The Oil and Gas Authority has today published the results of the £20 million seismic programme to promote exploration activity in under-explored areas of the North Sea.

This data will support the forthcoming 31st Offshore Licensing Round which will open in Spring 2018.

The new marine 2D surveys, acquired during Summer 2016, cover the East Shetland Platform and South West Britain areas, with reprocessed datasets stretching along the English Channel and up the western areas of the UK as far as the Hebrides.

Together with data from the 2015 seismic programme, this provides a regional exploration dataset for almost all of the UK’s under-explored offshore shelf, in regions where no substantial activity has occurred in decades.

This dataset is now available to industry and academia, and contains close to 19,000 km of newly acquired broadband seismic data, new gravity and magnetic surveys, approximately 23,000 km of reprocessed legacy seismic data, a rejuvenated set of digital well data, in addition to various supplementary reports.

The OGA has also released a set of regional studies on the East Shetland Platform and SW Approaches Basin and a comprehensive set of regional maps across the Southern North Sea to supplement maps published earlier this year for the Central North Sea and Moray Firth. An updated UKCS well tops database is also available with the aim of providing these data in a more readily accessible format.

The East Shetland Platform and SW Approaches studies were funded by the OGA through the 21st Century Exploration Roadmap (21CXRM) initiative and the contract for a second phase of studies in these areas, jointly funded by the OGA and an industry participant group, was recently awarded to APT.

Jo Bagguley, OGA principal regional geologist said: “The seismic acquisition programme is a vital part of the OGA’s plan to help revitalise exploration with up to £40 million already spent to provide modern coverage of nearly all underexplored regions of the UKCS. This new data will provide valuable insight to companies identifying new plays and prospects ahead of the 31st Offshore Licensing Round in 2018.

“There is a lot to play for with up to 10 to 20 billion barrels of oil still remaining. The challenge is now for industry to increase the level and quality of exploration drilling across the basin and work together with the OGA in maximising economic recovery.”

Key data packages can be downloaded for free, with complete data packages (including field data) available to order on media from www.UKOilandGasData.com.

The larger data packages will be available on digital media only, for which a nominal charge will be made to recover delivery costs.
