AGS said on Thursday that the Utsira multi-client ocean-bottom node (OBN) survey was completed on October 8 through a joint effort with JV partner TGS. It covered an area of approximately 1,600 square kilometers of full azimuth multi-client 3D seismic.

According to the company, the program set several production records, deployed seven vessels including two vessels fitted with AGS proprietary node handling system, 140,000 node deployments, and 3.8 million sources without any lost time incidents.

Lee Parker, AGS CEO, said: “The operational efficiency in the Utsira program demonstrates the attractiveness of OBN seismic for larger surveys to secure the highest data quality. Our OBN experience and proprietary technology enable safe and efficient acquisition and we are well-positioned for new OBN surveys in the North Sea and globally.”

Fredrik Amundsen, Europe & Russia EVP at TGS, added: “TGS is very pleased with the completion of Utsira OBN and the preliminary results from the ongoing processing. TGS remains confident that OBN will unlock further potential in Norway and will play an important part in exploration onwards.”

Following a short test program in Norway, the AGS fleet is now mobilizing for work outside the North Sea region.
