Equinor 及其合作伙伴在北海的“Lit”勘探区钻探了一口干井。25

/11-30 S 号探井是在 169 号生产许可证（链接至 FactPages）内钻探的，该许可证于 1991 年在挪威大陆架 (NCS) 第 13 轮许可中授予。这是在该生产许可证内钻探的第 16 口勘探井。

“Lit”勘探区位于北海中部 Svalin 油田的南部，距离 Balder 油田约 9 公里。

该井由 Deepsea Atlantic 钻井平台钻探，该钻井平台目前正在钻探 554 号生产许可证内的 34/6-8 S 号探井，Equinor 是该井的作业者。

地质信息
该井的目标是探明古新世至早始新世 Balder 组的 Odin 砂岩中的石油。

该井未能按计划在 Balder 组中钻探砂岩。然而，该井确实钻遇了早始新世的弗里格组。弗里格组的砂岩厚度约为3米，储层质量极佳。没有碳氢化合物的痕迹，该井被归类为干井。25

/11-30 S井的垂直深度约为海平面以下1808米，终止于晚古新世的利斯塔组。该井眼的总测量深度为2606米（MD）。

现场水深122米。该井已被永久封堵并废弃。

Equinor and its partners have drilled a dry well on the «Lit» prospect in the North Sea.

Wildcat well 25/11-30 S was drilled in production licence 169 (link to FactPages), which was awarded in the 13th licensing round on the Norwegian continental shelf (NCS) in 1991. This is the 16th exploration well drilled in this production licence.

The «Lit» prospect is located in the southern part of the Svalin field in the central part of the North Sea, about 9 kilometres from the Balder field.

The well was drilled by the Deepsea Atlantic rig, which is now drilling wildcat well 34/6-8 S in production licence 554, where Equinor is the operator.

Geological information
The well's objective was to prove petroleum in Odin sandstone belonging to the Balder Formation in Palaeocene to Early Eocene.

The well did not encounter sandstone in the Balder Formation as planned. However, the well did encounter the Frigg Formation from the Early Eocene. The sandstone in the Frigg Formation was about three metres thick and had very good reservoir quality. There were no traces of hydrocarbons, and the well is classified as dry.

Well 25/11-30 S was drilled to a vertical depth of about 1808 metres below sea level and was terminated in the Lista Formation in the Late Palaeocene. The total measured depth for the wellbore was 2606 metres (MD).

Water depth at the site is 122 metres. The well has been permanently plugged and abandoned.
