ConocoPhillips has completed drilling on wildcat well 1/9-7 – the Tommeliten Alpha structure in production license 044 in Sentralgraben in the North Sea. The primary purpose of the drilling activity was to test the potential for hydrocarbons in sandstone from the Upper Jurassic Age, and to delimit the Tommeliten Alpha discovery made in 1976 in cretaceous rocks.
ConocoPhillips carried out the drilling activity using the jackup Mærsk Giant. The company drilled the well to 75 m of water, and completed it at a measured depth of 4,947 m under the sea surface. ConocoPhillips has plugged and abandoned the 1/9-7 well and will move the rig to production license 018 for production drilling.
The company found hydrocarbons in the cretaceous section, but not in strata of the Upper Jurassic Age. The well provided important information for any future commercialization of the Tommeliten Alpha discovery.
The drilling activity was conducted in rocks with high temperature and pressure, and provided positive experiences with the use of new technology, which may be significant for similar drilling activities in the area.
Production license 044 was awarded in the 3rd licensing round in 1974.
