Wellesley’s exploration success has given us an industry leading portfolio of low CO2 Norwegian development projects. In 7 years, Wellesley has drilled 27 wells, 8 as operator, with 9 commercial discoveries.

Wellesley drilled its first operated well in 2017, two years after the company was established, and will drill its first operated HP/HT well in 2023.


Enabling the world’s transition to cleaner forms of energy requires a secure supply of low CO2 oil and gas.

Wellesley works to meet this demand with as little impact on the environment as possible. This requires a continued and diligent effort to achieve our ESG goals. Goals which have been set to lower the carbon footprint at every level of our organisation.
