PGNiG Upstream Norway AS, Norway, has let a contract to Applied Petroleum Technology to conduct post-drilling geochemical and biostratigraphic analyses of the Shrek prospect in PL838 in the Norwegian Sea. Results are expected by the end of the month.
The license, awarded in APA 2015, lies about 210 km northwest of Brønnøysund, 5 km from Aker BP-operated Skarv field. Based on preliminary estimates, recoverable resources are 19-38 MMboe.
Two wells were drilled by the Odfjell Drilling's Deepsea Nordkapp semisubmersible drilling rig in 2019: discovery well 6507/5-9 S was drilled to 2,261 m VD and 2,285 m MD subsea, and appraisal well 6507/5-9 A was drilled to 2,134 m VD and 2,198 m MD subsea. Both wells were terminated in the Båt group in the Lower Jurassic. Water depth at the site is 357 m. The primary exploration target for both wells was Middle Jurassic reservoir rocks (the Fangst group). The secondary exploration target was Lower Jurassic reservoir rocks (the Båt group) and to delineate the discovery toward the west.
Well 6507/5-9 S encountered a total oil and gas column of about 85 m in the Fangst and Båt groups, of which about 60 m of sandstones with mainly good to very good reservoir quality. The gas-oil and oil-water contacts were encountered at 2,034 m and 2,074 m subsea, respectively.
Well 6507/5-9 A encountered a total oil and gas column of about 65 m in the Fangst and Båt groups, of which about 45 m of sandstones with mainly good to very good reservoir quality. Both the gas-oil and the oil-water contacts in the appraisal well came in at equivalent depths as the discovery well.
PGNiG expects the field to be tied back to Skarv FPSO, owned partly by PGNiG.
PGNiG is operator of PL838 with 40% interest. Aker BP and DEA Norge each hold 30% interest. PGNiG Upstream Norway currently holds shares in 24 exploration and production licenses on the Norwegian Continental shelf.
