OSLO, Norway -- Statoil Petroleum has proven further oil near to its Sleipner complex in the Norwegian North Sea.
The Transocean Leader drilled well 15/6-12 in 115 m (377 ft) of water, 12 km (7.4 mi) north of Sleipner Vest.
According to the Norwegian Petroleum Directorate (NPD), the aim was to prove petroleum in Middle Jurassic reservoir rocks (the Hugin formation), and in a secondary target Lower Jurassic and Triassic rocks (the Sleipner and Skagerrak formations).
The well encountered oil in a 4-m (13-ft) column in the Hugin formation in poorer quality reservoir rocks than had been anticipated. NPD estimates the discovery at 0.2-1 MMcm (7-35 MMcf) recoverable.
This was the fifth exploratory well in license PL 303, awarded in December 2003. The rig now heads north to drill wildcat well 6407/4-2 for Statoil in the Norwegian Sea.
