TGS Announces Multi-client 3D Survey Offshore Nigeria

27 Feb 2026 07:00 CET

OSLO, Norway (27 February 2026) - TGS, a leading provider of energy data and
intelligence, announces the Nigeria Laide multi-client 3D survey, acquired in
partnership with the Nigerian Upstream Petroleum Regulatory Commission (NUPRC)
and SeaSeis Geophysical Limited. The survey lies within the Outer Fold & Thrust
Belt of the eastern Niger Delta, one of Nigeria's most prolific hydrocarbon
regions and covers approximately 11,700 square kilometers.

The Laide multi-client 3D survey design is based on the GeoStreamer dual-sensor
system, long offsets, wide tow, and a triple-source configuration, delivering
modern broadband seismic data that supports full-integrity PSTM and Q-PSDM
through advanced Elastic FWI-driven velocity model building. The implementation
of this technology enables explorers to overcome the complex geological
challenges of the deepwater eastern Niger Delta, including stacked toe?thrust
structures, elongate anticlines (e.g. Bolia-Chota), inner fold-and-thrust-belt
geometries, and shale diapirs/mud volcanoes. The modern, high-fidelity 3D
seismic data provides operators with the data quality required to evaluate
prospects with greater confidence.

Kristian Johansen, CEO of TGS, commented, "Nigeria continues to play a crucial
role in the global supply of oil and gas. The expansion of our multi-client
library in Nigeria in partnership with the government through the Laide 3D
showcases our commitment to furthering hydrocarbon exploration in the region. By
utilizing industry-trusted acquisition solutions, TGS provides insights that
accelerate exploration activity and allow operators to fulfil their exploration
ambitions."

The survey is supported by industry funding.
