14/06/2024 The ”Toppand east” well 35/11-29 S in the North Sea, drilled by Wellesley, Equinor and Petoro, proved to be dry.

The well is located in production licence 248 C, where Equinor is the operator. Wellesley Petroleum was the operator for this well, which was drilled using the COSL Promoter rig. PL 248 C was carved out of production licence 248 in 2013. The area also covers the “Swisher” discovery (35/11-24S A and B).

PL 248 C is working to identify additional resources to the "Swisher" discovery to make a development more robust as part of Equinor's Ring Road West project.

Geological info

The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks in the Brent Group and the Oseberg Formation.

The well encountered the Ness Formation with a total thickness of around 64 metres with an 18-metre sandstone reservoir with poor reservoir quality, the Etive Formation with a total thickness of around 51 metres with a 26-metre sandstone reservoir with good reservoir quality, as well as the Oseberg Formation with a total thickness of around 50 metres with a 50-metre sandstone reservoir with moderate reservoir quality.

The well is dry.

Well 35/11-29 S was drilled to respective vertical and measured depths of 3490 metres and 3575 metres below sea level, and was terminated in the Cook Formation in the Lower Jurassic.

Water depth at the site is 355 metres. The well has been permanently plugged and abandoned.
