TGS Initiates New Ultra Long Offset OBN Data Acquisition Campaign in Gulf of Mexico
Oslo-listed seismic data specialist TGS has commenced a new multi-client ultra long offset OBN data acquisition campaign in the Gulf of Mexico. The project, known as Amendment 4, aims to enhance node coverage in TGS’ multi-client library by adding over 1,100 sq km in the Mississippi Canyon, Ewing Banks, and Grand Isle South areas.
Supported by industry funding, the Amendment 4 project will leverage TGS’ Gemini enhanced frequency source to provide lower frequency and improved signal-to-noise ratio for ultra-long offset OBN seismic compared to traditional seismic sources. This advanced technology will enable more accurate subsurface imaging of the complex subsalt geology in the region.
The acquisition phase of the program is expected to be completed in the second quarter of 2025, with final deliverables becoming available in the second quarter of 2026. This initiative underscores TGS’ commitment to innovation and excellence in seismic data acquisition for the benefit of the oil and gas industry.
