TGS Launches New Multi-Client Ultra Long Offset OBN Project in the Gulf of America

01 Apr 2025 07:34 CEST

OSLO, Norway (1 April 2025) - TGS, a leading global provider of energy data and
intelligence, announces the commencement of a new Multi-Client Ultra Long Offset
Ocean Bottom Node (OBN) data acquisition campaign in the Gulf of America. The
Amendment 4 project will 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.

Amendment 4 will feature TGS' Gemini enhanced frequency source
(https://www.tgs.com/seismic/marine-acquisition/sources/gemini), offering lower
frequency and improved signal-to-noise for ultra-long offset OBN seismic
compared to conventional seismic sources. This advanced frequency source will
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.

Kristian Johansen, CEO of TGS, commented: "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 project, supported by industry funding, is anticipated to deliver industry-
leading subsurface imaging, enabling oil and gas operators to make more informed
decisions and mitigate drilling risks.
