Norwegian seismic specialist PGS has boasted with what it claims to be the world’s largest seismic spread.
The company on Thursday said its recently delivered flagship vessel Ramform Tethys made the “mega-tow” while working on its maiden project – a MultiClient 3D survey over the Aasta Hansteen area of the Norwegian Sea – with a configuration of 16 streamers, each 8.1 km long, with streamer separation of 75 m.
According to PGS, this is a recording high-density 3D seismic data from the largest amount of streamer ever towed behind a single vessel. The total spread tots up to 129.6 km of GeoStreamer®.
This exceeds the previous industry record, which was set by sister ship the Ramform Titan, in December 2015, for towing around 127 km of GeoStreamer during the first ever 18-streamer deployment in the Bay of Bengal, PGS said.
Per Arild Reksnes, EVP Operations said: “I continue to be impressed by the ability of PGS crews to utilize the Titan-class vessels, as demonstrated by Ramform Tethys and her crew on Aasta Hansteen. The performance we see from competent crews and remarkable vessels is a great asset in a challenging market.”
Ramform Tethys started acquisition in June of a new 4 400 sq. km 3D GeoStreamer® survey over the Aasta Hansteen area of the Norwegian Sea. The survey is due to be completed in August 2016, with fast track data available four months after the final shot.
