The Songa Delta semisubmersible drilled the 30/11-14 and 30/11-14B wildcat wells in 107 m of water. Well 30/11-14 encountered gas columns of 23 m and 6 m in the upper section of the Tarbert formation. Well 30/11-14B encountered two gas-oil columns and an oil column of 38 m, 12 m, and 13 m, respectively, in the upper part of the Tarbert.
Both wells encountered sandstones with moderate reservoir quality in the Ness and Etive formations, which were dry.
Preliminary estimates are 1-2 million cu m of oil equivalent recoverable for 30/11-14 and 2-5 million cu m for 30/11-14B. Statoil carried out extensive data acquisition and sampling but did not conduct formation tests.
NPD said 30/11-14 was drilled to a vertical depth of 3,437 m below the sea surface and a measured depth of 3,438 m below the sea surface. Well 30/11-14B was drilled to a vertical depth of 3,343 m and a measured depth of 4,187 m. Both were terminated in the Drake formation in the Middle Jurassic.
They are the fifth and sixth exploration wells in production license 272. The wells were drilled 25 km southwest of the Oseberg South facility and 6 km southeast of the 30/11-8S Krafla discovery.
The Songa Delta will now drill wildcat 6407/7-9S in production license 107 C.
