Offshore Uruguay came into the focus of oil majors and independents with 2012's highly successful Uruguay Ronda II. BP was successful in acquiring 3 blocks in this round with the identification of various play types along the Uruguayan margin. One of these plays involves a Cretaceous deep water depositional system with potential for sand pinch-outs along the slope and basin floor. A similar type play has enjoyed much success in the Equatorial Atlantic Margin. This talk will address the key tectono-stratigraphic drivers of the play, including deep crustal controls, hinterland tectonics, sediment input points and stratigraphic architecture.
