Lundin Petroleum has started drilling appraisal well 7220/11-4 (Alta-4) on the Alta discovery in PL609, on the Loppa High in the southern Barents Sea.
The Alta-4 well is about 2km south of the original discovery well 7220/11-1 and is the fourth well to be drilled on the Alta discovery. The main objective of the Alta-4 well is to further appraise the Alta discovery and to provide a calibration point for the drilling of a horizontal well for a possible extended well test that is being planned for 2018.
The Alta discovery is estimated to contain gross contingent resources of between 125-400 MMboe.
The Alta-4 well will be drilled by the semisubmersible drilling rig Leiv Eiriksson and is expected to take about 65 days.
Lundin Norway is the operator of PL609 with a 40% working interest.
