      TGS : TGS Commences Multi-client 2D Survey in Northeast Greenland

ASKER, NORWAY (19 August 2013) - TGS has commenced expansion of a 2D
multi-client survey in Northeast Greenland.

The survey, NEG13, will enable customers to prepare for the announced
Greenland Licensing Round in 2013/2014. Due to favorable ice conditions, TGS
expects to acquire 4,200 km of 2D multi-client seismic data. This new data
will provide companies with dense data coverage over the licensing area and
will be a significant addition to TGS' already robust data library in the
area.

The seismic data is being acquired by the M/V Akademik Shatskiy supported by
the ice breaker M/V Viking Balder. A helicopter is being utilized for ice
density monitoring. Data processing will be performed by TGS and data will be
available to clients in Q1 2014.

The survey is supported by industry funding.
