20/12/2013 Lundin Norway AS, operator of production licence 410, has completed drilling of wildcat well 16/5-5. The well was dry.
The well was drilled about 20 kilometres south of the Edvard Grieg field in the central part of the North Sea.
The purpose of the well was to prove petroleum in Jurassic/Triassic reservoir rocks in a southern segment of the 16/4-6 S oil discovery. The well encountered 150 metres of fine-grained sandstone in Triassic, with poorer reservoir quality than expected.
Small oil volumes were sampled from this sandstone without successful establishment of an oil gradient. The reason for this is that the reservoir zone is dense. Sandstone with better reservoir quality was proven underneath this zone. Pressure data shows that there is a pressure barrier between the 16/4-6 S discovery well to the west and well 16/5-5. The well is classified as dry.
Extensive data acquisition and sampling have been carried out in the well.
This is the first exploration well in production licence 410. The licence was awarded in APA 2006.
The well was drilled to a vertical depth of 2060 metres below the sea surface and was terminated in Triassic rocks. The water depth is 100 metres. The well will be permanently plugged and abandoned.
Well 16/5-5 was drilled by the Bredford Dolphin drilling facility, which will now proceed to drill appraisal well 16/3-8 on the 16/2-6 Johan Sverdrup discovery in production licence 501, where Lundin Norway AS is the operator.
