Statoil ASA and partners have completed an appraisal well in the western part of the Johan Sverdrup field in the Norwegian sector of the North Sea. The well found a gross 269-foot oil column in Jurassic sandstones and during a production test, flowed at a rate of 6,000 barrels per day in the upper part of the reservoir.
"Well results confirm the extent of the reservoir along the western margin of the field and excellent reservoir characteristics we have seen elsewhere in the Johan Sverdrup field. This is important input for the further planning of the field development," said Øivind Reinertsen, senior vice president for Johan Sverdrup field development, in a press release.
Drilled by the Ocean Vanguard (mid-water semisub), the 16/2-17s appraisal well and a subsequent sidetrack 16/2-17B tested the potential in the Cliffhanger South prospect located in an area west of the Johan Sverdrup field.
"The appraisal well removes any uncertainty related to the fields’ extension along the western fault, said Vice President of Det norske Oljeselskap, Odd Ragnar Heum, in a released statement.
"The fact that the reservoir shows the same exceptional qualities is very positive. We are happy to have completed the appraisal program in the central part of the field, and are now ready to place the field center and start working on the development concept."
The sidetrack did not encounter the expectant reservoir so Cliffhanger South is considered dry. The consortium was targeting a separate target in Production License 265 and the outcome of the sidetrack does not change volume estimates for Johan Sverdrup, stated Statoil.
The consortium plans to drill Cliffhanger North this August.
Appraisal well 16/2-17S was drilled approximately .9 miles south west of appraisal well 16/2-8 in PL265 and 1.49 miles north west of appraisal well 16/2-11 in PL501.
Johan Sverdrup will be developed with several platforms in the North Sea.
Statoil operates the consortium with a 40 percent stake while Petoro holds 30 percent, Det norske Oljeselskap with 20 percent and Lundin Norway AS with 10 percent.
