Total's Uptonia exploration well 34/6-4 on production license 554 in the Norwegian sector of the North Sea is to be plugged and abandoned as a dry well, says the Norwegian Petroleum Directorate.
The well was drilled about 6km northeast of the 34/6-2 S (Garantiana) oil discovery using the Leiv Eiriksson semisubmersible drilling rig in 390m water depth. The purpose of the well was to prove petroleum in Lower Jurassic reservoir rocks in the the Cook formation.
The well encountered about 96m of aquiferous sandstone in the Cook formation with poor to moderate reservoir quality. Data acquisition was carried out.
This is the fifth exploration well in production license 554, awarded in 2010 (APA 2009).
Well 34/6-4 was drilled to a vertical depth of 4084m below the sea surface and was terminated in the Lower Jurassic Burton Formation.
