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 m 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 47.51% working interest. The partners are Wintershall DEA Norge AS with 25%, INPEX Norge AS with 10%, DNO Norge AS with 10% and Idemitsu Petroleum Norge AS with 7.5% working interests.
The West Bollsta rig will now proceed to drill the Lundin Energy operated (40% working interest), Bask prospect in PL533B. Well 7219/11-1 will target Paleocene aged sandstones, estimated to hold gross unrisked prospective resources of 250 million boe. The partners are Aker BP with 35% and Wintershall DEA with 25% working interests.
