Equinor Energy AS 在 30/12-3 S 探井中发现石油

Equinor Energy AS 在北海 30/12-3 S 探井中发现了石油。该井还包括一条侧线 30/12-3 A，该侧线是干的。

这些井位于奥塞贝格以南约 40 公里、卑尔根以西 150 公里处。此次钻探由深海斯塔万格钻机进行。

Equinor代表Aker BP钻探该井，该公司是272 B生产许可证的运营商。这是该生产许可证的第一口井。

Aker BP和Equinor各拥有该生产许可证50%的所有权，该许可证于2018年APA颁发。该生产许可证是Munin油田的一部分，该油田于2011年发现。当局批准了开发和运营计划（PDO） ）于 2023 年 6 月为 Munin 提供。

30/12-3 S 井探明可采油当量为 0.15 至 55 万标准立方米。

初步计算表明，按照当前的价格假设，该发现无法盈利。

地质资料

30/12-3 S 和 30/12-3 A 预探井的目的是探明中侏罗统塔伯特组储层岩石中的石油。

30/12-3 S 井在 Tarbert 组钻遇 3.5 m 油柱，属于砂岩油藏，油藏质量中等。Tarbert组厚约195 m，其中97 m为砂岩，储层质量为中良。油/水接触发生在海平面以下 3110 米处。

Ness组总厚度约163 m，其中19 m为砂岩储层，储层质量中等。

30/12-3A井钻遇塔伯特组，厚度约216 m，其中19 m为砂岩，储集层质量较差。Ness组总厚度约50 m，其中11 m为砂岩储层，储层质量中等。井干了。

这些井没有进行地层测试，但进行了数据采集。

30/12-3 S 井的测量深度和垂直深度分别为海平面以下 3663 m 和 3465 m，终止于 Drake 地层。30/12-3 A 井的测量深度和垂直深度分别为海平面以下 4520 m 和 3718 m，终止于 Ness 地层。该地区水深106 m。该井现已被永久堵塞并废弃。

Equinor Energy AS discovers oil in exploration well 30/12-3 S

Published by , Deputy Editor
Oilfield Technology,

Equinor Energy AS has discovered oil in exploration well 30/12-3 S in the North Sea. The well also included a sidetrack, 30/12-3 A, which was dry.

The wells were drilled about 40 km south of Oseberg and 150 km west of Bergen. The drilling was conducted by the Deepsea Stavanger drilling rig.

Equinor drilled the well on behalf of Aker BP, which is the operator of production licence 272 B. This is the first well in the production licence.

Aker BP and Equinor each have ownership interests of 50% in the production licence, which was awarded in APA 2018. The production licence is part of the Munin field, which was discovered in 2011. The authorities approved the plan for development and operation (PDO) for Munin in June 2023.

Between 0.15 and 0.55 million standard m3 of recoverable oil equivalent was proven in well 30/12-3 S.

Preliminary calculations show that the discovery is not profitable with current price assumptions.

Geological information

The objective of wildcat wells 30/12-3 S and 30/12-3 A was to prove petroleum in Middle Jurassic reservoir rocks in the Tarbert Formation.

Well 30/12-3 S encountered a 3.5 m oil column in the Tarbert Formation, in a sandstone reservoir with moderate reservoir quality. The Tarbert Formation was about 195 m thick, 97 m of which was sandstone rocks with moderate-good reservoir quality. The oil/water contact was encountered 3110 m below sea level.

The Ness Formation was about 163 m thick in total, 19 m of which was a sandstone reservoir with moderate reservoir quality.

Well 30/12-3 A encountered the Tarbert Formation with a thickness of about 216 m, 19 m of which was sandstone rocks with poor reservoir quality. The Ness Formation was about 50 m thick in total, 11 m of which was a sandstone reservoir with moderate reservoir quality. The well was dry.

The wells were not formation-tested, but data acquisition was undertaken.

Well 30/12-3 S was drilled to measured and vertical depths of 3663 m and 3465 m below sea level, respectively, and was terminated in the Drake Formation. Well 30/12-3 A was drilled to measured and vertical depths of 4520 m and 3718 m below sea level, respectively, and was terminated in the Ness Formation. Water depth in the area is 106 m. The well has now been permanently plugged and abandoned.
