LabradorSPAN is a regional seismic survey that transects the offshore Labrador Margin, NE Canada. These seismic lines were designed to intersect the region’s key exploration wells and basins and provide new insights into the volcanic margin evolution of Northern Labrador, non-volcanic evolution in Southern Labrador, and the offshore hydrocarbon prospectivity. Offshore Labrador is considered an underexplored frontier margin with only 28 wells drilled. The area has a future potential for hydrocarbon exploration and plays a role for regional petroleum system identification.
The data was acquired using acquisition parameters to image deep structures while retaining high-frequency data in the shallow sedimentary section: large seismic source, long streamer (10 km) and 18-second record length. These acquisition parameters, combined with detailed pre-stack time and depth processing, resulted in clear images to depths exceeding 40 km in places.
