Equinor Energy AS, operator of production licence 502, has completed the drilling of wildcat well 16/5-7. The well was drilled about 1 kilometer west of Johan Sverdrup oil field in the central part of the North Sea and 200 kilometer west of Stavanger. The objective of the well was to prove petroleum, as well as to investigate potential reservoir rocks in several levels: Upper Jurassic, Upper Triassic, Upper Permian and weathered/fractured basement rock. The well was drilled about 110 meter into basement rock, of which 77 meter of weathered and fractured basement rock with poor to moderate reservoir properties. In the upper part of the basement, the well encountered traces of oil in a zone of about 19 meter.

At this time, it is impossible to determine whether the oil is producible or simply residual. No sedimentary rocks were encountered in other levels. Pending new information and interpretation of collected data, the preliminary classification is that the well is dry. The well was not formation-tested, but extensive volumes of data have been acquired and samples have been taken.

However, the well has yielded important information about the potential for reservoir properties in the basement rock, as well as pressure communication in the area. This is the second exploration well in production licence 502. The licence was awarded in APA 2008.
