"Given that this did not exceed expectations, we believe that the P50 reserve estimate is unchanged but believe that the range between the P10 and P90 numbers will be tightened," he says. "This demonstrates Tullow has a good understanding of how the reservoir works." Gives buy rating. Shares +1.0% at 1,115p.
