Lundin Energy AB announced that it has completed exploration well 7221/4-1, targeting the Polmak prospect in licences PL609 and PL1027, in the southern Barents Sea. The well was dry.
The main objective of the well was to prove hydrocarbons in Triassic aged sandstones within the Kobbe formation of the Polmak prospect. The well encountered indications of hydrocarbons in a 9 meter interval in poor quality reservoir in the targeted formation and the well was classified as dry.
The well was drilled 30 km east of the Johan Castberg discovery, by the West Bollsta semi-submersible drilling rig. Lundin Energy is the operator of Polmak with a 47.5 percent working interest (contingent on the completion of the previously announced acquisition of certain interests from Idemitsu Petroleum Norge AS). The partners are Wintershall DEA Norge AS with 25 percent, INPEX Norge AS with 10 percent, DNO Norge AS with 10 percent and Idemitsu Petroleum Norge AS with 7.5 percent working interests.
Located on the Loppa High, the Polmak well is about 8 km to the east of the 7220/6-2 Neiden discovery made in 2016, also by Lundin. This well encountered a total oil column of about 20 meters with an overlying gas column of about 10 meters in carbonate rocks of the Permo-Carboniferous Ørn Formation, with good to moderate reservoir properties.
In the Triassic Snadd Formation, 7220/6-2 encountered a water-bearing sandstone with moderate to good reservoir properties. Estimates of the size of the discovery were between 3 and 7 million cubic meters of recoverable oil and between 1 and 2 billion cubic meters of recoverable gas (59 million barrels of oil equivalent at most).
The West Bollsta rig will now proceed to drill the Lundin Energy operated (40 percent working interest), Bask prospect in PL533B. Well 7219/11-1 will target Paleocene aged sandstones, estimated to hold gross unrisked prospective resources of 250 MMbo. The partners are Aker BP with 35 percent and Wintershall DEA with 25 percent working interests.
