该发现是通过预探井 15/3-13 S 和 15/3-13 A 获得的，这标志着生产许可证 (PL) 025 中的^第13和第 14^{口勘探井。}

钻探作业使用了 Deepsea Stavanger 钻井平台。初步估计，该发现位于 Draupne 地层内部，可采石油当量储量为 0.1 百万至 1.2 百万^立方米。

此外，Hugin 地层中还发现了 40 万至 130 万立方米^的可采石油当量。许可证持有者将结合该地区的其他勘探潜力评估结果，其中包括 Equinor（持股 36%）、Vôr Energi（持股 25%）、OMV (Norge)（持股 24%）和 Repsol Norge（持股 15%）。

挪威海上管理局在一份声明中表示，这些油井的主要勘探目标是确认 Draupne 组的晚侏罗世储层和 Hugin 组的中侏罗世储层中是否存在石油。

该公司还补充道，次要目标是验证 Ródby 组早白垩世岩石中的储层。15/3-13 S 井在 Draupne 组内部发现了薄层含油砂岩层，但未发现油水接触面。

相比之下，Hugin 组发现了 92 米厚的砂岩，储层性质较差。15/3-13 A 井的勘探成功率更高，在 Draupne 组内部 85 米厚的层段内发现了石油，其中有 13 米厚的中等质量间歇性砂岩层。

两口井均达到了各自的测量深度和垂直深度，其中 15/3-13 S 井位于海平面以下 4,826 米和 4,740 米，而 15/3-13 A 井位于海平面以下 4,900 米和 4,814 米，终止于中侏罗统 Sleipner 组。

上周，Equinor 及其合作伙伴宣布在挪威海布伦斯松西南 260 公里处的 6406/2-L-2 H 井发现天然气和凝析油。

The find was made through wildcat wells 15/3-13 S and 15/3-13 A, marking the 13^th and 14^th exploration wells in production licence (PL) 025.

The Deepsea Stavanger rig was utilised for the drilling operations. Preliminary estimates suggest the discovery holds between 0.1 million and 1.2 million m³ of recoverable oil equivalent within the intra-Draupne Formation.

Additionally, between 0.4 million and 1.3 million m³ of recoverable oil equivalent have been found in the Hugin Formation. The licensees, led by Equinor as the operator with a 36% stake, Vår Energi at 25%, OMV (Norge) holding 24% and Repsol Norge with a 15% interest, will evaluate the results in conjunction with the area's other prospectivity.

In a statement, the Norwegian Offshore Directorate said that the primary exploration target for the wells was to confirm the presence of petroleum in the Late Jurassic reservoir rocks of the intra-Draupne Formation and the Middle Jurassic reservoir rocks of the Hugin Formation.

The secondary target aimed to verify a reservoir in the Early Cretaceous rocks of the Rødby Formation, it added. Well 15/3-13 S identified thin oil-bearing sandstone layers in the intra-Draupne Formation, although the oil/water contact was not encountered.

In contrast, the Hugin Formation revealed 92 m of sandstone with poor reservoir properties. Well 15/3-13 A was more successful, encountering oil within an 85m-thick interval in the intra-Draupne Formation, with 13 m of moderate quality intermittent sandstone layers.

Both wells reached their respective measured and vertical depths, with well 15/3-13 S at 4,826 m and 4,740 m below sea level, and well 15/3-13 A at 4,900 m and 4,814 m below sea level, terminating in the Middle Jurassic's Sleipner Formation.

Last week, Equinor and its partners announced a gas and condensate discovery at well 6406/2-L-2 H, situated 260 km south-west of Brønnøysund in the Norwegian Sea.
