1112 GMT [Dow Jones] Tullow Oil's (TLW.LN) update shows the company has had a very successful 1H, with 73% drilling success, says Charles Stanley. Also notes some exciting prospects for 2H, in particular Owo-1 in Ghana. Says '10 will be a landmark year for the group as its Jubilee field comes on stream at the end of the year. For investors who want long-term exposure to a group with an excellent exploration record and an exciting drilling program, Tullow's underperformance could provide a good entry point, Charles Stanley says. However, reckons the share price is up with events at the moment. Reiterates hold. Shares +3.5% at 1077p.
