A joint venture led by Neptune Energy has made an oil and gas discovery within tie-back distance of the Gjoa platform offshore Norway.
The Hamlet exploration well in Block PL153 has an estimated in-place volume of between 30 million and 70 million barrels of oil equivalent, said Neptune.
Work is ongoing to confirm the potential recoverable resources, but Neptune’s preliminary estimate is between 8 million boe and 24 million boe.
Hamlet is located 58 kilometres west of Floro, Norway, at a water depth of 358 metres.
It will be considered as a tie-back to the Neptune-operated Gjoa production platform.
Neptune Energy’s managing director for Norway and the UK, Odin Estensen, said: “This discovery is in line with Neptune’s strategy to focus on exploration around existing hubs, enabling us to fast-track development, and to keep costs down and carbon emissions low.
“A potential field development would build on our experiences from recent successful developments of the Duva field and Gjoa P1 segment.”
The drilling programme comprised a main bore with a sidetrack. Both wells hit hydrocarbons, and the sidetrack confirmed an oil-water contact.
Neptune added the discovery confirmed the extended potential of the Agat play, previously only developed and produced in the Duva field, and the operator plans to drill the Ofelia exploration well in the same play later this year.
Hamlet was drilled using the semi-submersible rig Deepsea Yantai, owned by CIMC and operated by Odfjell Drilling.
Neptune holds a 30% stake in the joint venture, with Petoro also holding 30%, Wintershall Dea holding 28% and and Okea 12%.
