The latest assessments integrate petrophysical and stratigraphic analysis from 2,326 wells and utilizes over 150 core analysis reports.
This final segment follows earlier 2024 datasets covering the East Gulf Coast and broader Gulf Coast areas. The comprehensive dataset spans over 166,370 square miles and includes detailed analysis of more than 16,000 key wells, with core-calibrated petrophysical and stratigraphic interpretations, TGS reported.
The assessment incorporates data from 2,326 wells and over 150 core analysis reports to enhance geological understanding. It covers 35 stratigraphic layers, from the Anahuac Formation to the Triassic stratigraphy, providing insights into storage capacity, reservoir quality, and sealing integrity essential for carbon capture and storage (CCS) projects in the region.
Will Ashby, Executive Vice President of New Energy Solutions at TGS, stated: “This assessment underscores our commitment to delivering high-quality geological insights that help our customers make data-driven decisions. By leveraging our extensive well data library and expertise in petrophysical and stratigraphic analysis, we provide a comprehensive view of subsurface storage potential tailored to the needs of CCS stakeholders operating in the Gulf Coast region.”
In a separate development, TGS launched a new multi-client ultra-long offset ocean bottom node (OBN) data acquisition project in the Gulf of America. Named Amendment 4, the initiative will expand coverage by over 1,100 square kilometers in the Mississippi Canyon, Ewing Banks, and Grand Isle South areas.
The project employs TGS’s Gemini enhanced frequency source, which improves signal quality for ultra-long offset OBN seismic compared to standard methods. This technology supports TGS’s elastic full waveform inversion algorithm, enabling clearer imaging of complex subsalt geology in the region, the company noted.
The acquisition phase is set to conclude in the second quarter of 2025, with final deliverables expected by the second quarter of 2026. TGS CEO Kristian Johansen remarked: “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.”
TGS emphasizes its role in delivering advanced data and intelligence to the energy sector, offering solutions that enhance decision-making for oil and gas operators while supporting sustainable initiatives like CCS.
