Statoil spudded exploration well 30/11-14 Slemmestad in the North Sea last week, according to the Norwegian Petroleum Directorate.
The Slemmestad well is located in PL 272/PL 035 some 20km south of the Oseberg field and approximately 130km from the nearest land that is Sund municipality in Hordaland.
The main purpose of the exploration well 30/11-14 is to confirm the commercial resources in the Slemmestad prospect. The main reservoir in Slemmestad is sandstone from the Jurassic Age (Tarbert formation). If the results from the main well is not conclusive with respect to the hydrocarbon filling in the reservoir, the sidetrack 30/11-14 A Slemmestad sidetrack well will be drilled.
In addition, to confirm commercial resources in the nearby Haraldsplass prospect, another sidetrack, 30/11-14 B, will be drilled. The main reservoir in the 30/11-14 B is sandstone from the Jurassic Age (Tarbert formation).
The well is being drilled with semisubmersible rig Songa Delta. Drilling is expected to take 104 days: 57 days for the main well, 17 days for sidetrack 30/11-14 A and 30 days of sidetrack 30/11-14 B.
Statoil is the operator in PL 272/PL 035 with 50% stake, with 50% partner Det norske.
