據(jù)油田技術(shù)7月14日?qǐng)?bào)道，Equinor已經(jīng)完成了在北海北部Vigdis Vest油田西北部的Wildcat井34/7-E-4 AH的鉆探。

這口井的目的是證明中侏羅世儲(chǔ)層巖石中的石油（Rannoch地層）。

34/7-E-4AH井在Rannoch組遇到約20m的油柱，其中18m為儲(chǔ)層質(zhì)量較好的砂巖。在2479m深處發(fā)現(xiàn)了油/水接觸。

初步計(jì)算發(fā)現(xiàn)的規(guī)模在90萬(wàn)至150萬(wàn)立方米之間。到目前為止，這一發(fā)現(xiàn)被認(rèn)為是商業(yè)性的，并將被考慮與Vigdis油田相結(jié)合。

該井未進(jìn)行地層測(cè)試，但進(jìn)行了數(shù)據(jù)采集和采樣。這是089號(hào)生產(chǎn)許可證中的第41口探井。生產(chǎn)許可證089于1984年在第八輪發(fā)牌中獲頒。

34/7-E-4 AH井從Vigdis油田的現(xiàn)有開(kāi)發(fā)井34/7-E-4 H作為淺側(cè)鉆探，垂直深度低于海平面2517 m，測(cè)量深度為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.
