Wellesley Petroleum fails to find hydrocarbons with 6204/11-3 well in PL 829

Wellesley Petroleum has failed to find any hydrocarbons following the drilling of exploratory well 6204/11-3 in production licence 829 (PL 829) in the Norwegian North Sea.

The wild cat well was spudded by the PL 829 operator nearly 75 kilometres north of the Gjøa field and 60 kilometres northwest of the Norwegian town of Florø.

The goal of the 6204/11-3 well was to prove petroleum in reservoir rocks in the Lower Cretaceous (the Åsgard Formation). However, it did not intersect reservoir rocks in the Åsgard Formation.

According to the Norwegian Petroleum Directorate (NPD), nearly 30 metres of aquiferous sandstone was met in underlying Jurassic rocks with moderate to very good reservoir quality.

The 6204/11-3 well has been declared as dry and was not formation-tested. However, data acquisition was performed.

It is the first exploration well in PL 829, which was awarded in APA 2015.

Norwegian Petroleum Directorate stated: “The 6204/11-3 was drilled to a vertical depth of 1290 metres below sea level and was terminated in basement rock.

“Water depth at the site is 211 metres. The well has now been permanently plugged and abandoned.”

The 6204/11-3 was drilled by the Borgland Dolphin drilling facility, which is now sailing to the Kvina Shipyard in Fedafjorden.
