  • Exploration & Production

Norwegian oil and gas company Aker BP has completed the drilling of wildcat well 15/6-16 S, which is located in the central part of the North Sea off Norway. The well is dry. 

The Norwegian Petroleum Directorate (NPD) said on Thursday that well was drilled about 10 kilometers north of the Gina Krog field and 220 kilometers west of Stavanger. The well is located in production license 777 where Aker BP is the operator. The well was named Hornet Main.

The 15/6-16 S wildcat was drilled by the Deepsea Stavanger drilling rig. Aker BP received consent from the Petroleum Safety Authority (PSA) to drill the 15/6-16 S well using the Deepsea Stavanger rig in May 2019.

The primary exploration target for well 15/6-16 S was to prove petroleum in reservoir rocks from the Middle Jurassic Age (the Hugin and Sleipner formation). The secondary exploration target was to prove petroleum in reservoir rocks from the Late Triassic Age (the Skagerrak formation).

The well 15/6-16 S encountered the Hugin formation with a thickness of about 10 metres, of which sandstone layers totaling 5 meters with poor reservoir quality. The Sleipner formation of 95 meters has sandstone layers totaling 25 meters with reservoir properties of moderate to poor quality.

The Skagerrak formation came in with a thickness of 80 meters, with sandstone layers totaling 25 meters with poor to moderate reservoir quality. The well is dry. Data acquisition and sampling have been carried out.

This is the first exploration well in production license 777, which was awarded in APA 2015.

The well was drilled to respective vertical and measured depths below the sea surface of 4162 and 4173 meters, and was terminated in the Skagerrak Formation from the Late Triassic Age.

Water depth at the site is 116 meters. The well will now be permanently plugged and abandoned.

The Deepsea Stavanger drilling rig will now proceed to production license 442 in the central part of the North Sea to drill wildcat well 25/2-20, where Aker BP is also the operator.

Aker BP has already secured a drilling permit and a safety consent to use the Deepsea Stavanger for the 25/2-20 wildcat well.
