TGS Launches Amendment West-1 Ultra Long Offset OBN Survey, Advancing Multi-client Coverage in the Western Gulf of America
TGS Launches Amendment West-1 Ultra Long Offset OBN Survey, Advancing Multi-client Coverage in the Western Gulf of America
OSLO, Norway (29 September 2025) - TGS, a global leader in 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 West-1 survey is TGS' second campaign expanding multi-client node
coverage in the Paleogene West play, adding more than 5,400 square kilometers
within the East Breaks protraction area.
Amendment West-1 will feature TGS' Gemini(TM) enhanced frequency source and TGS'
ZXPLRe(TM) nodes. The Gemini source has been engineered to generate increased low-
frequency energy for deep penetration and Full Waveform Inversion (FWI), while
preserving high-frequency content necessary for conventional processing and
imaging workflows.
The Amendment West-1 dataset, to be processed by TGS' Imaging experts, will
improve subsurface clarity of the emerging Paleogene west play potential in the
East Breaks area. This area is projected to be highly competitive in upcoming
lease rounds, especially for operators focused on the Paleogene play, which has
gained momentum through recent production-related technological breakthroughs.
Leveraging TGS' Elastic Full-Waveform Inversion (E-FWI) and Reverse Time
Migration (RTM) imaging technologies, and integrating TGS' Crystal C wide
azimuth streamer data, the new survey is designed to deliver best-in-class
seismic data to support both exploration and development activities.
Amendment West-1 node deployment commenced mid-September and data acquisition is
expected to complete in mid-March 2026, with delivery of initial products
scheduled for Q2 2026. The project is supported by industry funding and was not
included in the booked position disclosed in TGS' Q2 2025 presentation.
Kristian Johansen, CEO of TGS, commented: "TGS remains committed to supporting
the energy industry with the highest quality seismic acquisition and imaging
solutions. With the Amendment West-1 OBN survey we expand on our success of
providing multi-client OBN programs over existing wide azimuth streamer data in
the Gulf of America, and this survey is playing a pivotal role in facilitating
Paleogene exploration targets. Our recent processing advances have attracted
considerable industry attention, highlighting TGS' top tier advanced imaging
capabilities. Through a combination of advanced seismic source and imaging
technologies and our leading edge OBN acquisition capabilities, we are confident
this project will provide tremendous value to our customers."
