Calling the find commercial, Equinor estimated the 16/1-29 S “Lille Prinsen” well found 15-35 million boe of recoverable oil in its main target.
It also found oil in a shallower layer “with very good reservoir quality” but did not evaluate quantity.
The Odfjell Drilling Deepsea Bergen semisubmersible rig drilled the 16/1-29 S well to 1,987 m vertical depth, 2,001 m measured depth below sea surface, terminating in basement rock, according to the Norwegian Petroleum Directorate. Water depth is 114 m.
The well is northeast of Ivar Aasen oil field, about 2 km south of the Verdandi discovery well.
It encountered an oil column of about 95 m total, with 17 m of efficient reservoir in clastic rocks with moderate to good reservoir quality. The oil-water contact is at 1,947 m below sea surface.
The shallower, unevaluated discovery, according to NPD, is in thin Eocene Grid sandstone layers totaling 10 m in an interval of about 30 m. About 5 m of pay was gas and 5 m oil.
Pressure data indicated depths below sea surface of 1,436 m for the gas-oil contact and 1,472 m for the oil-water contact, NPD said.
The well cut 15 m of gas pay in Paleocene Heimdal and did not encounter the gas-water contact.
Equinor operates PL 167 with a 60% interest. Lundin Norway AS and Spirit Energy Norge AS hold 20% interests each.
