Lundin Petroleum's latest well on the Alta field in the southern Barents Sea has confirmed reservoir communication and qualities.
Lundin is now planning a sidetrack well, which will help to plan for the drilling of a horizontal well for use as in an extended well test, planned on the field next year.
Alta and the nearby Gohta field are part of a planned development, currently based on a floating production concept, with subsea wells.
The latest Alta-4 well (7220/11-4) was about 2km south of the original Alta discovery well 7220/11-1 and about 2.5km north of the previous appraisal well 7220/11-3.
The well encountered a gross hydrocarbon column of 48m, comprising 4m of gas and 44m of oil in a sequence of Permian-Triassic clastic carbonate sediments. Cores and fluid samples were also taken. Good communication was confirmed across the larger Alta structure, says Lundin.
A production test confirmed very good reservoir properties and good lateral continuity within the Permian-Triassic clastic reservoirs.
Alex Schneiter, CEO and President of Lundin Petroleum comments: “I am pleased with the good well results from Alta-4 which confirm very good reservoir properties, communication across the large Alta structure and excellent production rates. We will now proceed to plan a possible extended well test for 2018, which is the next step in moving the significant Alta discovery towards development.”
The well was drilled using the semisubmersible drilling rig Leiv Eiriksson which, following completion of the Alta-4 sidetrack well, will proceed to drill the Børselv prospect, also in PL609.
Lundin Norway is the operator of PL609 with a 40% interest. The partners are DEA Norge and Idemitsu Petroleum Norge with 30% interest each.
