The NSTA has purchased CGG’s NPA Satellite Mapping (NPA) database for the UKCS for publication. The UK database is composed of 983 individually interpreted satellite images, which form between a 10x and 20x temporal coverage, with 20x coverage for the majority of the North Sea. The NPA methodology uses multiple temporal snapshots in order to reduce interpretation ambiguities, account for the episodic nature of seepage and provides an interpretation of temporally repeating oil slick sites.  The release of the seeps database comes with documentation from CGG on how best to access and utilise the data and the end user is encouraged to read these in conjunction with the downloaded data. These data are being released under the NSTA’s User Licence Agreement which enables use of the data by the end user but does not permit any commercial gain to be made from having access to these data unless permission has been granted by CGG. Ownership of the data and full Intellectual Property Rights reside with CGG.
