Neptune Energy and its partners have announced the discovery of oil and gas at the Hamlet exploration wells PL153 in the Norwegian sector of the North Sea. In-place volumes discovered in the Hamlet structure are estimated to be in the range of 5-11 million standard cubic metres (MSm3) or 30-70 million barrels of oil equivalent (mmboe). Work is continuing to confirm potential recoverable resources, but Neptune’s preliminary estimate is 8-24 mmboe.Hamlet was drilled by the Deepsea Yantai, a semi-submersible rig, owned by CIMC and operated by Odfjell Drilling. The drilling program comprised a main-bore (35/9-16S) with a side-track (35/9-16A). Both wells found hydrocarbons, and the sidetrack confirmed an oil/water contact at 2662 metres total vertical depth. Neptune and its partners have initiated studies to consider development options for the discovery.Located 58 kilometres west of Florø, Norway, at a water depth of 358 metres, Hamlet will be considered as a tie-back to the Neptune-operated Gjøa semi-submersible platform.Hamlet is a new discovery in the Gjøa area, where Neptune already operates two fields. The Wintershall Dea-operated fields Vega and Nova are also tied back to the Gjøa platform.Hamlet-partners: Neptune Energy (operator and 30%), Petoro (30%), Wintershall Dea (28%), OKEA (12%).
