The Northern North Sea is host to many large discoveries, such as Troll, Statfjord and Brage, but recent finds such as Brasse imply that more potential fields are waiting to be discovered. The key to understanding these mature petroleum areas is to consider all the geoscience data available to reduce uncertainty and risk. This is why CGG offers integrated studies combining broadband seismic data with geology, well data and reservoir characterization to increase the understanding of petroleum plays and identify new prospects. The Northern Viking Graben study is the largest and most complete of these integrated studies that CGG has been developing in many areas of the world.
The Northern Viking Graben multi-client broadband seismic survey was acquired using CGG’s full-bandwidth BroadSeis™-BroadSource™ solution, combining a multi-layer broadband source and curved variable-depth streamer profiles with advanced imaging technology to deliver ghost-free data. The high-resolution seismic data set covers approximately 36,000 km2, straddling the border between the Norwegian and UK sectors of the North Sea. Integration of gravity data acquired with the seismic is being used to help define the basement depth. The broadband seismic data are a key component of an integrated study which will incorporate regional well correlation, prospectivity reviews, seep studies from geochemistry and satellite imagery, sedimentological and petrophysical analyses, gravity data and seismic reservoir characterization, to deliver a comprehensive geoscience package.
Broadest bandwidth, best low frequencies deliver accurate models for better decisions. Choose BroadSeis at all stages from exploration to production.
