Norwegian oil and gas major Statoil, operator of production licence 169, has concluded the drilling of wildcat well 25/11-28, offshore Norway. The well is dry.
The company received a drilling permit from the Norwegian Petroleum Directorate (NPD) to drill the well in August 2015. The well was drilled 13 kilometres south of the Grane field in the North Sea. This is the 15th exploration well in production licence 169.
According to the NPD, the objective of the well was to prove petroleum in Upper Jurassic reservoir rocks (the Draupne formation) and in the Permian (the Rotliegend group). The well encountered 22 metres of sandstone in the Upper Jurassic, 7.5 metres of which with good reservoir quality. No reservoir rocks were proven in the Permian.
Extensive data acquisition and sampling have been carried out.
The well was drilled to a vertical depth of 2563 metres below the sea surface, and was terminated in basement rock.
Water depth at the site is 118 metres. The well will now be permanently plugged and abandoned, the directorate said.
The well was drilled by the Songa Trym drilling rig, which will now drill wildcat well 34/8-16 S in production licence 120 in the northern North Sea, where Statoil Petroleum AS is the operator.
