据离岸能源4月21日消息，挪威能源巨头挪国油Equinor及其合作伙伴道达尔(Total)和V?r Energi在挪威海Tyrihans油田的一个新区块发现了石油和天然气。这一发现将立即投入生产。
Equinor周三在一份声明中称，目前估计可采资源量在300 - 420万标准立方米油当量之间，相当于1900 - 2600万桶油当量。
Equinor挪威大陆架勘探高级副总裁尼克·阿什顿表示:“证明新资源可以延长挪威海油田的生产寿命，这是令人鼓舞的。”
勘探井6407/1-A-3 BH位于生产许可证073处，使用Transocean Norge钻井平台在Tyrihans North的海底模板A上钻井。
Tyrihans油田位于挪威海中部，距离?sgard油田东南约25公里，距离特隆赫姆西北约220公里。
与挪威海Halten Bank地区Kristin和?sgard油田的现有设施和基础设施相结合，使其成为一个完整的海底解决方案。
据Equinor表示，被许可方认为该发现具有商业价值，并打算立即开始生产。
阿什顿称:“由于位置优越，我们能够立即将Tyrihans油田的发现投入生产，这将确保良好的盈利能力和生产过程中的低碳排放。”
该井旨在探明中下侏罗统储层(Ile和Tilje组)中的石油。
Equinor表示，该井在Ile地层中发现了一个约43米的气柱和一个约15米的油柱，其中包括约76米的中等至优质砂岩储层。在Tilje组中，发现了中优质含水储层。
该井未经过地层测试，但进行了数据采集和取样。这是Tyrihans油田钻探的第六口勘探井，也是1982年第5轮许可证授予的73号生产许可证钻探的第五口勘探井。
Equinor还指出，该井的垂直深度为海平面以下3998米，实测深度为5332米。
该井在288米深的下侏罗统?re地层完井。这个试点项目将被永久地堵塞并废弃。
Transocean Norge钻井平台将继续在Tyrihans油田生产井6407/1-A-3 CH钻井。

Equinor to put new oil & gas find on stream immediately
Norwegian energy giant Equinor and partners Total and V?r Energi have struck oil and gas in a new segment belonging to the Tyrihans field in the Norwegian Sea. The discovery will be put on stream immediately.
Recoverable resources are so far estimated at between 3.0 and 4.2 million standard cubic metres of recoverable oil equivalent, corresponding to 19 – 26 million barrels of oil equivalent, Equinor said in a statement on Wednesday.
“It is encouraging to prove new resources that can extend the life of producing fields in the Norwegian Sea”, said Nick Ashton, Equinor’s senior vice president for exploration on the Norwegian continental shelf.
The exploration well 6407/1-A-3 BH in production licence 073 was drilled from subsea template A at Tyrihans North using the Transocean Norge drilling rig.
The Tyrihans field is located in the middle of the Norwegian Sea, some 25 kilometres southeast of the ?sgard field and 220 kilometres northwest of Trondheim.
It is a complete subsea solution tied back to existing installations and infrastructure on the Kristin and ?sgard fields in the Halten Bank area of the Norwegian Sea.
According to Equinor, the licensees consider the discovery commercial and intend to start production immediately.
“Thanks to the location we are able to put the discovery on stream over the Tyrihans field immediately, which will both ensure good profitability and low CO2 emissions from production”, said Ashton.
The purpose of the well was to prove petroleum in lower-mid Jurassic reservoir rocks (Ile and Tilje formations).
Equinor said that the well struck a gas column of about 43 metres and an oil column of about 15 metres in the Ile formation, including about 76 metres of moderate to good reservoir quality sandstone. In the Tilje formation moderate to good quality water-bearing reservoir was struck.
The well was not formation tested, but data acquisition and sampling took place. This is the sixth exploration well drilled on the Tyrihans field, and the fifth exploration well drilled in production licence 73 awarded in the 5th licensing round in 1982.
Equinor also stated that the well was drilled to a vertical depth of 3998 metres below the sea level and a measured depth of 5332 metres.
The well was completed in the ?re formation from the lower Jurassic period in 288 metres of water. The pilot will be permanently plugged and abandoned.
The Transocean Norge drilling rig will now continue drilling the producer 6407/1-A-3 CH on the Tyrihans field.
