The Malvinas Basin 2D Seismic Reprocessing Survey comprises approximately ~11,174 km of vintage 2D field data originally acquired in 1998 with streamer lengths ranging from 4500m to 6000m.
Located in the Malvinas Basin, offshore Argentina, Searcher has commenced reprocessing through a comprehensive broadband PSTM flow. Initial results are showing considerable uplift and final data will be available in February 2018.

Due to scale, sample bias and a lack of necessity, ‘hybrid’ turbiditic–contouritic sedimentary systems are only just beginning to be recognized as a significant new breed of exploration targets. Both, what can be seen on seismic (contourite influence bedforms) and what is inferred from contourite activity (winnowed turbidites yielding high net-to-gross sands in reservoir targets), is proving to be an essential tool in identifying these exciting hydrocarbon trapping systems.
