Statoil Petroleum AS, operator of production licence 230, has completed drilling of wildcat well 7227/10-1, in the Barents Sea.
Statoil was granted a drilling permit for well 7227/10-1 from the Norwegian Petroleum Directorate (NPD) in October, 2014. The name of the prospect is “Saturn”.
The well was drilled about 30 kilometres southwest of the 7228/7-1 oil and gas discovery and about 210 kilometres northeast of Hammerfest.
The primary exploration target for the well was proving petroleum in Late Triassic reservoir rocks (Snadd formation). The secondary exploration target was proving petroleum in Middle Triassic reservoir rocks (Kobbe formation), as well as investigating the presence and quality of Early to Middle Triassic source rock.
The well encountered about 40-metre thick reservoir rocks in the Snadd formation and about 15-metre thick reservoir rocks in the Kobbe formation, both with poor reservoir quality. The well is dry.
Data acquisition and sampling were carried out.This is the first exploration well in production licence 230, which was awarded in the Barents Sea project in 1997.
The well was drilled to a vertical depth of 3095 metres below the sea surface, and was terminated in the Kobbe formation. Water depth is 232 metres. The well will now be permanently plugged and abandoned.
Well 7227/10-1 was drilled by the Transocean Spitsbergen semi-submersible drilling rig, which will now proceed to wildcat well 7324/9-1 in the Barents Sea to cut and pull the wellhead. The well is located in production licence 614, where Statoil Petroleum AS is the operator.
