Wellbore history
GeneralWell 7219/9-2 was drilled on the boundary between Bjørnøyrenna Fault Complex and Polhem Sub-platform in the Barents Sea. The target was Cretaceous syn-rift sand bodies. The Kolmule Formation was primary objective (Kayak prospect) and the Knurr Formation was secondary objective (Husky prospect).Operations and resultsWildcat well 7219/9-2 was spudded with the semi-submersible installation Songa Enabler on 5 June 2017 and drilled to TD at 2568 m (2564.5 m TVD) m in the Middle Jurassic Stø Formation. Operations proceeded without significant problems. The well was drilled with Seawater and hi-vis pills down to 888.6 m and with Enviromul oil-based mud from 888.6 m to TD.Sandstones in the lower part of the Kolmule Formation (Kayak prospect), was encountered at 1536 m (1536 m TVD). The reservoir consists of two sandstone intervals of moderate to poor reservoir quality. The reservoir was oil-bearing in the upper sand with an oil-down-to contact at 1568 m. The lower sand was water-bearing, but had oil shows in the form of direct and cut fluorescence throughout down to 1700 m. The deeper Knurr Formation (Husky prospect) was penetrated at 2027 m. Sand bodies were present also here, but this reservoir was water filled without shows.Two cores were cut from 1548.8 to 1701.1 m with close to 100% total recovery. MDT fluid samples were taken at 1555.4 m (oil), 1543.9 m (oil), 1563.6 m, and 1672.0 m (oil).The well was permanently abandoned on 2 July 2017 as an oil discovery.TestingNo drill stem test was performed. -
