V挪威能源公司 4 月 17 日表示，V 挪威能源公司在北海的 Ringhorne North 发现将支持该运营商在该地区的长期增长计划。

Vongr 表示，位于 PL 956 的最新 Ringhorne North 勘探井估计可采资源量在 13 MMbbl 至 23 MMbbl 之间，并被视为 Balder 地区现有基础设施的回接。

挪威首席运营官 Torger Rased 在一份新闻稿中表示，该公司在挪威大陆架的近场勘探战略正在取得成效。

“我们相信巴尔德地区还有更多价值可以释放，我们正在加强勘探活动，以最大限度地利用现有基础设施创造价值，”他说。

据V挪威人称，这一发现支持了其在Balder地区作为北海长期生产中心的持续发展计划。 

除了释放新资源和探明 Ringhorne 油田的北部延伸之外，V 挪威人表示，Ringhorne North 的发现还降低了该地区可钻探前景的风险，并与附近由 V 挪威人运营的油田（例如 King）开启了潜在的开发协同效应。 -普林斯和埃弗拉-艾文。

V 洛克公司负责勘探和生产的执行副总裁 Rune Oldervoll 在一份新闻稿中表示，巴尔德地区的储量和资源基础几十年来一直稳步增长，该公司相信未来将继续这样做几十年。

“我们的定位是长期生产高价值、低排放的桶，而最新的 Ringhorne North 发现正在支撑我们的长期生产目标，”Oldervoll 说。

Deepsea Yantai 半潜式钻井平台在北海中部钻探了 Ringhorne North 勘探井和另外两口侧钻/评价井，位于 V 缸运营的 Ringhorne 油田以北 8 公里处，水深 127 m。

据挪威近海管理局称，这些是 PL 956 钻探的第一口探井，该项目于 2018 年授予。

25/8-23 S井的主要勘探目标是探明古新世Ty组和三叠系Skagerrak组储层中的石油。次要勘探目标是探明下侏罗统南森组储层中的石油。

25/8-23 S 井在砂岩 Ty 组中遇到了 5 米油柱，储层质量良好至非常好。油/水接触尚未得到证实。 V虫说，发现Nansen组总厚度为15 m，其中12 m为砂岩，储层质量良好至非常好，含有微量石油。该井钻遇斯卡格拉克组，总厚度137 m，其中20 m为中等到差储层质量。该地层是含水的。

25/8-23 S 井钻探至海平面以下 2,454 m MD，终止于基岩。

侧线 25/8-23 A 和 25/8-23 B 旨在分别证明 Ty 组和 Nansen 组储层岩石中的石油。 25/8-23 A 井钻探至海平面以下 2,264 m MD，未遇到 Ty 组砂岩

25/8-23 B 井在 Nansen 组钻遇 8 米油柱。储层总厚度17 m，其中优质层厚度13 m。 25/8-23 B 井钻探至海平面以下 2,206 m ME。

这些井没有进行地层测试，但进行了大量的数据采集和采样。水井也被堵塞并废弃。

Vår Energi’s Ringhorne North discovery in the North Sea will underpin the operator’s long-term growth plans in the region, Vår said April 17.

Vår said the latest Ringhorne North exploration well in PL 956 holds estimated recoverable resources between 13 MMbbl and 23 MMbbl and is being considered as a tieback to existing infrastructure in the Balder area.

Torger Rød, Vår COO, said in a press release that the company’s near-field exploration strategy on the Norwegian Continental Shelf is paying off.

“We believe there is more value to be unlocked in the Balder area, and we are intensifying exploration activities to maximize value creation from the existing infrastructure,” he said.

According to Vår, the discovery supports its plans for continuous development in the Balder area as a long-term production hub in the North Sea. 

In addition to unlocking new resources and proving the northern extension of the Ringhorne Field, Vår said the Ringhorne North discovery also de-risks drillable prospects in the area and opens up potential development synergies with nearby Vår-operated discoveries such as King-Prince and Evra-Iving.

Rune Oldervoll, Vår’s executive vice president for exploration and production, said in a press release the Balder area’s reserves and resource base has steadily grown for decades and that the company is convinced it will continue to do so in the coming decades.

“We are positioned to produce high value, low emission barrels for a long time – and the latest Ringhorne North discovery is underpinning our long-term production targets,” Oldervoll said.

The Deepsea Yantai semisubmersible drilling rig drilled the Ringhorne North exploration well and two additional side-track/appraisal wells in the Central North Sea, 8 km north of the Vår-operated Ringhorne Field, in 127 m water depth.

According to the Norwegian Offshore Directorate, these are the first exploration wells to be drilled in PL 956, which was awarded in 2018.

The primary exploration target for well 25/8-23 S was to prove petroleum in reservoir rocks in the Ty Formation in the Paleocene and in the Skagerrak Formation in the Triassic. The secondary exploration target was to prove petroleum in reservoir rocks in the Nansen Formation in the Lower Jurassic.

Well 25/8-23 S encountered a 5-m oil column in the Ty Formation in sandstone with good to very good reservoir quality. The oil/water contact was not proven. The Nansen Formation was encountered with a total thickness of 15 m, of which 12 m were sandstone with good to very good reservoir quality with traces of oil, Vår said. The well encountered the Skagerrak Formation with a total thickness of 137 m, of which 20 m were of moderate to poor reservoir quality. The formation was aquiferous.

Well 25/8-23 S was drilled to 2,454 m MD below sea level and was terminated in basement rock.

Sidetracks 25/8-23 A and 25/8-23 B were intended to prove petroleum in reservoir rocks in the Ty Formation and Nansen Formation, respectively. Well 25/8-23 A was drilled to 2,264 m MD below sea level and did not encounter sandstone in the Ty Formation

Well 25/8-23 B encountered an 8-m oil column in the Nansen Formation. The reservoir showed a total thickness of 17 m, of which 13 m were of quality. Well 25/8-23 B was drilled to 2,206 m ME below sea level.

The wells were not formation-tested, but extensive data acquisition and sampling was undertaken. The wells were also plugged and abandoned.

Vår operates PL 956 with 50% interest on behalf of partners, Aker BP ASA with 20%, Harbour Energy Norge AS with 15% and Sval Energi AS with 15%.
