OMV (Norge) AS, operator of production license 817, has completed the drilling of wildcat well 15/2-2 S.
The well was drilled about 5 kilometers west of the Gudrun field in the North Sea, and about 230 kilometers west of Stavanger.
The objective of the well was to prove petroleum in reservoir rocks in the intra-Draupne Formation from the Upper Jurassic.
Well 15/2-2 S encountered the 500-metre-thick intra-Draupne Formation, consisting of multiple thin sandstone layers totaling 23 meters with poor reservoir properties.
Oil samples were taken from two different sand layers with different pressure regimes. Oil shows were also registered throughout the entire interval in the Upper Jurassic.
Due to the limited thickness of the sandstone layers and uncertainty in their dispersion, the preliminary estimate of the size of the discovery is between 0.95 - 5.55 million standard cubic meters (Sm3) of recoverable oil equivalent. The licensees will evaluate the well result to define the volume potential in different reservoir zones and will assess the discovery alongside other prospects in the production license.
The well was not formation-tested, but data acquisition and sampling were undertaken. This is the first exploration well in production licence 817. The license was awarded in APA 2015.
Well 15/2-2 S was drilled to a vertical depth of 4723 meters below sea level and was terminated in the Draupne Formation in the Upper Jurassic.
The water depth is 111 meters. The well will now be permanently plugged and abandoned.
Well 15/2-2 S was drilled by the Deepsea Yantai drilling facility, which is now moving on to production license 1148 in the North Sea, where Wellesley Petroleum AS is the operator.
