Drilling Activity Summary
Description
Aker BP completed wildcat well #6607/12-4 and appraisal well #6607/12-4 A in the Norwegian North Sea. The wells were drilled about 7 km northeast of the Alve Nord gas and oil discovery. The exploration target for #6607/12-4 was to prove petroleum in reservoir rocks from the Jurassic/Triassic Age (Garn; Ile; Tofte; Tilje and Are). The secondary exploration target was to prove petroleum in reservoir rocks from Early Cretaceous (Lange). The #6607/12-4 as drilled to 3,109 m. In the primary exploration target, the well hit a gas column of 80 m in Garn, Not and Ile, 45 m of which is in sandstone layers with poor reservoir quality. In the other formations from Jurassic/Triassic, the sandstone layers are aquiferous with moderate to poor reservoir quality. In the secondary exploration target, the well encountered oil in three reservoir zones in Lange. In the upper zone, oil was encountered in a 2-m sandstone layer with poor to moderate reservoir quality, in the middle zone in a 5-m sandstone layer with moderate to good reservoir quality and in the lower zone in a 3-m sandstone layer with poor to moderate reservoir quality. No oil/water contacts were encountered. The primary exploration target for well #6607/12-4 A was to delineate a potential discovery in Jurassic/Triassic reservoir rocks. Preliminary estimates of the size of the gas/oil discovery in the Jurassic/Triassic are 17.6-35 MMbbl of oil equivalent. The oil discovery proven in the Lower Cretaceous is between 35-953 MMbbl of oil equivalent. The #6607/12-4 drilled to 4,124 m and was terminated in Are (Triassic), while #6607/12-4 A was terminated in Lange (Early Cretaceous). The wells are the first exploration wells in production license PL 127 C. Water depth at the site is 362 m. The wells have now been permanently plugged and abandoned. Aker is based in Oslo.
