Swedish independent oil and gas exploration company Lundin Petroleum has commenced drilling of exploration well 8/5-1 in PL453S to confirm the presence of hydrocarbons in the Upper to Middle Jurassic reservoirs.

Lundin said the drilling will target the Ogna prospect, which is located about 65km from the Ula Field and 50km to the east of the main Central Graben area, in the Norwegian Danish basin of the North Sea.

The company will deploy jack-up rig Mærsk Guardian to drill the well to a total depth of 2,444 metres below mean sea level, which is expected to take about 50 days.

The Ogna prospect is estimated to contain unrisked, gross, prospective resources of 156 million barrels of oil equivalent (MMboe).

Lundin said the prospect can be a stand-alone development since it is a faulted anticline developed above a salt controlled high and placed in moderately shallow-water (60-70m).

The prospect’s most important target interval is the Upper and Middle Jurassic sand prone sequence, while the secondary targets are the underlying Triassic and the overlying Cretaceous and Palaeocene.

The presence and maturity of a suitable source rock and the reservoir quality of the target horizons are the main concern areas associated with the prospect, said the company.

Holding 35% of the working interest through its wholly-owned subsidiary Lundin Norway, Lundin Petroleum is the operator of PL453.

Other participating companies in the field are Det norske oljeselskap and Noreco, each with 25% interest, and VNG Norge with the remaining 15% interest.
