Wellesley will drill 3 wells in the next 2 years, targeting an unrisked net resource of 51 mmboe.

Wellesley’s exploration strategy is aligned with the core ESG strategic themes of “Power From Shore Oil” and “Gas to Europe”. Any discoveries in the “Power From Shore Oil” theme will be developed as part of the FANTA area development, together with Wellesley’s Grosbeak, Swisher and Toppand discoveries.

Why Norway

Norway’s rich reserves of hydrocarbons, efficient tax terms, robust infrastructure and leading safety and environmental standards, make it the perfect place to focus Wellesley’s operations.

The country has been an established petroleum province for fifty years and will continue to produce for another fifty. Norway’s pipeline gas provides security of supply to its European markets in a time of increasing demand and geopolitical uncertainty.
