Swedish headquartered oil firm Lundin says its Barents Sea Alta discovery contains up to 125-400 MMboe gross contingent resources after completing its latest appraisal well.
The estimate, inline with pre-drilling estimates, comes after the re-entry of appraisal well 7220/11-3 A (Alta-3) on the eastern flank of the Alta discovery in PL609 in 400m water depth using the Leiv Eiriksson semisubmersible drilling rig (pictured).
The well is the first of a three-well drilling campaign in the Loppa High, with a re-entry on the Neiden prospect coming next, followed by an exploration well on the Filicudi prospect. Lundin hopes to prove up enough resources in the Alta/Gohta (a 2013 discovery) area to make a commercial development.
The original Alta-3 well, drilled in 2015, encountered a ca.120m gross hydrocarbon column. A production test in the gas zone in the Lower Triassic reservoir section produced a maximum of 21 MMcf/d through a 64/64in choke. There was no test planned in the oil zone.
Pressure data from wells 7220/11-3, -3A and -3 AR indicate good communication with the two previously drilled wells on the Alta discovery.
Lundin CEO Alex Schneiter said further appraisal over the Alta discovery will be required during 2017 to fully delineate this large structure.
Alta-3 was the fifth well in PL609, and was the first of three wells in a 2016 drilling campaign on the Loppa High. The next well is 60km to the north on PL609 and will see Lundin re-enter suspended well 7220/6-2 to complete the drilling on the Neiden prospect, which is estimated to contain 204 MMboe gross unrisked prospective resources.
Lundin Norway is the operator of PL609, which was awarded in 2011, with 40% interest. Partners are Idemitsu Petroleum Norge and RWE Dea Norge with 30% each.
