據離岸能源4月21日消息，挪威能源巨頭挪國油Equinor及其合作伙伴道達爾(Total)和V?r Energi在挪威海Tyrihans油田的一個新區塊發現了石油和天然氣。這一發現將立即投入生產。

　　Equinor周三在一份聲明中稱，目前估計可采資源量在300 - 420萬標準立方米油當量之間，相當于1900 - 2600萬桶油當量。

　　Equinor挪威大陸架勘探高級副總裁尼克·阿什頓表示:“證明新資源可以延長挪威海油田的生產壽命，這是令人鼓舞的。”

　　勘探井6407/1-A-3 BH位于生產許可證073處，使用Transocean Norge鉆井平臺在Tyrihans North的海底模板A上鉆井。

　　Tyrihans油田位于挪威海中部，距離?sgard油田東南約25公里，距離特隆赫姆西北約220公里。

　　與挪威海Halten Bank地區Kristin和?sgard油田的現有設施和基礎設施相結合，使其成為一個完整的海底解決方案。

　　據Equinor表示，被許可方認為該發現具有商業價值，并打算立即開始生產。

　　阿什頓稱:“由于位置優越，我們能夠立即將Tyrihans油田的發現投入生產，這將確保良好的盈利能力和生產過程中的低碳排放。”

　　該井旨在探明中下侏羅統儲層(Ile和Tilje組)中的石油。

　　Equinor表示，該井在Ile地層中發現了一個約43米的氣柱和一個約15米的油柱，其中包括約76米的中等至優質砂巖儲層。在Tilje組中，發現了中優質含水儲層。

　　該井未經過地層測試，但進行了數據采集和取樣。這是Tyrihans油田鉆探的第六口勘探井，也是1982年第5輪許可證授予的73號生產許可證鉆探的第五口勘探井。

　　Equinor還指出，該井的垂直深度為海平面以下3998米，實測深度為5332米。

　　該井在288米深的下侏羅統?re地層完井。這個試點項目將被永久地堵塞并廢棄。

　　Transocean Norge鉆井平臺將繼續在Tyrihans油田生產井6407/1-A-3 CH鉆井。

　　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.
