Southern Grand Banks 2D GeoStreamer®

Increased knowledge of exciting deep water basins with large potential
Website Map for Survey Southern Grand Banks
Large area available for true frontier exploration, in an area with scheduled land sales and a predictable fiscal regime. Discovered hydrocarbons will be close to main consumer market
Survey is on the "source rock super highway" on trend with Jeanne d'Arc and Flemish Pass Basins. Potential reservoir are expected in faulted Jurassic stratigraphy, synrift sediments, Cretaceous and Cenozoic basin margin and basin floor fans.
Long offset Geostreamer® dual-sensor technology delivering ghost free 2D seismic data with high S/N ratio
