The 13/25-1 well was drilled on the Halibut Horst in the Outer Moray Firth, reaching a TD of 1,532 ft (467 m) in granite basement.
It intersected 41 ft (12.5 m) of hydrocarbon-bearing sands within a 68-ft (20.7-m) hydrocarbon column. The sands have porosity in the range of 25-33%, and indications are that the oil is heavy.
P&A operations have started.
Robin Allan, Premier’s director of exploration and North Sea, said: “The Bagpuss well has proven a significant volume of oil in place.
“We will now work with our partners to carry out a full analysis of the hydrocarbons and reservoir encountered to ascertain whether commerciality can be established.”
