Equinor公司在巴伦支海的Johan Castberg油田发现了新的石油储量，该储量将与Johan Castberg油田相连。此次发现位于“Olynya Tubën”勘探区（7220/7-5井）。该井由中海油探矿者号钻井平台钻探。初步估计可采储量为1400万至2400万桶油当量。

Johan Castberg 油田的产量基数最初估计为 5 亿至 7 亿桶，Equinor 的目标是再增加 2 亿至 5 亿桶。

2025 年 6 月，卡斯特贝格地区发现了一个名为“Drivis Tubblocken”的石油发现，估计 Drivis 构造的储量为 13-2000 万桶。

上周，Isflak油田开发工程正式开工，这是首个与Johan Castberg油田相连的油田。位于桑内斯耶芬的Aker Solutions公司正在建造井架，用于钻探两口新井，这两口井将与现有的海底设施相连。

Equinor made an oil discovery that will be tied into the Johan Castberg field in the Barents Sea. The discovery was made in the “Polynya Tubåen” prospect (7220/7-5). The well was drilled by the COSL Prospector rig. The preliminary volume estimate is between 14 and 24 million barrels of recoverable oil equivalents.

The volume basis in Johan Castberg was originally estimated at 500–700 million barrels, and Equinor has an ambition to increase this by an additional 200–500 million barrels.

In June 2025, an oil discovery called “Drivis Tubåen” was made in the Castberg area, estimated at 13–20 million barrels in the Drivis structure.

Last week marked the start of construction for the development of Isflak, the first discovery to be tied into Johan Castberg. Aker Solutions in Sandnessjøen is building a well frame for two new wells that will be connected to existing subsea facilities.
