Well confirms Grevling discovery

Norwegian Petroleum Directorate has today announced that Talisman has
completed drilling of the appraisal well on the Grevling prospect in
production license 038D in the North Sea. Det norske has a 30 percent
interest in the license. In the appraisal well the oil-water contact was
identified 83 m deeper than in the discovery well. The operator,
Talisman Energy Norge, will now work with different development
solutions.
Oil production on the Norwegian continental shelf is dramatically
decreasing because few new fields are discovered and put into
production. The results of the appraisal well on Grevling is encouraging
with regard to a speedy development of the field. Det norske who owns 30
percent of the discovery, will support and assist the operator Talisman
so a speedy economic development of Grevling can be realized. It is too
early to conclude, but a development of Grevling may also lead to a
possible recovery of the resources found in Storskrymten, 5 km west of
Grevling.
"Grevling, will together with other commercial discoveries in which Det
norske has interests, Frøy, Draupne, Storklakken and Jetta, help to
reduce the fall in oil production on the NCS from 2013 and onwards,"
says CEO. Erik Haugane.
