Thanks to local geological conditions and acquired drilling knowledge the risk of an oil blow-out is very low.
Although the Barents Sea is far north, experience and knowledge of the geology in the area show that drilling there is not more complicated than drilling elsewhere on the Norwegian continental shelf. In the Barents Sea, the reservoirs are not under high pressure, in contrast to certain places in the North Sea and the Norwegian Sea.
Based on relevant historical statistics there is a probability of one blow-out for every 7100 exploration wells. This means that the risk of a blow-out during an exploration drilling operation is 0.014 percent. Since 1969 some 1500 exploration wells have been drilled on the Norwegian continental shelf, with 130 wells in the Barents Sea, and no blow-outs have occurred.
