"TGS' performance in the past two quarters, driven by strong late sales across

all regions, indicates that there has been an improvement in the underlying

fundamentals of the global market for seismic data. The combination of higher

oil price and lower cost base means that E&P companies now have more operating

cash flow that can be used for growth investments.  While we still expect some

volatility in the near-term, our counter-cyclical strategy has positioned TGS to

benefit from the improved market conditions," TGS' CEO Kristian Johansen stated.
