Labrador - Deep Basin Study 2D GeoStreamer

Perfect entry level seismic package for companies with ambitions to grow their Canada portfolio
Website Map for Survey Deep Basin Study
This unique dataset combines carefully selected high quality 2D seismic with specially designed deep basin lines that increase understanding of the basin architecture.
Large scale structural features, basement lineaments and basin development are revealed in context in this overview.
This long offset multi-sensor technology delivers ghost free 2D seismic data. Using 8100m offset and longer record length, basement features are improved and defined.
