Lundin assesses Edward Grieg upside

May 12, 2014

Lundin Petroleum (Lundin Petroleum), through its wholly-owned subsidiary Lundin Norway (Lundin Norway), is pleased to announce that the appraisal drilling and testing of the well 16/1-18 on the Edvard Grieg field in the North Sea sector of the Norwegian Continental shelf has been successfully completed.

The Edvard Grieg field was discovered by well 16/1-8 drilled in 2007. The appraisal well 16/1-18 was drilled 2.4km east of the Edvard Grieg production platform.

The objective of the well was to appraise the reservoir properties in the south eastern part of the Edvard Grieg field in order to optimize the drainage strategy and drilling of production wells in this part of the field.

The well encountered approximately 62m of oil bearing conglomeratic sandstone sequence dated late Upper Jurassic. The reservoir sequence was cored and an extensive logging program was acquired. Good reservoir quality was established in the upper 43m and moderate reservoir quality in the lower 19m of the oil-bearing zone. An oil down-to situation was established.

A production test (DST) was carried out in a 13m perforation interval in the lowest part of the oil-bearing zone. The test yielded over 800 bbl/d through a 28/64in. choke, demonstrating good permeability and good vertical communication across the entire 62m oil zone.

The upper part of the reservoir with the best reservoir quality was planned to be perforated and tested in a comingled test with the lower zone, but this was cancelled due to operational issues. Nevertheless, a mini-DST in the upper oil bearing zone confirmed good quality reservoir properties.

Ashley Heppenstall, President and CEO of Lundin Petroleum, said: "The results of the Edvard Grieg appraisal well provided encouraging results in respect of the quality of the conglomeratic reservoir, which is much better than seen in other wells. This provides upside in relation to the resource contribution from this reservoir, where we previously assumed low recovery factors. The lack of sandstone reservoir at this location is however disappointing. At this stage I expect the impact on Edvard Grieg resources to be neutral with upside remaining from the conglomeratic reservoir."

Appraisal well 16/1-18 was drilled to a vertical depth of 2361m below mean sea level (MSL) and was terminated in the Granitic basement. The well will be permanently plugged and abandoned. The water depth is 109m.

The well was drilled by the Island Innovator drilling facility, which will now proceed to production licence 492 in the Barents Sea to drill appraisal well 7120/1-4 S on the 7120/1-3 (Gotha) oil discovery, where Lundin is the operator.

Lundin Norway is the operator of PL338 with a 50% interest. The partners are OMV Norge with 20%, Statoil Petroleum with 15% interest and Wintershall Norge with 15% interest.
