iongeo.com PROGRAM OVERVIEW The Argentine Atlantic margin is a relatively under-explored petroleum region. Covering the Colorado, Salado, San Jorge, and San Julian basins together with the Scotian-Tierra del Fuego fold and thrust belt, ArgentineSPAN provides depth-imaged data of the full crustal structure including the Moho. The program encompasses approximately 11,500 km of seismic data and is specifically designed to provide superior imaging of the area’s major basins. In conjunction with ION’s BrasilSPAN dataset, the program is designed to provide the first basin-wide, contiguous look at the petroleum systems along the South American coastline. The knowledge and expertise that has been gained from working with this data has enabled us to confidently map and interpret the 30,000 kilometers of vintage data contained in the Austral Malvinas Data Package. In addition to tying to existing seismic and well data, ArgentineSPAN images the Scotian-Tierra del Fuego fold and thrust belt, as well as the region’s full crustal structure including the Moho. This revolutionary and expansive survey also identifies new rift basins suggested by free-air gravity data, images the rifted South Atlantic marginal basins and investigates the oceanic-continental boundary position while identifying zones of seaward dipping reflectors and their continental or oceanic crust positions.
