这些井位于 Troll 油田西北约 25 公里处、卑尔根西北 150 公里处。

35/10-10 S 井的主要勘探目标是探明布伦特群 Etive 和 Oseberg 地层中侏罗统储层岩石中的石油。35/10-10 S井的二次勘探目标是探明早侏罗世库克组含油气。

35/10-10A评价井的目的是在构造上较低的位置遇到石油-水接触面，并从含水层收集液体样品。

35/10-10 S 井在 Ness、Etive 和 Oseberg 地层钻遇 210 m 凝析气柱，其中 90 m 为砂岩储层，储层质量较差至中等。在Cook组，该井钻遇70 m凝析气柱，其中23 m为砂岩储层，储层质量较差。敦林群早侏罗世阿蒙森组也发现13 m油柱，其中13 m为砂岩油藏，储层质量较差。

井中35/10-10 A在结构上钻了较低，位于主井以西900 m，在NESS，Etive，Oseberg和Cook地层中遇到了240 m的气体键合柱，其中50 m是砂岩储层，很差，可中等储层质量。库克地层中的水来自海平面以下 4158 米的垂直深度。

初步估计表明，发现的大小在9至4600万平方米的可回收油当量之间。被许可人将启动早期开发研究，并考虑在该发现中增加评价井。

35/10-10 S井垂直钻探深度为海平面以下4030 m，终止于早侏罗世阿蒙森组。已经进行了广泛的数据采集和采样。

井35/10-10 A被钻至海平面以下4212 m的垂直深度，并终止于早期侏罗纪的厨师地层。

这是2021年APA颁发的1148号生产许可证中的第一口和第二口探井。

现场水深360 m。井已经永久堵塞和废弃。

井是由深海Yantai钻井设施钻探的，该设施现在将在北海的生产许可证984中钻25/7-11 s的野猫井，DNO NORGE作为操作员。

The wells were drilled about 25 km northwest of the Troll field and 150 km northwest of Bergen.

The primary exploration target for well 35/10-10 S was to prove petroleum in Middle Jurassic reservoir rocks in the Etive and Oseberg formations in the Brent Group. The secondary exploration target for well 35/10-10 S was to prove petroleum in the Early Jurassic Cook Formation.

The objective of appraisal well 35/10-10 A was to encounter the petroleum-water contact in a lower position on the structure, and to collect liquid samples from the aquifer.

Well 35/10-10 S encountered a 210 m gas-condensate column in the Ness, Etive and Oseberg formations, of which a total of 90 m was sandstone reservoir with poor to moderate reservoir quality. In the Cook Formation, the well encountered a 70 m gas-condensate column, of which a total of 23 m was sandstone reservoir with poor reservoir quality. A 13 m oil column was also encountered in the Early Jurassic Amundsen Formation in the Dunlin Group, whereof a total of 13 m was sandstone reservoir with poor reservoir quality.

Well 35/10-10 A was drilled lower on the structure, 900 m west of the main well and encountered a 240 m gas-condensate column in the Ness, Etive, Oseberg and Cook formations, whereof 50 m was sandstone reservoir with poor to moderate reservoir quality. Water was encountered in the Cook Formation from a vertical depth of 4158 m below sea level.

Preliminary estimates indicate the size of the discovery is between 9 and 46 million m3 of recoverable oil equivalent. The licensees will initiate early-phase development studies, and are considering additional appraisal wells in the discovery.

Well 35/10-10 S was drilled to a vertical depth of 4030 m below sea level, and was terminated in the Amundsen Formation in the Early Jurassic. Extensive data acquisition and sampling have been carried out.

Well 35/10-10 A was drilled to a vertical depth of 4212 m below sea level, and was terminated in the Cook Formation in the Early Jurassic.

These are the first and second exploration wells in production licence 1148, awarded in APA2021.

Water depth at the site is 360 m. The wells have been permanently plugged and abandoned.

The wells were drilled by the Deepsea Yantai drilling facility, which will now drill wildcat well 25/7-11 S in production licence 984 in the North Sea, where DNO Norge AS is the operator.
