información sísmica y pozos de exploración de petróleo en la plataforma continental argentina entre los 35° y 41° S, fue posible documentar y caracterizar el relleno neopaleozoico sobre un área de 250.000 km2. La interpretación sismo-estratigráfica, combinada con la revisión de información bioestratigráfica costa afuera y nuevas ed...
The southwestern Gondwana basement block configuration in the central Argentinean offshore area was analyzed using gravimetric, magnetic and seismic data and existing onshore tectonic models. The resultant maps, the distribution of the Mesozoic and Cenozoic basins and Paleozoic structural features were used to validate the interpretations and to pr...
La geología precretácica de la plataforma continental argentina a la latitud de las provincias de Buenos Aires y Río Negro constituyó por mucho tiempo un espacio en blanco en las reconstrucciones del supercontinente Gondwana debido a la falta de datos sobre su composición y estructura. Sobre la base de la interpretación de información gravimétrica...
En el presente trabajo se presenta los resultados de la restauración de un corte estructural balanceado transversal al depocentro oriental de la cuenca del Colorado, y una interpretación detallada de la estratigrafía y sismo-estratigrafía de las unidades paleozoicas existentes en el subsuelo de la plataforma continental argentina a la latitud de la...
The analysis of a dense 2D seismic reflection dataset and 12 exploration wells data, allowed us to reconstruct the geological evolution of the Colorado Basin, offshore Argentina. We identified and mapped the major syn- and post-rift seismic sequences, and their boundaries such as unconformities and regional seismic markers, present on the continent...
La dorsal de Huincul es un rasgo morfo-estructural sobresaliente que prácticamente divide a la cuenca Neuquina en dos sectores, se extiende por 250 km con una orientación general E-O desde el frente orogénico andino al oeste hasta la zona de General Roca al este. Está compuesta por un tren de estructuras de orientación preferencial E-O fuertemente...
The Huincul High constitutes an outstanding E-W morpho-structural feature that splits the Neuquén Basin into two, it spans for more than 250 km from the Andean orogenic front, eastwards to the General Roca area. It is composed by a trend of E-W oriented, strongly asymmetric and south verging anticlines with a vertical throw exceeding 1.5 km. The ev...
The Volcán Auca Mahuida (VAM) Field is located in the central portion of the Neuquen
Basin; it is emplaced in the slope of a huge fisural Tertiary to Quaternary volcanic complex
and houses a recoverable reserve of 15 Mbbl of oil. The trap, which was formed as a response
to the emplacement of igneous bodies in stratigraphic units underlying the rese...
A la latitude 33° 30' S (Argentine et Chili), il y a une relation étroite entre le développement de la ceinture plissée et faillée d'Aconcague et l'évolution magmatique de la Cordillère principale. Ainsi, le taux de raccourcissement calculé à partir de coupes équilibrées est compatible dans l'espace et le temps avec l'augmentation des rapports de t...
