Results from Johan Sverdrup appraisal well

Det norske oljeselskap ASAis as partner in production licence 265, in the process of completing drilling of appraisal wells 16/2- 19 and 16/2-19Ain the Johan Sverdrup oil discovery.

The objective of the wells was to examine the extent and properties of the reservoir rocks in the northernmost part of the Johan Sverdrup discovery.

Well 16/2-19 encountered six metres gross oil-bearing sandstone of medium to good quality assumed to constitute part of the Statfjord Group. The well was drilled to a vertical depth of 2,024 metres and was terminated in basement rocks.

The license partners decided to drill a 1,000 metre sidetrack well (16/2-19A) towards the southwest in order to clarify the northern extent of the sandstones of the Draupne Formation, constituting the main reservoir on Johan Sverdrup. Here, a 12 metre gross oil-bearing sandstone/siltstone interval of medium good reservoir development was encountered in the Draupne formation. The well was drilled to a vertical depth of 1,971 metres and was terminated in basement rocks.

The well results will be incorporated into the Johan Sverdrup field development work.

The licensees in production licence 265 are Statoil (operator, 40 percent), Petoro AS (30 percent), Det norske oljeselskap ASA (20 percent), Lundin Norway AS (10 percent).
