这些井位于北海奥塞伯格油田西北约10公里处、卑尔根西北150公里处。

30/5-4 S 井的主要勘探目标是探明中侏罗统塔伯特组（布伦特群）储层岩石中的石油。该井的次要勘探目标是探明中侏罗统 Ness 组（布伦特群）储层岩石中的石油。

30/5-4 A 评价井的目的是在 Tarbert 地层进行地层测试。

30/5-4 S井在Tarbert组钻遇气/凝析油柱长约100米，总厚度200米，砂岩层厚96米，储层质量较差。没有遇到气体/水接触。

30/5-4 A 井在 Tarbert 地层中遇到了约 90 米的天然气/凝析油柱。共钻探地层150米，砂岩层厚90米，储层质量较差。没有遇到气体/水接触。

尼斯地层干燥，含有石油痕迹。

初步估计该发现的可采油当量为 1.5 至 650 万 Sm ^{3 。}被许可人将对这一发现进行评估，以期采取进一步的后续行动。

在井中进行了广泛的数据采集和取样，包括在 30/5-4 A 中成功进行了地层测试。Tarbert 地层地层测试的平均产量约为 60 000 Sm ³天然气和 45 Sm ³石油。每个流量日的冷凝水通过 10/64 英寸喷嘴开口。

这是2020年APA颁发的1100号生产许可证的前两口探井。

30/5-4 S井垂直钻探深度为海平面以下5003米，终止于中侏罗统Ness组。30/5-4 A 井分别钻探至海平面以下 4726 米和 4946 米的垂直深度，终止于中侏罗统 Tarbert 组。

现场水深95米。这些油井现在将被永久堵塞并废弃。

30/5-4 S 井和 30/5-4 A 井由 Nobel Intrepid 钻井设施钻探，目前将继续前往苏格兰。

The wells were drilled about 10 kilometres northwest of the Oseberg field in the North Sea and 150 kilometres northwest of Bergen.

The primary exploration target for well 30/5-4 S was to prove petroleum in Middle Jurassic reservoir rocks in the Tarbert Formation (the Brent Group). The secondary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks in the Ness Formation (the Brent Group).

The objective of appraisal well 30/5-4 A was to conduct a formation test in the Tarbert Formation.

Well 30/5-4 S encountered a gas/condensate column of about 100 metres in the Tarbert Formation, which has a total thickness of 200 metres, and sandstone layers totalling 96 metres, with poor reservoir quality. The gas/water contact was not encountered.

Well 30/5-4 A encountered a gas/condensate column of about 90 metres in the Tarbert Formation. A total of 150 metres of the formation was drilled, with sandstone layers totalling 90 metres with poor reservoir quality. The gas/water contact was not encountered.

The Ness Formation is dry, with traces of petroleum.

Preliminary estimates place the size of the discovery between 1.5 and 6.5 million Sm³ of recoverable oil equivalent. The licensees will assess the discovery with a view toward further follow-up.

Extensive data acquisition and sampling have been conducted in the wells, including a successful formation test in 30/5-4 A. The average production rate from the formation test in the Tarbert Formation was around 60 000 Sm³ of gas and 45 Sm³ of condensate per flow day through a 10/64-inch nozzle opening.

These are the first two exploration wells in production licence 1100, which was awarded in APA 2020.

Well 30/5-4 S was drilled to a vertical depth of 5003 metres below sea level and was terminated in the Middle Jurassic in the Ness Formation. Well 30/5-4 A was drilled to respective vertical and measured depths of 4726 and 4946 metres below sea level, and was terminated in the Middle Jurassic in the Tarbert Formation.

Water depth at the site is 95 metres. The wells will now be permanently plugged and abandoned.

Wells 30/5-4 S and 30/5-4 A were drilled by the Nobel Intrepid drilling facility, which will now proceed on to Scotland.
