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%.
