Press Release

Stockholm 6 August 2014

Lundin Petroleum completes Tembakau appraisal well in Malaysia Lundin Petroleum AB (Lundin Petroleum) is pleased to announce that it has completed the first well in its 2014 Malaysian drilling campaign with the successful drilling and testing of Tembakau-2 appraisal well in Block PM307, offshore Malaysia.

Tembakau-2 was drilled by the jackup rig West Prospero to a depth of 1,450 metres in 68 metres water depth. The well targeted stacked gas reservoirs in Miocene aged sands in a large, low-relief, structure discovered by Lundin Petroleum's Tembakau-1 well in late 2012.

Tembakau-2 is 3.7 kilometres to the south of the discovery well and penetrated 22 metres of gross gas sands in four sand intervals between 900 metres and 1300 metres subsea. The main two reservoirs penetrated were fully cored and the well was comprehensively logged.

The reservoir deliverability was measured through production testing. The "I20" sand produced at stabilised flow rate of 15.8 million standard cubic feet per day of gas over a 8 hour period on 64/64" choke and the "I10" sand produced at stabilised flow rate of 15.9 million standard cubic feet per day of gas over a 8 hour period on

72/64" choke.

Each perforated interval was 3 metres. The gas produced is dry with approximately 0.5% CO2. Multiple samples were obtained for further laboratory analysis. The data gathered will be analysed and integrated with 3D

seismic information to update the current gross contingent resource estimate of gas and to provide reservoir information for conceptual development studies.

Ashley Heppenstall, President and CEO, commented; "The appraisal drilling results from Tembakau are positive. We are incorporating the results of the well into an updated resource estimate. We will now move forward in reviewing conceptual development options and I am hopeful that this will lead to another commercial development project in Malaysia."

The well has been plugged and abandoned and the West Prospero rig has moved to the Bertam oil field well head platform location, also in PM307, to commence development drilling.

Lundin Petroleum holds a 75 percent interest in PM307 through its subsidiary Lundin Malaysia BV. Lundin Malaysia BV's partner is PETRONAS Carigali Sdn. Bhd. with 25 percent interest. Lundin Malaysia BV operates seven blocks in Malaysia, namely PM307, PM308A, PM308B, PM319, SB303and SB307/308.

Such statements and information (together, "forward-looking statements") relate to future events, including the Company's future performance, business prospects or opportunities. Forward-looking statements include, but are not limited to, statements with respect to estimates of reserves and/or resources, future production levels, future capital expenditures and their allocation to exploration and development activities, future drilling and other exploration and development activities. 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.

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. . Unless otherwise stated, all contingent resource estimates contained herein are the best estimate ("2C") 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. Unless otherwise stated, all Prospective Resource estimates contained herein are reflecting a P50 Prospective Resource estimate. Risked Prospective Resources reported herein are partially risked. They have been risked for chance of discovery, but have not been risked for chance of development.

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.
