Upon entering the reservoir, logs and cuttings have identified hydrocarbons and a decision has been made to initiate coring.
The operations in the reservoir section are still at an early stage and final results are not yet available. A contingent side-track may be drilled to further define the extent of the discovery.
Dugong is located 158 km west of Florø, Norway, at a water depth of 330 m, and is close to the existing production facilities of the Snorre field. The reservoir lies at a depth of 3250 - 3400 m.
The drilling programme, which began on 18 June, comprises a main bore with a down-dip side track, subject to the results of the main bore.
Dugong has been drilled by the Deepsea Yantai (pictured), a new semi-submersible rig, owned by CIMC and operated by Odfjell Drilling.
Neptune holds a 40% in the licence, with Petrolia NOCO, Concedo, and Idemitsu Petroleum each holding 20% interests.
