Neptune Energy Norge AS encountered hydrocarbons at the Hamlet exploration well in the Norwegian sector of the North Sea, 58 km west of Florø in production license (PL) 153.

The well was drilled by the semi-submersible Deepsea Yantai in 358 m of water targeting the Lower Cretaceous Agat formation (OGJ Online, Feb. 28, 2022). The drilling program comprised a main bore (35/9-16S) with an optional sidetrack (35/9-16A) based on the outcome of the well.

Logs encountered hydrocarbons and a decision was made to initiate coring. Operations in the reservoir section are at an early stage. It has yet to be confirmed if commercial volumes are present.

Hamlet is 7 km north of Gjøa field. In the event of a commercial discovery, the prospect could be tied back to the Neptune-operated Gjøa platform and produced with less than half the average CO2 emissions on the Norwegian Continental Shelf, the company said.

Neptune is operator of the license with 30% interest. Partners are Petoro AS (30%), Wintershall Dea Norge AS (28%), and OKEA ASA (12%).
