挪国油在北海Vigdis油田附近发现石油

据油田技术7月14日报道，Equinor已经完成了在北海北部Vigdis Vest油田西北部的Wildcat井34/7-E-4 AH的钻探。

这口井的目的是证明中侏罗世储层岩石中的石油（Rannoch地层）。

34/7-E-4AH井在Rannoch组遇到约20m的油柱，其中18m为储层质量较好的砂岩。在2479m深处发现了油/水接触。

初步计算发现的规模在90万至150万立方米之间。到目前为止，这一发现被认为是商业性的，并将被考虑与Vigdis油田相结合。

该井未进行地层测试，但进行了数据采集和采样。这是089号生产许可证中的第41口探井。生产许可证089于1984年在第八轮发牌中获颁。

34/7-E-4 AH井从Vigdis油田的现有开发井34/7-E-4 H作为浅侧钻探，垂直深度低于海平面2517 m，测量深度为4459 m。

Equinor makes minor oil discovery near Vigdis field in the North Sea

Equinor has completed the drilling of wildcat well 34/7-E-4 AH just northwest of the Vigdis Vest field in the northern part of the North Sea and 160 km west of Flor?.

The objective of the well was to prove petroleum in reservoir rocks from the Middle Jurassic Age (the Rannoch Formation).

Well 34/7-E-4 AH encountered an oil column of about 20 m in the Rannoch Formation, 18 m of which are sandstone of good reservoir quality. The oil/water contact was encountered at a depth of 2479 m.

The preliminary calculation of the size of the discovery is between 0.9 and 1.5 million m3 of recoverable oil. So far, the discovery is presumed to be commercial and will be considered for tie-in to the Vigdis field.

The well was not formation-tested, but data acquisition and sampling were carried out.

This is the 41st exploration well in production licence 089. Production licence 089 was awarded in 1984 in the 8th licensing round.

Well 34/7-E-4 AH was drilled as a shallow sidetrack from existing development well 34/7-E-4 H on the Vigdis field, to a vertical depth of 2517 m below sea level and a measured depth of 4459 m.
