Lundin reports Alta appraisal results in Barents Sea

Lundin Norway AS and the Norwegian Petroleum Directorate reported results from two appraisal wells of the Alta oil and gas discovery in PL609 in the southern Barents Sea (OGJ Online, Oct. 14, 2014).

The 7220/11-2 appraisal well was drilled to a vertical depth of 2,020 m subsea in 379 m of water, some 6.5 km southwest of the 7220/11-1 discovery (OGJ Online, Mar. 25, 2015). It encountered a 50-m gas column in reservoir rocks of good to poor quality.

NPD said the oil zone is in tight rocks and a decision was made to drill a sidetrack.

Sidetrack 7220/11-2A was drilled 330 m west to a vertical depth of 2,041 m and encountered gas and oil. NPD said a formation test through a 24/64-in. choke resulted in production of 136 cu m/day of oil and 18,500 cu m/day of gas. Lundin reported rates of 860 b/d of oil and 650 Mcfd of gas.

The wells were drilled by Island Drilling’s Island Innovator semisubmersible rig, which will now drill appraisal well 7220/11-3.

Lundin holds 40% in PL609. DEA Norge AS and Idemitsu Petroleum Norge AS each have 30%.
