Wellesley Petroleum AS is a Norwegian oil and gas exploration and development company focused exclusively on the Norwegian Continental Shelf. Founded in 2015 and headquartered in Stavanger, the company acts as both a licensee and an exploration operator, targeting low-emission oil and gas resources suitable for development as tie-backs to existing infrastructure.
Since its establishment, Wellesley has drilled more than 30 wells, including 11 as operator, resulting in 10 commercial discoveries. Its portfolio features high-pressure high-temperature (HPHT) projects such as Afrodite (5% interest in PL293 alongside Equinor as operator and ORLEN), Atlantis, Carmen, and others. The company prioritizes gas-intensive assets with electrification potential and emphasizes ESG goals to minimize carbon footprint while supplying secure hydrocarbons to Europe.
Backed by private equity firm Blue Water Energy via Wellesley Holdco Ltd., Wellesley has secured multiple APA license awards, completed farm-ins, and executed asset transactions. It has established itself as one of Norway's more active explorers, contributing to the development of unconventional resources on the NCS and supporting the energy transition through cleaner production methods.
