V挪威能源公司在斯塔万格西北200公里处的25/7-12 S和A井钻探，两口井都是干的。

“ubert”和“agellan”远景区是在2017年颁发的917号生产许可证中进行钻探的。钻井作业使用的是Deepsea Yantai钻井平台。

这是该生产许可证中的第三口井和第四口井。近年来，该领域取得了多项发现。这里基础设施十分发达。 V挪威能源公司经营Balder和Ringhorne East油田，而Equinor则经营Grane、Svalin和Breidablikk油田。

地质信息

25/7-12 S预探井的主要和次要勘探目标分别是在Hermod和Sele地层的古新世储层中探明石油。

25/7-12 A 预探井的主要和次要勘探目标分别是在 Balder 和 Horda 地层的始新世储层岩石中探明石油。

25/7-12 S井钻遇Hermod地层，总厚度34米，其中砂岩30米，储集层品质良好。井干了。

25/7-12 A 井钻遇 Horda 地层，总厚度 49 米，其中约 2 米为砂岩，储层质量良好至非常好，含微量天然气。 Balder地层总厚度为85米，其中约11米为砂岩层，储层质量非常好。 Hermod 地层总厚度为 36 米，其中 14 米储层质量非常好，并含有微量碳氢化合物。

25/7-12 S井钻探深度和垂直深度分别为海平面以下2241米和1914米，终止于古新统塞勒地层。
25/7-12A井钻探深度和垂直深度分别为海平面以下2023米和1962米，终止于古新世塞勒地层。
现场水深127米。这些井已被永久堵塞并废弃。

Vår Energi drilled wells 25/7-12 S and A 200 kilometres northwest of Stavanger, both of which were dry.

The “Hubert” and “Magellan” prospects were drilled in production licence 917, awarded in 2017. The Deepsea Yantai rig was used for the drilling operation.

These were the third and fourth wells in this production licence. Multiple discoveries have been made in this area in recent years. Infrastructure here is well developed. Vår Energi operates the Balder and Ringhorne East fields, while Equinor operates the Grane, Svalin and Breidablikk fields.

Geological information

The primary and secondary exploration targets for wildcat well 25/7-12 S were proving petroleum in Palaeocene reservoir rocks in the Hermod and Sele formations, respectively.

The primary and secondary exploration targets for wildcat well 25/7-12 A were proving petroleum in Eocene reservoir rocks in the Balder and Horda formations, respectively.

Well 25/7-12 S encountered the Hermod formation with a total thickness of 34 metres, of which 30 metres were sandstone rocks of good reservoir quality. The well was dry.

Well 25/7-12 A encountered the Horda formation with a total thickness of 49 metres, of which about two metres was sandstone rocks with good to very good reservoir quality and with traces of gas. The Balder formation was encountered with a thickness of 85 meters in total, of which about 11 metres was a sandstone layer with very good reservoir quality. The Hermod formation was encountered with a total thickness of 36 metres, of which 14 metres was of very good reservoir quality and with traces of hydrocarbons.

Well 25/7-12 S was drilled to respective measured and vertical depths of 2241 metres and 1914 metres below sea level, and was terminated in the Sele formation in the Palaeocene.
Well 25/7-12 A was drilled to respective measured and vertical depths of 2023 metres and 1962 metres below sea level, and was terminated in the Sele formation in the Palaeocene.
Water depth at the site is 127 metres. The wells have been permanently plugged and abandoned.
