The wells were drilled about 8 kilometres northwest of 25/8-11 Ringhorne on the Balder field in the North Sea, about 200 kilometres west of Stavanger.
The 25/8-19 S (Iving) discovery was proven in 2019 in reservoir rocks from the Palaeocene (Heimdal Formation), the Early Jurassic (Statfjord Group), the Late Triassic (Skagerrak Formation) and in basement rock.
Before appraisal wells 25/8-21 S and 25/8-22 S were drilled, the operator’s resource estimate for the discovery was between 2 and 11 million standard cubic metres (Sm3) of recoverable oil equivalent in the Skagerrak formation.
The primary exploration target for well 25/8-21 S was to encounter the oil/water contact in sandstones in the Skagerrak Formation. The secondary exploration target was to evaluate the petroleum potential in the basement rock reservoir.
The primary exploration target for well 25/8-22 S was to evaluate the petroleum potential in sandstones in the lower part of the Statfjord Group and in the Skagerrak Formation. The secondary exploration target was to evaluate the petroleum potential in the Heimdal Formation and basement rock.
The results show that the appraisal wells will lead to a downward adjustment of the resource estimate in the Skagerrak Formation in 25/8-19 S (Iving), but it is still too early to give an updated estimate for the discovery.
The licensees will assess the results in the Skagerrak Formation in combination with other petroleum-bearing levels and discoveries in the area for further follow-up.

Wellify is the first product coming out of Cuttings Insight, a non-commercial collaboration project initiated by Pandion Energy in 2020, with DNO Norge AS and Spirit Energy Norway AS as partners and Itera ASA as technical provider. The launch of Wellify marks the end of a successful development and test period. The product is now daily in use with all three companies, demonstrating the rapid acceptance of new digital solutions when user driven.
The idea behind Wellify was to provide the geoscientists with easy access to the high-resolution photos and mineral analysis coming from another joint industry collaboration project, namely the Released Well Initiative (RWI). With cuttings samples from more than 1,900 wells on the Norwegian continental shelf being digitalised, on average 300 – 400 samples per well, this project has created more than two million files and 30 terabytes of data.
Bente Flakstad Vold, VP Exploration & Appraisal at Pandion Energy says:
Cuttings data has traditionally been an under-utilized and hidden data type. Wellify makes the digital cuttings data accessible and brings new valuable and insightful information about the subsurface.
Wellify provides instant and dynamic access to the photos and data from the Released Well Initiative. As all files are streamed through a cloud-based solution, users get immediate access without having to download large quantities of RWI data sets or to install and integrate a new software into existing systems.
The project is currently enrolling new members and will enter the next development phase, further investigating additional functionality and potential uses of the data set from the Released Well Initiative.
The Hod field will be developed with a normally unmanned installation (NUI), Hod B, which will be remotely operated from Valhall and run on power from shore, yielding close to zero CO2 emissions during normal operations.
Hod is one of the first projects to be realised under the temporary changes to the Norwegian petroleum Tax Act introduced in June 2020 following the COVID-19 breakout. The field is expected to generate more than NOK 6 billion of tax revenues during its lifetime. Including ripple effects, the project is estimated to create around 5 000 man-years of employment during the execution phase. 75 per cent of the contract values for construction of the Hod B platform and subsea installations have gone to Norwegian supplier companies.
Both the jacket and topsides are being built at Aker Solutions in Verdal, and the work has secured a number of jobs at the yard. The Hod B platform is being delivered by the fixed facilities alliance between the operator Aker BP, Aker Solutions and ABB. The alliance also successfully delivered the Valhall Flank West NUI in June 2019.
Hod B is expected to contribute 40 million barrels of oil equivalent and will be important for Valhall to reach the ambition of a total of two billion produced barrels from the area. Production is scheduled to start in the first quarter of 2022.
The Hod field has produced oil in the past from what was the first unmanned platform on the Norwegian continental shelf. The new Hod platform is a copy of Valhall Flank West.
The Hod B topside is scheduled to sail from the Verdal yard in August. At the same time work is under way to plan remaining activities to complete the project. Multiple subsea campaigns will be conducted to install and connect the gas lift pipe, production flowline and umbilical. Integration work is under way on Valhall and the Maersk Invincible drilling rig is scheduled to start drilling production wells this autumn.
Aker BP ASA is the operator of the Valhall and Hod fields. Pandion Energy AS holds 10% ownership interest in the Valhall area, including licenses PL006B, PL033 and PL033B.
