UK: OGA awards contracts to increase seismic database

UK’s Oil and Gas Authority (OGA) has awarded two contracts worth more than £2.5 million for 15,000 kilometers of reprocessed multi-client 2D seismic data in six areas around the UK Continental Shelf (UKCS).

OGA said on Wednesday that the contracts were awarded to Schlumberger WesternGeco and DownUnder Geosolutions (DUG), in collaboration with GeoPartners Ltd.

The areas include the Southwest Approaches, Northern Approaches and Bristol Channel, Cardigan Bay and the Celtic Sea, Morecambe Bay and East Irish Sea, the East Shetland Platform and North Western Britain which includes the Minches and the Firth of Clyde.

OGA added that this dataset will complement data from the 2016 seismic acquisition program of the East Shetland Platform and South West Britain, which began last month, and will extend the seismic coverage out to surrounding areas.

To remind, PGS and WesternGeco were awarded the contracts by the UK Government which funded the £20 million-worth ($26.6M) seismic campaign of the East Shetland Platform and South West Britain.

The reprocessed data is expected to be made available to the industry in the second quarter of 2017.

Also, OGA announced a tender for an additional six lots to reprocess a further 10,000 kilometers proprietary seismic 2D data from around the UKCS. Amongst other areas, this includes a large regional 2D seismic dataset from the Anglo-Paris Basin which will incorporate the Wessex basin where both land and marine seismic data will be reprocessed.

Nick Richardson, OGA Exploration and New Ventures Manager, said: “The combination of the Rockall and Mid-North Sea High data acquired in 2015, the two new broadband seismic data sets being acquired this summer in South West Britain and the East Shetland Platform, and the reprocessing of legacy datasets in 2016 and 2017 will form part of a consistent, modern, regional 2D seismic dataset across large, underexplored areas of the UK Continental Shelf that will be provided to the industry for a nominal fee.

“These data packages will support the evaluation of acreage to be made available in the 29th Offshore Licensing Round, which is open now, and future planned license rounds.”
