Wellesley Petroleum drills dry well north of Gjøa field

The well was drilled about 65 km northwest of Florø and about 60 km north of Gjøafeltet in the northern part of the North Sea.

The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks in the Krossfjord Formation.

The well encountered the Krossfjord Formation with water-bearing sandstone rocks at about 33 m, with poor to moderate reservoir quality. Water-bearing sandstone rocks were also encountered at about 33 m with poor to moderate reservoir quality, of unknown age, deeper in the well. The Krossfjord Formation has traces of petroleum. The well has been classified as dry.

Data acquisition has been carried out. This is the second exploration well in production licence 885, which was awarded in APA 2016. Well 36/1-4 S was drilled to a vertical depth of 3224 m below sea level and was terminated in basement rock.

Water depth at the site is 211 m. The well will be permanently plugged and abandoned.

Well 36/1-4 S was drilled by the Borgland Dolphin drilling facility (pictured), which will now proceed to Fedafjorden.
