Galp Energia SGPS SA’s (LS:GALP) shares jumped after the Portuguese oil company said a well test “potentially” indicates Mopane could be an important commercial find in Namibia.
The stock climbed as much as 21% in Lisbon to €19.37, the highest since 2007.
“The flows achieved during the well test have reached the maximum allowed limits of 14,000 barrels of oil equivalent per day, potentially positioning Mopane as an important commercial discovery,” Galp said in a regulatory filing on Sunday.
“In the Mopane complex alone, and before drilling additional exploration and appraisal wells, hydrocarbon in-place estimates are 10 billion barrels of oil equivalent, or higher.”
Galp said on Sunday that it “successfully” completed the first phase of the Mopane exploration campaign with the conclusion of the Mopane-1X well testing operations. Galp said it plans to further explore, appraise and develop the wider Mopane complex.
