Equinor 在北海 Svalin 油田的 25/11-H-1 H 井中发现了石油。

被许可人将考虑该发现是否足以为生产带来利润。

初步计算显示，可采油当量为0至10万标准立方米，相当于0至60万桶。

这一发现是在拥有生产许可证 169 的 Deepsea Aberdeen 钻机的一口开发井中发现的。

地质信息
Svalin 油田于 1992 年在 Heimdal 和 Balder 地层的古新世至始新世早期的砂岩中得到证实，并自 2014 年以来一直在生产。该字段由两个独立的结构组成； Svalin C 和 Svalin M。Svalin C 是通过与 Grane 装置相连的海底模板开发的，Svalin M 是通过 Grane 钻探的多分支井开发的。

开发井 25/11-H-1 H 在薄砂岩层 (< 3 m) 中发现了石油，该层位于 Rogaland 群的 Balder 组，储层质量非常好。据推测，Balder 地层中的石油与 Svalin C 构造上 Heimdal 地层周围的储层砂体存在压力连通。没有遇到油/水接触。

Equinor has made an oil discovery in well 25/11-H-1 H at the Svalin field in the North Sea.

The licensees will consider whether the discovery is sufficiently profitable for production.

Preliminary calculations show between 0 and 0.1 million standard cubic metres of recoverable oil equivalent, which is the equivalent of between 0 and 0.6 million barrels.

The discovery was made in a development well with the Deepsea Aberdeen rig in production licence 169.

Geological information
The Svalin field was proven in 1992 in sandstone from the Palaeocene to early Eocene in the Heimdal and Balder Formations, and has been in production since 2014. The field consists of two separate structures; Svalin C and Svalin M. Svalin C has been developed with a subsea template tied back to the Grane installation and Svalin M has been developed with a multi-branch well drilled from Grane.

Development well 25/11-H-1 H encountered oil in thin sandstone layers (< 3 m) with very good reservoir quality in the Balder Formation, which is part of the Rogaland Group. The oil in the Balder Formation is presumed to be in pressure communication with surrounding reservoir sands in the Heimdal Formation on the Svalin C structure. The oil/water contact was not encountered.
