The Toppand East well in the North Sea offshore Norway, drilled by Wellesley, Equinor and Petoro, has been proven dry.

The well, 35/11-29S, located in production licence 248 C, has been permanently plugged and abandoned after it proved be dry.

The license operator is Equinor, with 30% share, with partners Wellesley Petroleum and Petoro holding 40% and 30% stakes respectively.

The well was drilled with COSL’s COSLPromoter, a semi-submersible drilling rig designed to operate in water depths up to 750 meters.

PL 248 C was carved out of production licence 248 in 2013, and the area also covers the Swisher discovery, 35/11-24S A and B.

Development of Swisher is being viewed in context with Equinor’s Ringvei vest project, which is examining the possibility of linking a number of discoveries made in the area in recent years.
