Lundin Petroleum AB (Lundin Petroleum) through its wholly owned subsidiary Lundin Norway AS (Lundin Norway) is pleased to announce that the Johan Sverdrup appraisal well 16/3-5 located in PL501 has encountered a 30 meter gross oil column in Upper Jurassic sandstone and Permian Zechstein Group carbonate reservoir.
The well is located 3 km south of appraisal well 16/3-4 and 3 km east of appraisal well 16/2-7, both in PL501. A comprehensive logging and coring program has been successfully completed as well as two production tests (DST).
Well 16/3-5 found a 30 metre gross oil column, shallow to depth prognosis, consisting of a 14 metre Upper Jurassic sandstone of excellent quality above a 16 metre oil column in a Zechstein Group carbonate of varying reservoir quality.
Two production test (DST) were conducted investigating flow properties of the Zechstein carbonate as well as the Upper Jurassic sandstone. The first DST test in the Zechstein carbonate resulted in low flow rates. Logs, core and losses while drilling are indicating upside potential for better flow properties within the Zechstein sequence. The second DST test in the Upper Jurrassic sandstone sequence tested through a restricted "48/64" choke resulting in a flow rate in excess of 4,700 barrels of oil per day (bopd). The DST showed exceptional flow properties, better than estimated from log evaluations. DST analysis indicates a laterally continuous reservoir without any flow barriers.
The well will now be plugged and abandoned. The total depth of the well is 2,025 metres below mean sea level.
The well was drilled using the semi-submersible drilling rig Bredford Dolphin. The rig will now move to PL359 to drill the Luno II exploration prospect operated by Lundin Petroleum.
Ashley Heppenstall, President and CEO Lundin Petroleum commented:"We are extremely pleased with the test results from this latest appraisal well which in terms of reservoir quality of the Volgian reservoir represents one of the best tests ever seen in the North Sea. The Zechstein carbonate test indicates upside potential which will require further evalution".
Lundin Norway is the operator in PL501 with 40 percent interest. Partners are Statoil Petroleum AS with 40 percent interest and Maersk Oil Norway AS with 20 percent interest.
