Equinor在北海发现天然气和凝析油

据OE网站7月8日报道，挪威油气公司Equinor在位于挪威近海的北海亚特兰蒂斯30/2-5S号探井中发现了天然气和凝析油。

该发现是在北海Kvitebj?rn油田以南约17公里，卑尔根西北160公里处发现的。

根据初步估计，探明储量在300万-1000万标准立方米的可采石油当量，相当于1900万-6300万桶石油当量。

Equinor负责挪威和英国勘探的高级副总裁尼克?阿什顿（Nick Ashton）表示，看到我们能够在挪威大陆架最成熟的区域之一继续探明更多资源，这是令人鼓舞的。现在，我们将致力于评估盈利和二氧化碳高效回收的潜力。

30/2-5 S探井的主要勘探目的是探明Brent组中侏罗系储层的油气。该井遇到了160米高的气柱，其中60米代表了有效的中侏罗世储层岩石。Ness、Etive、Tarbert组储层质量欠佳，Rannoch组储层质量较差。

虽然没有对该井进行地层测试，但是已经获得了大量的数据并采集了样本。这口井钻探到海平面以下4359米的垂直深度。该地区的水深为142米。这口井被永久地堵住并废弃了。

这是生产许可区878中要钻的首个勘探井。 该许可证在2016年预定地区授予(APA2016)中获得。 该许可持有单位会在整体评估该地区时，考虑是否继续进行有关发现。

该井是由西赫拉克勒斯（West Hercules）钻机钻探的，该钻机正继续在生产许可区248 C钻探35 / 11-24 S勘探井，这是一个名为Swisher的勘探区。

生产许可区878的所有者是Equinor Energy(60%)、Source Energy(20%)和Wellesley Petroleum(20%)。

Equinor Finds Gas and Condensate at Atlantis Well in North Sea

Norwegian oil and gas company Equinor has discovered gas and condensate in the exploration well 30/2-5 S Atlantis, in the North Sea, offshore Norway.

The discovery was made about 17 kilometers south of the Kvitebj?rn field in the North Sea and 160 kilometers northwest of Bergen.

Based on preliminary estimates the proven reserves are between 3 and 10 million standard cubic meters of recoverable oil equivalent, corresponding to 19-63 million barrels of oil equivalent.

Nick Ashton, Equinor’s senior vice president for exploration in Norway and the UK: “It is encouraging to see that we are able to keep proving more resources in one of the most mature areas on the Norwegian continental shelf. Now we will work on evaluating the potential for profitable and CO2 efficient recovery.

The primary exploration target of exploration well 30/2-5 S was to prove hydrocarbons in the Middle Jurassic reservoir of the Brent Group. The well encountered about a 160-meter high gas column, of which 60 meters represent an effective Middle Jurassic reservoir rock. Poor to satisfactory reservoir quality was encountered in the Ness, Etive, and Tarbert formation, while the Rannoch formation had poor reservoir quality.

The well was not formation tested however extensive amounts of data have been acquired and samples have been taken. The well was drilled to a vertical depth of 4359 meters below sea level. Water depth in the area is 142 meters. The well was permanently plugged and abandoned.

This is the first exploration well to be drilled in production license 878. The license was awarded in the Awards in Predefined Areas 2016 (APA 2016). The licence owners will consider whether to pursue the discovery in an overall assessment of the area.

The well was drilled by the West Hercules drilling rig, which is moving on to drill the exploration well 35/11-24 S, a prospect named Swisher, in production license 248 C.

The license owners of production license 878 are Equinor Energy AS (60%), Source Energy (20%), and Wellesley Petroleum AS (20%).
