PGNiG Upstream Norway expects to develop its small Shrek oil and gas discovery via tie-back to the nearby floating production, storage, and offloading vessel on Skarv field in the Norwegian Sea.
The Polish Oil & Gas Co. subsidiary operates the 6507/5-9 S wildcat and 6507/5-9 A appraisal sidetrack in 357 m of water 5 km south of the Skarv FPSO.
The discovery well encountered a total oil and gas column of about 85 m in the Middle Jurassic Fangst group, the primary target, and in the Lower Jurassic Bat group, the secondary target. About 60 m of sandstone had good to very good reservoir quality.
The well encountered the gas-oil contact at about 2,034 m below surface and oil-water contact at 2,074 m. The top of the reservoir is about 2,000 m below sea surface.
The westward appraisal well encountered a total oil and gas column of about 65 m in the same formations, of which 45 m of sandstones had good to very good reservoir quality.
The appraisal well encountered oil-gas and oil-water contacts at the same depths as in the discovery well.
Odfjell Drilling’s Deepsea Nordkapp semisubmersible rig drilled the 6507/5-9 S well to 2,261 m vertical depth and 2,285 m measured depth below sea surface and the 6507/5-9 A well to 2,134 m and 2,198 m on Production License 838.
Cores, logs, and fluid samples indicate 3-6 million cu m of recoverable oil-equivalent hydrocarbons. The wells have been plugged.
“It is very probable that the new field will be tied back to Skarv FPSO,” said Piotr Wozniak, president of the PGNiG management board.
Aker BP ASA operates the Skarv FPSO, in which PNGiG holds an interest.
PL 838 interests are PGNiG, 40%, and Aker BP and DEA Norge AS, 30% each.
