HOUSTON, June 28 -- Statoil and two partners, after having drilled six exploratory wells on Block 30/11 south of Oseberg South field off Norway without commercial success, have proved a column of good-quality reservoir rock about 200 m thick.
Data are still being gathered at the Krafla exploratory well, but results so far clearly indicate that it is an oil discovery with 12.5 to 56.5 million bbl of oil equivalent recoverable and several follow-up opportunities, Statoil said. Krafla is Statoil's first operated well on the license.
The 30/11-8 S Krafla well went to 3,822 m true vertical depth below sea level in the Lower Jurassic Dunlin Group in 107.5 m of water in PL035. It proved hydrocarbons in the primary target Middle Jurassic Brent Group.
When Krafla is complete, the Ocean Vanguard semisubmersible will spud a planned sidetrack called Krafla West, also a Brent Group target. Krafla, 26 km south of Oseberg South, could be placed on production quickly and help extend the lift of existing installations. It likely will be tied back to a subsea installation in the Oseberg area.
Licensees in PL035/PL272 are Statoil operator with 50% interest and DNO ASA and Svenska Petroleum Exploration AS, 25% each.
Krafla is 16 km from the Katla prospect, proven in 2009, for which Statoil recently submitted a plan for development and production.
