BG Group AS operator of production licence 373 S, is in the process of completing the drilling of wildcat wells 34/3-4 S and 34/3-4 A.
The wells were drilled about 5 kilometres east of the Knarr field in the northern part of the North Sea.
The purpose of wildcat well 34/3-4 S was to investigate a large channel system in reservoir rocks in the Pleistocene. The well encountered a 250-metre thick channel system, about 50 metres of which was of very good reservoir quality. Traces of gas were encountered in two thin sandstone layers.
The purpose of well 34/3-4 A was to prove petroleum in lower Jurassic reservoir rocks (the Cook formation). Well 34/3-4 A encountered about 110 metres of the Cook formation, 53 metres of which was sandstone with good reservoir quality and traces of gas.
