ASKER, NORWAY (23 June 2010) - TGS announces the commencement of a 1650 km2 high density multi-client 3D seismic survey located in the outer part of Moray Firth off the Northeast coast of Scotland.

The survey covers open as well as held acreage and is located in an area proven to be particularly prolific for hydrocarbon exploration. This has been confirmed by recent discoveries including Golden Eagle, Hobby, Pink and Blackbird.

TGS has contracted the Polarcus Nadia vessel to acquire the Moray Firth 3D survey. The Nadia will deploy 8 X 5000m of streamers for the acquisition and the project is expected to complete in late Q3-2010. The data processing will be done at TGS' imaging center in Bedford, England.

Data from the Moray Firth survey will be available for customers from Q1-2011. The Moray Firth high density multi-client 3D survey is supported by industry funding.
