Labrador Sea 2D GeoStreamer®

Exciting deep water frontier with increasing evidence for an oil-prone source rock
Website Map for Survey Labrador Sea
Regional survey providing new and unrivaled imaging of this frontier area through improved resolution of deep structures, permitting better understanding of the relationship between basins and more reliable stratigraphic correlation.
Potential reservoirs exist throughout the section. Cretaceous synrift and postrift sediments and the Paleogene synrift sediments are common. Potential for oil prone source rocks of Cretaceous and Cenozoic age.
Long offset Geostreamer® dual-sensor technology has delivered ghost-free 2D seismic data with a high S/N ratio.
