Doriemus Plc (AIM: DOR) announces that the operator of the Lidsey-1 well, AngusEnergy Weald Basin No.3 Limited ("Angus Energy"), yesterday logged a total of28 feet of virgin unperforated Greater Oolite reservoir from 3,320 feet downhole MD (measured depth) down to 3,348 feet MD. The top 15 feet of the Greater Oolite formation was perforated yesterday from3,320 feet MD down to 3,335 feet MD. In order to maximise the potential flow rates from the Lidsey-1 well, a moredetailed logging programme will be undertaken to determine the exact locationof the current producing interval, the oil water contact point and potentiallyto isolate this water.
