Neptune Energy has initiated studies to consider development options for Hamlet (PL153) in the Norwegian sector of the North Sea following confirmation of an oil and gas discovery and the extended potential of the Agat play.
A further exploration well (Ofelia prospect) at Agat—previously only developed and produced in Neptune-operated Duva field—will be drilled later this year, said Steinar Meland, Neptune’s director of exploration and development in Norway, in a release Apr. 28.
At the Hamlet structure, In-place volumes are estimated to be 5-11 million standard cu m (30-70 MMboe). Work is continuing to confirm potential recoverable resources, but Neptune’s preliminary estimate is 8-24 MMboe.
Hamlet lies 58 km west of Florø, Norway, at a water depth of 358 m. It will be considered as a tie-back to the Neptune-operated Gjøa semisubmersible platform.
Hamlet is a new discovery in the Gjøa area, where Neptune operates two fields. Wintershall Dea-operated Vega and Nova fields are also tied back to Gjøa platform.
The drilling program comprised a main-bore (35/9-16S) with a sidetrack (35/9-16A) (OGJ Online, Mar. 21, 2022; Apr. 8, 2022). Both wells found hydrocarbons, and the sidetrack confirmed an oil-water contact at 2,662 m total vertical depth.
Hamlet was drilled by the Deepsea Yantai, a semisubmersible rig, owned by CIMC and operated by Odfjell Drilling.
Neptune is operator at Hamlet with 30% interest. Partners are Petoro 30%, Wintershall Dea 28%, and OKEA 12%.
