挪威国家石油公司（Equinor）及其合作伙伴在卑尔根西北190公里处的古尔法克斯（Gullfaks）附近的“Granat”勘探区发现了油气资源。

在152号生产许可证区域内，为配合古尔法克斯卫星层（Gullfaks Satellites）的石油开发井（33/12-N-3 IH）的钻探，钻探了33/12-N-3 HH和

33/12-N-3 GH两口探井。此次发现位于277号生产许可证区域内的33/12-N-3 HH井，该许可证于2002年授予（2001年北海油气开发许可证）。这是该生产许可证区域内的第一口勘探井。33/12-N-3 GH探井的目标区域位于152号生产许可证区域内，但该井未发现油气资源。152号生产许可证于1988年在挪威大陆架（NCS）第12轮油气勘探许可证招标中授予。

初步估计显示，“Granat”油田的可采油当量（oe）在0.2至0.6百万标准立方米（Sm3）之间，相当于1.3至3.8百万桶油当量。

许可证持有者Equinor（作业者）、Petoro和OMV正在考虑将该油田与Gullfaks地区的现有基础设施连接起来。

这些井是从050号生产许可证区域使用Askeladden钻机钻探的。
地质信息：
33/12-3GH (N2A)井的目标是探明Tarbert组储层岩石中的油气，次要目标是Ness组和Etive组，所有这些地层均属于中侏罗世布伦特组。

该井钻探至塔伯特组（Tarbert Formation）共115米，其中48米为砂岩层，储层性质中等至良好；钻探至尼斯组（Ness Formation）共59米，其中10米为砂岩层，储层性质良好。两个地层均为含水层。已采集包括压力数据在内的数据。

33/12-3-GH井的测量深度和垂直深度分别为6708米和3460米，终止于尼斯组（Ness Formation）。33

/12-N-3 HHT2井在塔伯特组共钻遇153米，其中58米为储层质量中等的砂岩层。该井在尼斯组共钻遇162米，其中47米为储层性质中等至良好的砂岩层；在埃蒂夫组共钻遇26米，储层性质较差至中等的砂岩层。塔伯特组含气，而尼斯组和埃蒂夫组含油/凝析油。该井钻遇总高度为240米的油气柱，未遇到油水界面。已采集数据，包括压力数据。

33/12-N-3 HH井因井眼不稳定，钻至垂直深度3275米后被封堵废弃。技术侧钻井33/12-3 HHT2分别钻至测量深度7846米和垂直深度3715米，终止于德雷克组地层。

井场水深137米，所有井均已永久封堵废弃。

Equinor and its partners have discovered oil and gas in the "Granat" prospect near Gullfaks, 190 kilometres northwest of Bergen.

Wildcat wells 33/12-N-3 HH and 33/12-N-3 GH were drilled in connection with drilling an oil development well on the Gullfaks Satellites (33/12-N-3 IH) in production licence 152.

The discovery was made in 33/12-N-3 HH in production licence 277, which was awarded in 2002 (North Sea Awards 2001). This is the first exploration well in this production licence. Wildcat well 33/12-N-3 GH, which had drilling targets in production licence 152, was dry. Production licence 152 was awarded in 1988, in the 12th licensing round on the Norwegian continental shelf (NCS).

Preliminary estimates place the "Granat" discovery between 0.2 and 0.6 million standard cubic metres (Sm3) of recoverable oil equivalent (o.e.). This corresponds to 1.3 - 3.8 million barrels of o.e.

The licensees 锟� Equinor (operator), Petoro and OMV 锟� are considering tying the discovery back to existing infrastructure in the Gullfaks area.

The wells were drilled from production licence 050 using the Askeladden rig.
Geological information
The objective of wellbore 33/12-3GH (N2A) was to prove hydrocarbons in reservoir rocks in the Tarbert Formation, with secondary targets in the Ness and Etive formations, all in the Brent Group from the Middle Jurassic.

The well encountered the Tarbert Formation in a total of 115 metres with 48 metres of sandstone layers with moderate to good reservoir properties and a total of 59 metres in the Ness Formation with 10 metres of sandstone layers with good reservoir properties. Both formations were aquiferous. Data was collected, including pressure data.

Wellbore 33/12-3-GH was drilled to respective measured and vertical depths of 6708 and 3460 metres, and was terminated in the Ness Formation.

Wellbore 33/12-N-3 HHT2 encountered a total of 153 metres in the Tarbert Formation with 58 metres of sandstone layers with moderate reservoir quality. The wellbore encountered a total of 162 metres in the Ness Formation with 47 metres of sandstone layers with moderate to good reservoir properties, and a total of 26 metres of sandstone layers in the Etive Formation with poor to moderate reservoir properties. The Tarbert Formation contained gas, while the Ness and Etive formations were filled with oil/condensate. The well encountered a hydrocarbon column totalling 240 metres. The oil/water contact was not encountered. Data was collected, including pressure data.

Wellbore 33/12-N-3 HH was plugged and abandoned after being drilled to a vertical depth of 3275 metres due to an unstable hole. Technical sidetrack 33/12-3 HHT2 was drilled to respective measured and vertical depths of 7846 and 3715 metres, and was terminated in the Drake Formation.

Water depth at the site is 137 metres, and the wells have been permanently plugged and abandoned.
