Oslo – October 11, 2026 -- TGS and Chevron Corporation (NYSE: CVX) have agreed to jointly invest in research and development of next-generation seismic imaging technology, the companies announced.

Partners target eFWI and machine learning workflows

The R&D effort covers key technical domains including Elastic Full Waveform Inversion (eFWI) and machine learning–driven workflows. The work will draw on TGS' Imaging AnyWare platform and Chevron's proprietary algorithms.

Financial terms, investment size and project timelines were not disclosed in the announcement.

TGS CEO frames deal as step toward strategic imaging partnership

TGS CEO Kristian Johansen said the collaboration reflects the company's ambition to become a "true strategic imaging partner." He said combining TGS' platform, talent and scale with Chevron's geoscience expertise creates long-term value for both organizations.

Oslo – October 11, 2026 -- TGS has won a streamer acquisition contract in the Mediterranean that extends its streamer backlog well into the first quarter of 2027. A Ramform Titan-class vessel is scheduled to mobilize in the fourth quarter of 2026, and the survey is expected to run approximately 110 days.

TGS deploys Ramform Titan-class vessel for the Mediterranean survey

The award covers a single survey with a duration of about 110 days. The source does not disclose the client, the contract value or the survey area within the Mediterranean.

Contract lengthens TGS streamer backlog into early 2027

CEO Kristian Johansen said the award extends the company's streamer acquisition backlog well into the first quarter of 2027. He described it as a reflection of continued demand for high-quality seismic data supporting offshore exploration activity.

Oslo – October 11, 2026 -- TGS has been awarded data brokerage, marketing and licensing rights by the Petroleum Authority of Brunei Darussalam (PA) for subsurface data over an offshore Brunei block.

Award covers 3D seismic, well data and technical reports for one offshore block

The package includes 3D seismic data, well information and associated technical reports across the block. E&P companies can use the material to evaluate the acreage and reduce subsurface uncertainty before they take part in the block licensing process.

Brunei's PA targets international upstream investment

The project supports the Petroleum Authority's broader objective of attracting international investment into Brunei Darussalam's upstream sector. TGS says the award complements its existing multi-client footprint across the Asia Pacific region.

Oslo – October 11, 2026 -- TGS has secured a one-month extension to the largest seismic streamer acquisition contract offshore Indonesia, with the extension scheduled to start in August.

Extension keeps Ramform Sovereign working under the Indonesian contract

The extension covers the Ramform Sovereign vessel, which acquires data using TGS's GeoStreamer technology. TGS did not disclose the contract value, the client's identity, the survey area or the vessel's remaining backlog.

TGS CEO says extension improves revenue visibility

CEO Kristian Johansen said the extension reflects the client's continued confidence in the Ramform Sovereign and GeoStreamer. He added that the project strengthens revenue visibility while TGS delivers high-quality seismic data with industry-leading acquisition efficiency.

The extension is short, at one month. Its financial impact is therefore likely to be limited, and TGS has not published figures.

Oslo – October 11, 2026 -- Only 2.1 GW of offshore wind capacity has reached final investment decision (FID) so far in 2026, while more than 12 GW is expected to enter operation this year, according to TGS | 4C's latest quarterly Global Market Overview.

TGS | 4C forecasts 5.6 GW will reach FID by year-end. That would make 2026 the second-lowest year for offshore wind investment decisions since 2020.

Consent awards of 22.2 GW point to the second-highest year on record

Final consents are advancing strongly, with 22.2 GW forecast to be awarded in 2026. Early-phase development assets and projects under construction are both progressing, but developers remain cautious about committing capital to the next generation of projects.

Global offshore wind capacity stands at around 92.7 GW in operation, with a further 41.2 GW under construction and 7.1 GW at FID.

Oslo – October 11, 2026 -- TGS | 4C has launched an Onshore Wind Intelligence Platform that extends its project-level market data from offshore wind to the onshore sector, with an initial release covering European markets.

Platform links onshore projects to the organisations behind them

The platform combines project, supplier and market intelligence in a single resource. It targets developers, suppliers, analysts, financiers, policymakers and strategy teams. By connecting project activity with the organisations involved, it gives users a view of market movement, supply-chain relationships and emerging commercial opportunities.

Users can assess project pipelines and track developments to inform strategic and commercial decisions. The platform pairs detailed, up-to-date databases with map-based and GIS solutions and insights.

OSLO – October 11, 2026 -- TGS has launched a 514-square-kilometer 3D PSDM Multi-Parameter-FWI reprocessing project over PETRONAS' 2025 Megah discovery in Block SB-3K, offshore Sabah, Malaysia, with final products due in April 2027.

TGS applies elastic full waveform inversion to its 2017 Sabah dataset

The project applies TGS' Elastic Multi-Parameter Full Waveform Inversion and depth imaging technologies to the company's own legacy Geostreamer Sabah multi-client 3D Phase 2 dataset, acquired in 2017. TGS aims to deliver an improved dataset built on a high-resolution velocity model and diffraction imaging across the Megah Field.

Processing began in July 2026 and runs to April 2027

Work started in July 2026. Final products are scheduled for April 2027, roughly nine months after the project began.

Oslo – October 11, 2026 -- TGS will release its third-quarter 2026 results at approximately 07:00 a.m. CEST on 22 October, with management presenting the figures two hours later in a live webcast.

CEO and CFO to present Q3 figures at 09:00 a.m. CEST

CEO Kristian Johansen and CFO Sven Børre Larsen will lead the 09:00 a.m. CEST presentation on 22 October. The session will be webcast live, and viewers can register through a link on the front page of the company's website.

Earnings release and slides to be published on two platforms

The Q3 2026 earnings release and the accompanying presentation will be available on TGS's corporate website and on the NewsWeb disclosure platform.

TGS describes itself as a global provider of energy data and intelligence. The announcement did not include preliminary financial figures or guidance for the quarter.

Investor inquiries go to Bård Stenberg, VP IR & Business Intelligence.

Oslo – October 11, 2026 -- TGS expects multi-client investment of about USD 63 million in Q3 2026, down from USD 85.9 million in Q3 2025, according to its preliminary financial review.

OBN crew count of 2.2 beats expectations

The normalized Ocean Bottom Node (OBN) crew count for the third quarter was 2.2, slightly above company expectations. TGS completed two OBN contracts during the period: one in the Gulf of America for a client with which it has a long-term capacity agreement, and a node-on-a-rope contract in Europe.

North Sea project drags down streamer utilization

Streamer 3D vessel utilization came in below expectations, even though bookings were high going into the quarter. CEO Kristian Johansen attributed the shortfall to operational challenges on a North Sea multi-client project, which was completed in September.

Oslo – October 11, 2026 -- TGS has launched two regional seismic products for Alaska, including a 2D-cubed volume that integrates roughly 667,640 square kilometers of data across the North Slope, Beaufort Sea and Chukchi Sea.

Great Bear Merge 3D stitches legacy surveys across 1,366 square miles

The Great Bear Merge 3D project combines multiple legacy seismic surveys into a single regional dataset covering approximately 1,366 square miles of Alaska's North Slope. TGS reprocessed the data with modern imaging technologies, including full-waveform inversion (FWI). The company says this improves data quality and continuity across historical survey boundaries.

The result is a consistent regional framework for evaluating exploration and development opportunities.
