Northeast AtlanticSPAN

Historically, the offshore region of the Northeast Atlantic has lacked high quality and contiguous regional seismic data.  In response to customer demand for improved understanding of the geologic evolution and basin architecture of the region, ION designed Northeast AtlanticSPAN (NEAtlanticSPAN).
 
NEAtlanticSPAN is a regional seismic and geologic program designed to address these issues with a high quality regional survey. ION worked closely with regional experts to design a survey that ties a large number of deep and deepwater wells with optimized line orientation. The program provides the industry with the only high-quality, consistent dataset for this margin and includes the longest lines ever acquired in the region. 
 
Phase 1 of NEAtlanticSPAN contains over 7,200 km of high-quality, consistent seismic data, covering three main regions along the continental margin: Ireland, Faroe/Shetland Islands, and Norway. 
 
ION managed the entire project to ensure the highest-quality survey design, acquisition and imaging technologies were applied.  The resulting data provides new insight into the architecture of the margin and increases the effectiveness of the existing data sets with improved event identification and cross-survey correlation.  
 
Key program components include:

• Deep structural imaging, including Moho, across all the basins located offshore Ireland, the Faroes and Shetland Islands, and Norway
• Definition of ocean-continent transition zone
• Specifically targeted for sub-basalt imaging
• Definition of sediment input points in deep-water Norway
• Ties to key existing 3D surveys, and important deep exploration wells
• Total planned survey length of 5,600 km in Ireland, 5,000 km in Faroes-Shetland, and 9,500 km in Norway
