Lundin Petroleum AB: Aldous Major South Appraisal Well

Lundin Petroleum AB: Aldous Major South Appraisal Well Confirms
Extension to the North 
STOCKHOLM, SWEDEN -- (Marketwire) -- 10/18/11 -- Lundin Petroleum AB
(Lundin Petroleum)(TSX:LUP)(OMX:LUPE) is pleased to announce that the
drilling of appraisal well 16/2-10 in the Norwegian North Sea has
confirmed the northern extension of the Aldous Major South discovery
in PL265. The Aldous Major South discovery is an extension of the
Avaldsnes discovery made by Lundin Petroleum in PL501. 
The appraisal well encountered a gross oil column of 50-55 metres in
sandstone of Jurassic age. 
The well was drilled using the semi submersible rig Transocean Leader
and the acquisition of further data is ongoing. 
Prior to drilling the appraisal well Statoil had estimated the gross
recoverable contingent resource range for the Aldous Major South
discovery of 400 to 800 million barrels of oil contained in PL265.
Statoil will update the contingent resource range once the data from
this appraisal well has been analysed. 
Lundin Petroleum has recently updated its gross contingent resource
estimate for the Avaldsnes discovery within PL501 to be 800 million
to 1.8 billion barrels of recoverable oil. The Avaldsnes /Aldous
Major South discovery is therefore estimated to contain gross
contingent resources of 1.2 to 2.6 billion barrels of recoverable
oil. 
Lundin Petroleum is a partner with 10 percent interest in PL265.
Statoil ASA is the operator with 40 percent, Petoro has 30 percent
and Det Norske oljeselskap ASA has 20 percent interest. 
Lundin Petroleum is the operator in PL501 with 40 percent interest.
Partners are Statoil Petroleum AS with 40 percent interest and Maersk
Oil Norway AS with 20 percent interest.

CONTINGENT RESOURCE ESTIMATES 
Contingent Resources are those quantities of petroleum estimated, as
of a given date, to be potentially recoverable from known
accumulations using established technology or technology under
development, but which are not currently considered to be
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
resources as reserves is the definition of a conceptual development
plan. 
The recovery and production estimates of the Company's resources
provided herein are only estimates and there is no guarantee that the
estimated resources will be recovered or produced. Actual resources
may be greater than or less than the estimates provided here. There
is no certainty that it will be commercially viable for the Company
to produce any portion of these resources. 
The effective date of the resource estimate is the date of this press
release.
