Suncor Energy wraps up appraisal well drilling in North Sea

Suncor Energy Norge AS, operator of production licence 375, has completed drilling of appraisal well 34/4-14 S in the oil discovery 34/4-11, in the North Sea.

The discovery was proven in 2010, and is located approximately 20 kilometres northwest of the Snorre field in the North Sea.

The reservoir is in the Brent and Statfjord groups and, prior to drilling of appraisal well 34/4-14 S, the expected recoverable reserves were about 7 million Sm3 of oil and 0.7 billion Sm3 of gas.

According to the Norwegian Petroleum Directorate (NPD), the purpose of well 34/4-14 S was to delineate the discovery proven with well 34/4-11 and delineated by well 34/4-13 S. The well encountered a reservoir in the Statfjord group from the Early Jurassic Age and proved 11 metres of net sandstone of good quality. The well is dry.

Data acquisition and sampling has been carried out. This well is the third exploration well in production licence 375, awarded in APA 2005.

The well was drilled to a vertical depth of 4532 metres below the sea surface and was terminated in the Lunde formation from the Late Triassic Age. The NPD says that the well will be permanently plugged and abandoned.

Well 34/4-14 S was drilled by the Borgland Dolphin semi-submersible drilling rig, which is now scheduled to drill wildcat well 25/10-13 S in production licence 571, operated by Suncor Energy AS.
