Lundin Petroleum AB: Oil Discovery in Luno II Exploration Well Offshore Norway

STOCKHOLM, SWEDEN--(Marketwired - Apr 8, 2013) - Lundin Petroleum AB (Lundin Petroleum) (LUP.TO)(LUPE.ST) through its wholly owned subsidiary Lundin Norway AS (Lundin Norway) is pleased to announce that the drilling of exploration well 16/4-6S on the Luno II prospect has resulted in a potentially significant oil discovery. The well is located in PL359 in the central North Sea sector of the Norwegian Continental Shelf (NCS). The well will now be tested.

The well was drilled in water depths of 101 metres and is located on the south western flank of the Utsira High approximately 15 km south of the Lundin Petroleum operated Edvard Grieg field.

The well has drilled through a section of close to 200 metres of sand with a high net-to-gross content. A gross oil column in excess of 40 metres has been proven. The oil water contact was encountered at approximately 1,950 metres below mean sea level. It is a light oil of good quality. The pressure data indicates that the petroleum system in Luno II is different to that seen in the Edvard Grieg and Johan Sverdrup fields. A comprehensive coring, logging and fluid sampling program has been performed. The discovery will now be production tested.

Ashley Heppenstall, President and CEO of Lundin Petroleum AB, commented: "We are very pleased that Luno II appears to be another significant discovery on the Utsira High. The existence of a thick reservoir section at this location is excellent news. The reservoir quality, whilst not the same as Johan Sverdrup, appears good and will now be tested. We expect to provide a range of recoverable resources from the discovery after testing is completed in 2-3 weeks time".

The well was drilled using the semi-submersible drilling rig Bredford Dolphin. Following the completion of the testing programme the rig will be moved to the Lundin Norway operated PL501 to continue the appraisal drilling on the Johan Sverdrup discovery.

Lundin Norway AS is the operator of the PL359 with a 40 percent interest. The partners are Statoil Petroleum ASA with 30 percent and Premier Oil plc with 30 percent interest.

Ultimate recovery of reserves or resources are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management.

All statements other than statements of historical fact may be forward-looking statements. Statements concerning proven and probable reserves and resource estimates may also be deemed to constitute forward-looking statements and reflect conclusions that are based on certain assumptions that the reserves and resources can be economically exploited. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as "seek", "anticipate", "plan", "continue", "estimate", "expect", "may", "will", "project", "predict", "potential", "targeting", "intend", "could", "might", "should", "believe" and similar expressions) are not statements of historical fact and may be "forward-looking statements". Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements.

These statements speak only as on the date of the information and the Company does not intend, and does not assume any obligation, to update these forward-looking statements, except as required by applicable laws. These forward-looking statements involve risks and uncertainties relating to, among other things, operational risks (including exploration and development risks), productions costs, availability of drilling equipment, reliance on key personnel, reserve estimates, health, safety and environmental issues, legal risks and regulatory changes, competition, geopolitical risk, and financial risks. These risks and uncertainties are described in more detail under the heading "Risks and Risk Management" and elsewhere in the Company's annual report.

Reserves and Resources

Unless otherwise stated, Lundin Petroleum's reserve and resource estimates are as at 31 December 2011, and have been prepared and audited in accordance with National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities ("NI 51-101") and the Canadian Oil and Gas Evaluation Handbook ("COGE Handbook")."). Unless otherwise stated, all reserves estimates contained herein are the aggregate of "Proved Reserves" and "Probable Reserves", together also known as "2P Reserves". For further information on reserve and resource classifications, see "Reserves and Resources" in the Company's annual report.

Contingent Resources

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 are not currently considered to be commercially recoverable due to one or more contingencies. Contingencies may include factors such as economic, legal, environmental, political and regulatory matters or a lack of markets. There is no certainty that it will be commercially viable for the Company to produce any portion of the Contingent Resources.

Prospective Resources

Prospective Resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both a chance of discovery and a chance of development. There is no certainty that any portion of the Prospective Resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the Prospective Resources.

BOEs

BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf : 1 Bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
