Resource Estimates 
STOCKHOLM, SWEDEN -- (Marketwire) -- 10/21/11 -- Lundin Petroleum AB
(Lundin Petroleum) (TSX:LUP)(OMX:LUPE) is pleased to announce that
following the drilling of appraisal well 16/2-10 located in the
Norwegian North Sea the operator of PL265, Statoil ASA, has announced
a material increase to the resource estimates for the Aldous Major
South discovery. The Aldous Major South and Avaldsnes discoveries
located in PL501 are one large connected discovery. 
The gross contingent recoverable resources of the Aldous Major South
discovery located in PL265 have following analysis of the data from
the appraisal well increased from a range of 400 to 800 million
barrels of oil to 900 million to 1.5 billion barrels of oil. The
gross oil column in the appraisal well is approximately 60 metres
with high net to gross and excellent reservoir characteristics. 
Lundin Petroleum has previously announced a range of gross
recoverable contingent resources for the Avladsnes discovery located
in PL501 of between 800 and 1800 million barrels of oil. The
Avaldsnes/Aldous Major South discovery is therefore now estimated to
contain gross recoverable contingent resources of 1.7 to 3.3 billion
barrels which is one of the largest discoveries on the Norwegian
Continental Shelf.

commercially recoverable due to one or more contingencies. 
The contingent resource range has been estimated including
uncertainties in reservoir extent, reservoir properties and recovery
factors. The main contingency preventing the classification of the
