May 9 (LNGJ) - TGS, the Norwegian-based global supplier of geoscience data for the natural gas and oil exploration and production industry, said it took advantage of improved first-quarter market conditions to report net revenues of $135 million, up 56 percent on the same period last year. “TGS's 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,” said Chief Executive Kristian Johansen. The net book value of the TGS multi-client library was $749.7M as of the end of March, it said. Recent surveys have included offshore Brazil and the Egyptian Red Sea, the US onshore Permian Basin and the Canadian Montney shale-gas formation.
