New Application and Drilling Update New Application to Drill in HampshireNorthern has today submitted an Application for Planning Consent for thedrilling of the Hedge End-2 well from a site towards Botley owned by theHampshire District Council. The well will test an oil discovery made in 1988which was cored and logged but not tested, a decision believed to have beentaken due to poor core recovery and the oil market conditions at the time. Morerecently Northern has materially revised the methods for interpretation of logsin the Great Oolite formations in the Weald Basin and as a result believes thatHedge End-1 was an oil discovery of 50 to 125 million barrels of oil in place.The substantial range of the estimates is due to the Hedge End-1 well beingdrilled entirely above the oil water contact. Northern is the licence Operatorholding a 50% interest.Isle of Wight - UpdateNorthern also announces that final agreement has been reached with TheSecretary of State for Environment, Food and Rural Affairs regarding the sitefrom which the Bouldnor Copse-1 well will be drilled.
