VNG Norge has discovered oil on the Bue well, in production license (PL) 586, offshore Norway, and increased its resource estimate for the nearby Pil discovery, in the same license.
The combined resource of both finds has been estimated at 80-200MMboe by partner Faroe petroleum, which says both fields could be tie-back candidates to the nearby Njord platform.
The Bue 6406/12-3 A wildcat well encountered an 18-metre oil column in sandstones from the Rogn formation, with reservoir quality varying from good to very good. Preliminary estimates put the find at 1-4MM cu m of oil and condensate. The well was drilled close to the Pil discovery, but pressure data indicated no communication between the Pil and Bue discoveries, said Norway’s Norwegian Petroleum Directorate.
VNG also drilled appraisal well 6406/12-3 B on the 6406/12-3 S (Pil) oil and gas discovery. The Pil discovery was proven in Upper Jurassic reservoir rocks in the spring of 2014. Well 6406/12-3 B encountered an 82m oil column in sandstone in the Melke formation with good reservoir quality. The oil/water contact was encountered somewhat deeper than expected.
The resource estimate for the oil and gas discovery in 6406/12-3 S (Pil) has now been adjusted to 8.8-21.1MMcu m of recoverable oil and condensate, as well as 2.7- 6.1 billion cu m of recoverable gas. Before 6406/12-3 B was drilled, the operator’s resource figures for the discovery were 6-21MM cu m of recoverable oil and 2-6 billion cu m of recoverable gas.
Faroe Petroleum said the Pil and Bue discoveries are about 33km south east of the Njord platform, making them possible tie-back candidates to Njord.
Graham Stewart, Chief Executive of Faroe Petroleum, said: “The current resource range for the Pil and Bue discoveries together is now estimated to be between approximately 80 and 200MMboe, of which around 80% is estimated to be oil and condensate. The partners are now preparing next year’s exciting exploration and appraisal program to assess the further upside potential in the license and evaluating different development alternatives.”
The Bue and Pil appraisal wells were the second and third exploration wells in PL586. The 6406/12-3 B (Pil) appraisal well and 6406/12-3 A wildcat well (Bue) were drilled 1.7 and 2.1km, respectively, northwest of the Pil discovery well 6406/12-3 S, in 324m water depth.
Wells 6406/12-3 B and A were drilled by the Transocean Arctic (pictured) drilling facility, which will now move to PL555 in the northern part of the North Sea to drill wildcat well 33/2-1, where Lundin Norway is the operator.
