Statoil, operator of production licence 104, has completed drilling of wildcat well 30/9-28 S, located about 5.5 kilometres west of the Oseberg South field in the central part of the North Sea and 140 kilometres west of Bergen.
The well encountered an approx. 20-metre gas column, of which 10 metres were in sandstone with good reservoir quality in the Tarbert formation. The gas/water contact in the Tarbert formation has been estimated at 2870 metres based on pressure data. In the Statfjord group, the well encountered a 12-metre gas column in sandstone with moderate reservoir quality. The gas/water contact was proven at 3506 metres. The secondary exploration target in the lower part of the Statfjord group is aquiferous.
The discovery will be considered for development as part of the “Oseberg Future Phase 2” project.
The well was drilled to a measured and vertical depth of 4083 and 3928 metres below the sea surface, respectively, and was terminated in the Statfjord group in the Lower Jurassic. Water depth is 99 metres. The well is now being permanently plugged and abandoned.
Well 30/9-28 S was drilled by the Songa Delta drilling facility, which will now proceed to drill a shallow gas pilot, 30/6-U-27 in production licence 053, where Statoil is the operator.
