Northern Sun Exploration Co. Inc. announced that it has completed the initial testing of the eight exploration wells from its December 2007 drilling program. After a comprehensive testing period, the company reported that six of the eight exploration test wells look to be economic, and once the wells have been tied in, the exploration program will have added 102 bbls of oil equivalent per day. The company's 50% working interest 1-23-87-6-W6M, 2 250 metre multi-zone test well is producing oil and liquids from the Gething zone, as the deeper zones proved to be uneconomic. The well is being carefully managed to optimize a gas and oil/liquids production rate and minimize the water cut. The well is currently producing 10 BOE per day and has been equipped to inject water for disposal in the deeper zones. The water disposal into the deeper zones will commence when the operator has received regulatory approval which should be granted before the end of June 2008. The oil well is currently producing 19 degree API oil at a rate of 6-10 BOE per day.
