TGS Announces New OBN Multi-client Survey in the Gulf of America

15 Jan 2026 07:00 CET

OSLO, Norway (15 January 2026) - TGS, a leading provider of energy data and
intelligence, is pleased to announce APEX 1, a first-of-its-kind, next-
generation multi-client long-offset Ocean Bottom Node (OBN) acquisition campaign
in the Gulf of America. Node deployment for APEX 1 commenced in December 2025,
and acquisition is expected to be completed in late Q2 2026. Early products are
expected in Q3 2026 and final data delivery Q4 2027.

APEX 1 sets a new benchmark for large-scale long offset multi-client seismic by
deploying a denser node grid than previous ultra-long offset OBN programs and by
being designed as a stand-alone exploration dataset, without reliance on
underlying streamer seismic coverage.

APEX 1 is enabled by TGS' Gemini(TM) enhanced frequency source and leverages the
TGS' deep expertise in long-offset OBN acquisition, processing, and Dynamic
Matching FWI (DM-FWI). The combination of dense node spacing, ultra-long
offsets, and advanced imaging workflows is designed to deliver a step-change in
subsurface resolution, velocity accuracy, and geological confidence for
exploration and appraisal.

This survey creates a highly flexible, future-proof exploration dataset that
supports a wide range of geological objectives. The approach opens new
opportunities for operators to deploy one of the industry's most powerful
exploration tools, not only in the Gulf of America, but also in other offshore
basins worldwide.

The project is supported by industry funding.

Kristian Johansen, CEO of TGS, commented: "TGS continues to push the boundaries
of what is possible in multi-client seismic. APEX 1 is the result of
collaboration across the entire company, from acquisition and imaging to
commercial and technology teams, and reflects our ability to listen to our
customers and respond with innovative, high-impact solutions. At a time when
efficiency, data quality, and decision confidence matter more than ever, APEX 1
demonstrates TGS' commitment to delivering unmatched value and reinforcing our
position as the leading innovator in seismic technology. We are proud of what
this project represents today and excited about the opportunities it unlocks for
our customers globally."
