Harbour Energy and its partners have confirmed a gas discovery in well 15/9-25 in the North Sea, the Norwegian Offshore Directorate announced March 13.

Gas was first proven in wells 16/7-2 and 16/7-10, drilled in 1982 and 2011, respectively. The 15/9-25 well is the first one to be drilled in PL 1138, which was awarded in 2021.

The overall gas volume is calculated at between 1 MMcm and 3 MMcm of recoverable oil equivalent. 

Licensees Harbour Energy, Sval Energi and Aker BP will consider whether to tie the discovery into existing infrastructure in the area.

Water depth at the site is 84 m. The well has been permanently plugged and abandoned.

Tyra Nearing Production Start Up

The Tyra 2 redevelopment project in the Danish North Sea is on track to begin production by March 31 following successful methanol loading, partner BlueNord announced March 12.

LLOG Taps ABL for Salamanca Services

LLOG Exploration awarded ABL a contract for marine warranty survey (MWS) services for the subsea development of the Salamanca development project in the Gulf of Mexico, ABL announced March 12.

ABL will review technical documents and approve critical procedures, drawings and documentation and suitability inspections of the proposed fleet for subsea operations. ABL will also be onsite to review and approve transportation and mobilization operations of project assets.

The Salamanca project includes the build-out of the Leon and Castille fields in water depths of 5,900 ft to 6,560 ft. The subsea portion of the project includes three infield subsea pipeline systems, as well as the design and fabrication of subsea structures. The pipelines will run from the wellsite to the Salamanca floating production facility.

Equinor Awards Shearwater 4D Monitoring Work

Shearwater GeoServices Holding announced March 13 it had won two 4D monitoring projects from Equinor for the Mariner Field in the U.K. North Sea and the Heidrun field in the Norwegian Sea.

Shearwater will deploy its Isometrix technology for both surveys, applying 4D seismic monitoring to detect reservoir dynamics over time for optimizing reservoir management and enhancing production efficiency. This will be the fourth Isometrix deployment for Mariner, following surveys in 2020 and 2022, and the third for Heidrun, following surveys in 2018 and 2021.

The surveys are expected to take two months and will be carried out by the SW Amundsen and an undershoot vessel.

Parker Wellbore and TDE entered into an alliance to perform pilot projects and commercialize TDE’s proprietary tde powerline downhole power and data highway services globally, the companies announced March 13.

Tde powerline is a downhole high-power, high-bandwidth data highway enabling intelligent digital drilling systems, which enables AI-driven solutions and drilling automation. Tde powerline wired drill pipe technology provides electric power from the surface via the drill string to the BHA and increases downhole data streaming while drilling to levels not seen today, the companies said. 

Under the deal, Parker Wellbore has exclusive rights to deploy tde powerline. A pilot project is planned in the Middle East, a Parker Wellbore spokesperson told Hart Energy.
