11 July 2007 Northern Petroleum Plc ("Northern" or "the Company") Oil Flow Testing - Ottoland-1 (sidetrack) Progress Report

Northern announces that it has been undertaking a series of oil flow rate tests since July 6th. The tests have yielded oil at unstabilised flow rates measured in excess of 1000 bopd.

The oil at present has been analysed as flowing from only a limited portion of the reservoir intersection and operations have been re-started to "clean up" drilling material from the further extent of the horizontal intersection.

Encouragingly the gas oil ratio (GOR) encountered to date appears to be low. The crude has been provisionally analysed as 33‚° API.

Derek Musgrove, Managing Director of Northern, stated: "No conclusion should be drawn at this stage except that the well is flowing oil at encouraging rates and we are undertaking clean up operations to improve it. Testing is ongoing".

In accordance with the AIM Rules - Guidance for Mining and Oil & Gas Companies, the information contained in this announcement has been reviewed and signed off by the Exploration and Technical Director of Northern, Mr Graham Heard CGeol FGS, who has over 30 years experience as a petroleum geologist.
