The company discovered oil at two appraisal wells at the Alta discovery, which is located 10km to 20km northeast of the company’s Gohta discovery in the Barents Sea South.
Completed in October 2014, the Alta discovery well 7220/11-1 was estimated to hold 125 to 400 million barrels of oil equivalents (MMboe).
The appraisal well 7220/11-3 is located approximately 4km south of the original Alta discovery well 7220/11-1 and approximately 3km northeast of the previous appraisal well 7220/11-2.
The 7220/11-3 well was drilled to determine the reservoir model and the presence of hydrocarbon columns and fluid contacts.
During drilling program, the company identified 120m thick hydrocarbon bearing interval at the well 7220/11-3. The well, however, was plugged due to technical problems.
Later, Lundin drilled a geological sidetrack, 7220/11-3 A, approximately 400m southeast of 7220/11-3.
The well, which encountered a gross hydrocarbon column of 74m, is planned to be temporarily plugged and abandoned. The well will be drilled deeper and eventually undergo production test later.
Lundin said that the pressure data from wells 7220/11-3 and 7220/11-3 A show communication with the discovery well 7220/11-1.
The drilling rig Island Innovator was used to drill the wells to total vertical depths of 1,925 and 1,962m below mean sea level.
Lundin Petroleum COO Alex Schneiter said: "I am very pleased that all three Alta wells and the two sidetracks have proven moveable gas and oil.
"More importantly we have established good pressure communication between all wells indicating a connected hydrocarbon accumulation over an extensive area.
"We will likely drill up to two further appraisal wells in 2016 in addition to re-entering the latest appraisal well to perform a production test. The Island Innovator rig will now move to the north of PL609 to drill the Neiden prospect."
PL609 is operated by Lundin Norway with 40% stake, while partners DEA Norge and Idemitsu Petroleum Norge each hold 30%.
