A second £20million seismic data gathering campaign aimed at spurring exploration on the UK continental shelf has been completed.
The Oil and Gas Authority (OGA) said PGS and WesternGeco had collected more than 13,500 line kilometres of data.
The data will be released to the industry in the second quarter of 2017.
The OGA awarded the contracts for the seismic shoot to Norwegian firm PGS and WesternGeco, which is part of Schlumberger, earlier this year.
PGS’s Nordic Explorer vessel was due to cover the East Shetland Platform, which includes the East Orkney, East Fair Isle and Dutch Bank basins.
WesternGeco’s WG Magellan was expected to look at areas including the Celtic and Irish seas and the western English, Bristol and St George’s channels.
The surveys were part of a package of UK Government support for the troubled oil and gas sector.
A first set of seismic data was captured last year before being released at the start of 2016.
The first campaign focused on the Rockall Trough and Mid North Sea High regions.
