The Golfo San Jorge Basin (Spanish: Cuenca Golfo San Jorge) is a hydrocarbon-rich sedimentary basin located in eastern Patagonia, Argentina. The basin covers the entire San Jorge Gulf and an inland area west of it, having one half located in Santa Cruz Province and the other in Chubut Province. The basin has largely developed under condition of extensional tectonics, including rifting.[1]
At the center of the basin accumulated sediments reach more than 8,000 metres (26,000 ft) of thickness. Oil was first discovered in 1907 and over the years it has become the second most productive hydrocarbon basin in Argentina after Neuquén Basin.[1]
