Statoil group makes two minor discoveries at Njord North Flank

Oct. 18, 2016
Exploration well 6407/7-9 S (NF-2) at the Njord North Flank in the Norwegian Sea encountered a 102-m gross oil-bearing reservoir in Middle and Lower Jurassic sandstones of the Ile and 157-m gross gas condensate-bearing column in Lower Jurassic sandstones in the Tilje formation.

Exploration well 6407/7-9 S (NF-2) at the Njord North Flank in the Norwegian Sea encountered a 102-m gross oil-bearing reservoir in Middle and Lower Jurassic sandstones of the Ile and 157-m gross gas condensate-bearing column in Lower Jurassic sandstones in the Tilje formation.

Statoil Petroleum AS is operator of production license 107 C. Based on the results of 6407/7-9 S, the partnership drilled sidetrack well 6407/7-9A (NF-3) to test a fault-block lying to the east.

The sidetrack encountered a 195-m gross gas-bearing column in the Tilje formation and 140-m gross gas-bearing column in Lower Jurassic sandstones in the Are formation. No hydrocarbons were encountered in the Ile formation. Both wells are 6 km to the north of the Njord production facility.

Neither well was drillstem tested, but extensive data acquisition and sampling has been performed on both wells. Based on the data acquired, a preliminary estimate of the size of the NF-2 discovery is 1.3-18.9 million boe. Sidetrack NF-3 is estimated at 0.6-9.4 million boe.

Partner Faroe Petroleum PLC says the results are in line with predrill estimates. The partners will consider the discoveries along with other nearby discoveries for development with tie-in to the Njord field.

Wells 6407/7-9 S and 6407/7-9 A were drilled to measured depths of 4,114 m and 4,931 m below the sea surface, respectively, and vertical depths of 4,105 m and 4,127 m below the sea surface, respectively. Both wells were terminated in the Are formation from the Early Jurassic Age. Both wells were drilled in 323 m of water by Songa Offshore AS’sSonga Delta drilling facility.

Faroe in June was part of the group that encountered a 39-m gross gas, oil-bearing reservoir in the Brasse prospect in the Norwegian North Sea (OGJ Online, June 16, 2016). The firm now anticipates the spudding by yearend of an exploration well on the Eni SPA-operated Dazzler prospect in the Barents Sea.
