Lundin Norway AS, a wholly owned subsidiary of Lundin Petroleum AB, spudded three wells: its second Alta appraisal well in the Barents Sea, an appraisal well on Edvard Grieg field in the Norwegian North Sea, and the partner-operated Zeppelin exploration well in the southern North Sea.
Alta appraisal well7220/11-3 in PL609 is 4.3 km south of Alta discovery well 7220/11-1 (OGJ Online, Mar. 25, 2015), and 3.4 km northeast of recently completed appraisal well 7220/11-2 (OGJ Online, June 12, 2015). The first appraisal well encountered a 50-m gas column in reservoir rocks of good-to-poor quality, with a sidetrack encountering gas and oil.
The main objectives of well 7220/11-3 are to confirm the reservoir model and prove the presence of hydrocarbon columns and fluid contacts similar to those established in the Alta discovery well, and to test the reservoir properties of the Permian carbonates, Lundin says.
Drilled by Island Drilling’s Island Innovator semisubmersible rig, the well will reach a total depth of 2,070 m below mean sea level over a period of 60 days. Lundin Norway operates PL609 with 40% working interest, while DEA Norge AS and Idemitsu Petroleum Norge AS each hold 30%.
Lundin says the objectives of well 16/1-23 S are to confirm the geological model at this part of the field so the company can optimize drainage strategy and the placement of development wells, and to test for upside reserve potential in the field, which is estimated at up to 50 million boe (gross).
Drilled by the Rowan Viking jack up rig, the well will reach a total depth of 2,200 m below mean sea level over a period of 60 days. Lundin Norway operates PL338 with 50% working interest. Partners are OMV Norge AS 20%, Statoil Petroleum AS 15%, and Wintershall Norge AS 15%.
Zeppelin exploration well 10/4-1 in PL734, operated by Wintershall, lies in the southern North Sea 35 km southeast of Yme field.
The main objectives of well 10/4-1 are to prove the presence of hydrocarbons in sandstones of the Middle to Late Jurassic Vestland Group. Lundin estimates the Zeppelin prospect to have the potential to contain unrisked, gross prospective resources of 152 million boe.
Drilled by Dolphin Drilling AS’s Borgland Dolphin semisubmersible rig, the well will reach 2,300 m below mean sea level over a period of 30 days. Wintershall operates PL734 with 40% interest, while Lundin Norway and Centrica Resources (Norge) AS each hold 30%.
