Geesbrug - Another Fracturing Exceeding Expectations

                                                                                          28 September 2009


                                          Northern Petroleum Plc
                                  ("Northern" or "The Company" or "NOP")
                                                     
                           GEESBRUG - ANOTHER FRACTURING EXCEEDING EXPECTATIONS


Hydraulic  fracturing  in  the  Geesbrug-1  well of the Carboniferous  Hardenberg  and  Permian  Rotliegend
formations in the Dutch Drenthe III licence area has been successfully completed.

Post  fracturing the well has flowed on test beyond the upper range of Northern's expectations with  stable
gas  flow  rates of 450,000 m3/d (16.7 MMscf/d) and flowing wellhead absolute pressures of  170  bar  (2465
psia)  on  a  36/64"  choke. Measurements made during tests combining flow from  both  the  Rotliegend  and
Hardenberg formations, indicated that the Rotliegend formation alone is capable of flowing at over  260,000
m³/d (9.6 mmscf/d).

This  highly  successful five well programme of hydraulic fracturing of reservoirs carried out  at  Brakel,
Wijk  en  Aalburg, Ottoland, Grolloo and Geesbrug over the last ten months is now concluded.   Construction
activities  for  short pipelines have commenced for the tie in for production of the Geesbrug  and  Grolloo
fields.

These  results also have much relevance to the Tiendeveen prospect currently drilling 3.8 kms northwest  of
Geesbrug targeting the same formation.

"The  results  of hydraulic fracturing have already exceeded even our upside expectations.  Even  with  the
upcoming tests results of Rotliegend still to be analysed, shareholders and the Northern team should relish
bringing  the  Grolloo  and Geesbrug fields on production providing a strong revenue  stream."  said  Derek
Musgrove, Managing Director of Northern.

NPN maintains a 45% licence and working interest, with EBN and Dyas respectively holding  40% and 15%.
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
Petroleum Plc, Mr Graham Heard CGeol FGS, who has over 35 years experience as a petroleum geologist.

Notes to Editors:

Northern  is  an  AIM  quoted oil and gas production, development, exploration and  asset  trading  company
focused  on  petroleum producing areas of low political risk in Europe. The Company strategy is  to  obtain
significant  and  concentrated  licence positions then add value at reasonable  risk  utilising  new  ideas
together  with new drilling, seismic, completion, field development and computer technologies to  establish
economic oil and gas production.

The Company's activities are concentrated in three countries (Netherlands, Italy and England) with the risk
spread  over more than 50 projects in 12 petroleum systems.  Following the recent acquisition  of  ATI  Oil
Plc, Northern holds over 103 million barrels of reported Proven & Probable Reserves. It has interests in  4
producing fields, both onshore and offshore, one of which it manages.

The  development  of six onshore oil and gas fields is being progressed in The Netherlands  under  Northern
management (Northern Petroleum Nederland B.V.) with Dyas B.V., EBN, the Netherlands' state oil company, and
NAM.

Northern  currently  manages the largest licensed exploration area in Italy, over 15,000km²,  predominantly
offshore,  but  includes six onshore permits in the Po Valley gas and oil province  in  the  north  of  the
country.

UK  production  comes from a 10% interest in the Horndean oil field and a 5% interest in the  Avington  oil
field,  both in West Sussex and Hampshire respectively. It also has planning consents to drill in the  near
future  an eastward extension of the Horndean oil field and an exploration well at Havant. Northern  has  a
50% interest in these ventures.
