BP's (BP) new GBP4B investment in the giant Clair field is something of a turnaround in terms of commitment to the North Sea, notes Evolution Securities. Says that in recent years the majors have tended to talk more about redeploying capital to less mature regions with greater prospectivity.
 Thursday's announcement highlights the fact there are still substantial fields to be developed in the North Sea , the brokerage adds. Has BP at buy, with a 510p target price. Shares trade 2.1% lower at 403p, in a negative general market and with the November Brent contract down 1.3% at $109.92.
