Norwegian oil and gas operator DNO ASA has appointed Birgitte Wendelbo Johansen as its new Chief Financial Officer, effective 1 November 2025. She will replace Haakon Sandborg, who is stepping down after 24 years in the role, marking a significant leadership transition for the Oslo-listed energy company.

Ms. Johansen joins DNO from Reach Subsea ASA, an Oslo Børs-listed oil services company where she served as Chief Financial Officer since 2012. Prior to her tenure at Reach Subsea, she built a successful career in banking with specialization in shipping and energy sectors, bringing substantial financial expertise to her new position.

Mr. Sandborg, who joined DNO from corporate finance roles at DNB and the Aker oil services group, is the company's longest-serving staff member. During his tenure, DNO completed 21 successful bond placements with no waivers, amendments, or defaults, a track record that incoming CFO Johansen described as difficult to overstate in terms of contribution to the company.

The transition will see Mr. Sandborg remain at DNO in a senior advisory role until the end of the year, ensuring a smooth handover. DNO ASA, founded in 1971 and listed on the Oslo Stock Exchange, maintains operations in the Middle East, North Sea, and West Africa, with stakes in onshore and offshore licenses across multiple regions including the Kurdistan region of Iraq, Norway, the United Kingdom, Côte d'Ivoire, and Yemen.

TGS, the Oslo-based energy data provider, has been awarded a significant ocean bottom node (OBN) acquisition contract in the Gulf of Mexico, marking another strategic win in one of the company's core markets. The 4D monitor survey is scheduled to commence in the fourth quarter of 2025 and will span approximately four and a half months. This contract represents continued confidence in TGS's capabilities from the international oil company client, though the specific customer identity remains undisclosed.

The contract was notably absent from TGS's booked position disclosed in the company's second quarter 2025 presentation, indicating a recent acquisition for the seismic data specialist. The Gulf of Mexico remains a critical region for offshore energy production, and 4D seismic monitoring plays an essential role in optimizing reservoir management and production efficiency for major operators in the region.

Kristian Johansen, CEO of TGS, emphasized the significance of securing business from repeat customers, stating that the client values TGS's OBN technology and proven track record of project execution. "The client is confident we will deliver high-quality data and insights to optimize production from one of their highest producing facilities in the Gulf of Mexico," Johansen commented, highlighting the operational importance of the project for the customer's production optimization efforts.

TGS's expertise in OBN technology positions the company as a trusted partner for international oil companies seeking to maximize recovery from existing assets. The 4D seismic approach allows operators to monitor reservoir changes over time, providing critical data for production optimization decisions. This latest contract win reinforces TGS's strong position in the Gulf of Mexico market and demonstrates the ongoing demand for advanced seismic monitoring solutions in mature offshore basins.
