TGS announces Clari-Fi reprocessing project in Barents Sea Southeast

ASKER, NORWAY (30 April 2014) - TGS announces a 2D seismic reprocessing project in the Barents Sea Southeast in preparation for the Norwegian 23rd licensing round.  The underlying data, acquired in 2011 and 2012, is owned by the Norwegian Petroleum Directorate (NPD) and covers an area of more than 18,000 km. TGS has been applying the latest Clari-FiTM Totus processing solution to deliver seamless, fully de-ghosted broadband data.  The data will be available to holders of the original NPD data in Q3 2014.

"We are pleased to see continued strong demand from our customers for TGS' broadband processing solutions.  The Barents Sea Southeast has been nominated for inclusion in the upcoming 23rd licensing round and access to high quality 2D seismic data will be an important tool for oil companies interested in this area" stated Stein Ove Isaksen, Senior VP Eastern Hemisphere for TGS.

This project is supported by industry funding.
