TGS Launches Advanced OBN Project in Gulf of America

In a significant move to enhance subsurface imaging in the Gulf of America, TGS, a leading global provider of energy data and intelligence, has announced the commencement of a new Multi-Client Ultra Long Offset Ocean Bottom Node (OBN) data acquisition campaign. This ambitious project, known as Amendment 4, aims to expand node coverage in TGS' Multi-Client library, adding over 1,100 square kilometers in the Mississippi Canyon, Ewing Banks, and Grand Isle South areas. The project is set to revolutionize the way oil and gas operators approach drilling in the region, offering unprecedented accuracy and detail in subsurface imaging.

The technological advancements behind this project are nothing short of groundbreaking. TGS' Gemini enhanced frequency source is at the heart of this initiative, providing lower frequency and improved signal-to-noise for ultra-long offset OBN seismic compared to conventional seismic sources. This advanced frequency source is designed to enhance input data for TGS' elastic full waveform inversion (eFWI) algorithm, resulting in more accurate subsurface imaging of the complex subsalt geology in the region. The acquisition phase of this program is scheduled for completion in Q2 2025, with final deliverables available in Q2 2026.



The potential economic and operational benefits for oil and gas operators in the Gulf of America are substantial. The improved subsurface imaging will allow operators to better understand the geology of the region, identify potential drilling targets, and optimize their drilling strategies. This can lead to increased efficiency, reduced costs, and higher success rates in drilling operations. The project is supported by industry funding, indicating a strong interest and confidence in the potential benefits it offers.

Kristian Johansen, CEO of TGS, commented on the significance of this project, stating, "This ongoing acquisition campaign underscores the critical role of OBN acquisition in providing our clients with superior seismic data. We are pleased to continue our efforts in the Gulf of America and look forward to supporting our clients' needs with our advanced data acquisition and imaging solutions."

The improved imaging can also help operators identify new opportunities for exploration and production, which can attract further investment in the region. Additionally, the project's focus on mitigating drilling risks can make the region a more attractive investment option for operators, as it can help reduce the financial and operational risks associated with drilling in complex geological environments.

In conclusion, TGS' new Multi-Client Ultra Long Offset OBN project in the Gulf of America represents a significant step forward in the field of subsurface imaging. With its advanced technological capabilities and potential economic and operational benefits, this project is poised to revolutionize the way oil and gas operators approach drilling in the region. As the industry continues to evolve, initiatives like this one will be crucial in driving innovation and sustainability in the energy sector.
