Statoil Petroleum has made a small gas discovery on the 7325/1-1 well on production license (PL) 615 in the Barents Sea.
The well was drilled about 56km northeast of the Wisting Central oil discovery 7324/8-1, operated by OMV, in the Barents Sea, 360 km north of Hammerfest.
The primary exploration target for the 7325/1-1 well was to prove petroleum in reservoir rocks of Middle Triassic (Kobbe formation). The secondary exploration target was to prove petroleum in reservoir rocks of Middle and Early Triassic (Snadd and hooded seal formations).
Well 7325/1-1 encountered about 10m of sandstone with traces of hydrocarbons in the Kobbe formation. Reservoir properties were poor. There were also encountered about 55m of net reservoir rock in Snadd formation, of which 10m was filled with gas.
Poor reservoir properties in the Kobbe and Snadd formation prevented the creation of pressure gradients. There was no evidence of sandstone in Klappmyss Formation, however, it was discovered about 10m gross sandstone of poor quality in the Lower Triassic reservoir rocks (gray seal formation). Preliminary analysis indicates that the discovery is commercial. It is performed data collection and sampling.
The well has been plugged and abandoned.
This is the second exploration well in PL615. The license was awarded in the 21th licensing round in 2011.
Well 7325/1-1 was drilled by the Transocean Spitsbergen. The drilling rig will now proceed to PL614 to drill wildcat well 7324/9-1.
