Lundin Petroleum appraisal well tests Viodo discovery, offshore Congo

Lundin Petroleum AB (Lundin Petroleum) is pleased to announce that the Viodo Marine-4 vertical appraisal well (VIM-4) located in Block Marine XI, offshore Congo Brazzaville, has tested hydrocarbons at a combined maximum flow rate of approximately 2,600 barrels of oil per day (bopd) and 7.0 million cubik feet gas per day (MMscfg/day) following two drill stem tests.

The well, the fifth on and around the Viodo accumulation, adds to the understanding of reservoir quality and fluid distribution within the structure and will now be used in conjunction with other well data and specially processed seismic data to determine the distribution of reservoir quality within the field. The results of this work will form the basis for future conceptual development studies and assessments of commerciality. The well has been plugged and abandoned.

Lundin Petroleum has an 18.75 percent working interest in Block Marine XI where SOCO International is the operator.

The Company is listed at the Nordic Exchange, Sweden (ticker "LUPE"). Lundin Petroleum has proven and probable reserves of 265 million barrels of oil equivalent (MMboe).
