The semisubmersible Deepsea Nordkapp drilled wildcat well 6507/5-9 S and appraisal well 6507/5-9 A in 357 m (1,171 ft) of water on license PL838, 5 km (3.1 mi) from Skarv and 210 km (130 mi) northwest of Brønnøysund.
“We confirmed the presence of natural gas and crude oil in the lower and middle Jurassic sandstones,” said Piotr Woźniak, president of the PGNiG management board.
“We took cores and samples of reservoir fluids and performed detailed geophysical logging, which allowed us to determine the preliminary size and assess the quality of the reservoir. This discovery is a big success for PGNiG Upstream Norway, which is operator for the license,” he added.
According to the Norwegian Petroleum Directorate (NPD), the initial well encountered an 85-m (279-ft) oil and gas column in the Fangst and Båt groups, of which around 60 m (197 ft) were sandstones with mostly good reservoir quality. Well 6507/5-9 A penetrated a 65-m (213-ft) oil and gas column in the same groups, of which 45 m (147 ft) were good-quality sandstone reservoir.
Early analysis suggests 3-6 MMcmoe recoverable, according to the NPD.
“It is very probable that the new field will be tied back to the Skarv FPSO, owned partly by PGNiG, which can have a positive impact on the profitability of the Skarv project,” Woźniak said.
“Thanks to the new discovery, we will increase our own production on the Norwegian continental shelf, where we want to produce 2.5 bcm of natural gas annually after 2022.”
The Deepsea Nordkapp will relocate to Norwegian Sea license 093 for appraisal drilling on the Draugen field, operated by OKEA.
