Milestones

TGS announces four new multi-client surveys; a 3D survey in offshore Northwest Australia, two 2D surveys offshore Madagascar and a 3D survey onshore Alberta, Canada.

The Huzzas is a 2,100 km2 3D survey that will cover the Barrow Sub-basin, offshore Northwest Australia. The data is being acquired by the M/V Geo Caspian using CGG's BroadSeisTM and BroadSourceTM technologies. Preliminary data will be available to clients from Q3 2014. Upon completion of this survey, the total TGS portfolio of 3D multi-client coverage offshore Australia will exceed 32,500 km2.

The CSM-14 and AN-14 2D surveys cover 8,847 km offshore Madagascar. CSM-14 is being acquired by the M/V Geo Arctic and AN-14 by the BGP Challenger. Data processing will be performed by TGS using its Clari-FiTM broadband processing technology and final data will be available to clients from Q4 2014.

Washout Creek, a 65 km2 3D / 3C survey, will cover the West Pembina area of Alberta, Canada. This high-density survey is designed to assist in the evaluation and development of the Cretaceous (Cardium, Manville), Jurassic (Nordegg/Rock Creek), Mississippian (Pekisko) and the Devonian (Duvernay) plays. Data processing will be performed by Arcis and final data will be available to clients from Q2 2014.

All four surveys are supported by industry funding.

In addition, TGS has signed a Letter of Award with Polarcus to utilize their vessel, the Polarcus Naila. Contingent on execution of final contractual documents, the charter will begin in April 2014 and will last for a period of six months.
