挪威石油天然气公司 Aker BP 和 Equinor 在北海 Munin 油田附近勘探了新的石油储量。 这是挪威近海管理局（NOD）新闻部门报道的。

30/12区块勘探钻探

挪威海洋工业局 (NOIA)（前身为挪威石油安全局 (PSA)）已向 Aker BP 授予 2023 年在北海挪威海域 30/12 区块勘探钻探许可证。 勘探井 30/12 -3 S 和 30/12-3 A 钻探地点位于 Oseberg 油田以南 40 公里、卑尔根以西 150 公里处。 30/12-3 S 和 30/12-3 A 探井的目的是识别中侏罗世储层岩石（塔伯特组）中的石油矿床。

使用半潜式钻井平台 (SSDR) Deepsea Stavanger 进行钻井：

  • 2010年在韩国造船厂DSME建造；
  • 长度～118.6 m；
  • 宽度～96.7 m；
  • 最大钻孔深度——10,670 m；
  • 归 Odfjell 钻井公司所有； 2017 年 4 月获得 PSA 的合规性批准 (AoC)。

钻井工作由 Equinor 代表 Aker BP 进行， Aker BP 是 272 B 生产许可证的运营商。Aker BP 和 Equinor 在 272 B 中拥有同等股份 (50%)，该许可证是在预定义区域 (APA) 许可授予后颁发的2018 年一轮。 生产许可证还涵盖 2011 年发现的 Munin 油田。 挪威当局已于 2023 年 6 月批准了 Munin 的开发和运营计划 (PDO)。

井 30/12-3 S

  • 钻探深度达 3663 米（海平面以下 3465 米）；
  • 在中等储层品质的砂岩中，以 3.5 层距发现塔伯特组油藏；
  • 在海平面以下3110米深处发现油水接触面；
  • 可采储量范围为 0.15 至 55 万立方厘米 oe。
  • 据初步测算，在目前的价格假设下，开仓是无利可图的。

侧井 30/12-3 A

  • 钻孔深度为4520米（海平面以下3718米），
  • 在Tar​​bert地层，该井钻遇19 m储层质量较差的砂岩，
  • 结果井已经干了。

据NOD称，这些井没有经过测试，但收集了数据。

早些时候，人们了解到，挪威国家石油公司在北海马丁林格油田以北约 7 公里、卑尔根以西 180 公里处钻探的 30/4-4 号探井也已干涸。

让我们提醒您，2024年1月16日，挪威能源部总结了APA-2023的结果。 Equinor 在获得的许可证数量方面成为领先者——作为运营商获得了 14 个许可证，作为合作伙伴获得了 25 个许可证。 其中北海有18个生产许可证，挪威海有13个，巴伦支海有8个。 随后Equinor宣布有必要继续积极进行地质勘探，以减少海上产量的下降。 Aker BP ASA 紧随 Equinor 后，获得 27 个许可证，其中包括 17 个运营商许可证，位居第二。

Aker BP And Equinor’s North Sea Exploration Drilling Results Were Unsatisfactory

— January 25, 2024

Norwegian oil and gas companies Aker BP and Equinor have explored new oil reserves near the Munin field in the North Sea. This was reported by the press service of the Norwegian Offshore Directorate (NOD).

Exploration drilling at block 30/12

The Norwegian Ocean Industry Authority (NOIA), formerly known as the Norwegian Petroleum Safety Authority (PSA), has granted Aker BP an exploration drilling permit for block 30/12 in the Norwegian sector of the North Sea in 2023. Exploration wells 30/12-3 S and 30/12-3 A were drilled 40 km south of the Oseberg field and 150 km west of Bergen. The purpose of exploration wells 30/12-3 S and 30/12-3 A was to identify oil deposits in reservoir rocks of Middle Jurassic age (Tarbert Formation).

Drilling was carried out using a semi-submersible drilling rig (SSDR) Deepsea Stavanger:

  • built in 2010 at the South Korean shipyard DSME;
  • length – 118.6 m;
  • width – 96.7 m;
  • maximum drilling depth – 10,670 m;
  • owned by Odfjell Drilling; approval of conformity (AoC) from PSA was received in April 2017.

The drilling work was carried out by Equinor on behalf of Aker BP, which is the operator of production license 272 B. Aker BP and Equinor own equal shares (50%) in 272 B, issued following the Awards in predefined areas (APA) licensing round in 2018. The production license also covers the Munin field, discovered in 2011. Norwegian authorities have approved a plan of development and operation (PDO) for Munin in June 2023.

Well 30/12-3 S

  • was drilled to a depth of 3663 m (3465 m below sea level);
  • discovered an oil reservoir in the Tarbert Formation at intervals of 3.5 in sandstones with medium reservoir quality;
  • an oil-water contact was discovered at a depth of 3110 m below sea level;
  • recoverable reserves range from 0.15 to 0.55 million cm3 oe.
  • according to preliminary calculations, the opening is unprofitable under current price assumptions.

Lateral well 30/12-3 A

  • the drilling depth was 4520 m (3718 m below sea level),
  • in the Tarbert formation, the well encountered 19 m of sandstone with poor reservoir quality,
  • the well turned out to be dry.

According to NOD, the wells were not tested, but data was collected.

Earlier it became known that the exploration well 30/4-4, drilled by the Norwegian Equinor approximately 7 km north of the Martin Linge field in the North Sea and 180 km west of Bergen, also turned out to be dry.

Let us remind you that on January 16, 2024, the Norwegian Ministry of Energy summed up the results of APA-2023. Equinor became the leader in the number of licenses received – 14 as an operator, 25 as a partner. Including 18 production licenses in the North Sea, 13 in the Norwegian Sea and 8 in the Barents Sea. Then Equinor announced that it was necessary to continue active geological exploration in order to reduce the decline in offshore production. Aker BP ASA followed Equinor with 27 licenses, including 17 operator licenses, finishing in 2nd place.
