  • Wellbore history

    Well 6507/5-9 S was entered with the semi-submersible rig Deepsea Nordkapp on 30 August 2019 and drilled to TD at 2317 m (2293 m TVD) in the Early Jurassic Åre Formation The well was drilled as a deviated S-shaped borehole with an inclination of 17° and 305-azimuth through the reservoir interval. The well was drilled down to 456.5 m with seawater and sweeps, from 456.5 to 1103 m with seawater, hi-vis, and KCl/Glycol water-based mud , and from 1103 m to TD with Innovert oil-based mud.
    The primary target, top Garn Formation in the Fangst Group, was penetrated at 2033 m (1988.5 m TVD MSL) and consists of well sorted massive sandstone. The Not Formation was encountered at 2061 m (2015.8 m TVD MSL) and consists of argillaceous and silty sandstone. The Tilje Formation was encountered at 2072.5 m (2026.8 m TVD MSL) and Åre Formation at 2086 m (2039.7 m TVD MSL). The secondary target, Lower Tilje/Åre Formation, was encountered at 2243 m (2190.2 m TVD MSL) where the formations consists of interbedded sandstone, siltstone, and claystone with high content of coal beds representing an Intra Åre coal unit. Well 6507/5-9 S encountered in the reservoir section a 45 m gross gas column and a 39 m thick oil column in an extensive sandstone package with mainly good to very good reservoir quality of Fangst and Båt groups of Jurassic age. The gas-oil contact (GOC) was encountered at 2079 m (2033 m TVD MSL) determined from formation pressure gradient analysis and the oil-water contact (OWC) at 2119.6 (2072 m TVD MSL). However, the neutron-density logs crossover indicated GOC at 2074.9 m (2029.1 m TVD MSL). The reservoir hydrocarbon zone Net/Gross ratio was calculated to be at 78.2%.
    Three core runs with a total of 126 m of core was cut through the hydrocarbon bearing rock sequences and into the water wet zone in the primary target. A total of 121.7 m partly unconsolidated and in general weak core material was recovered to surface. MDT pressure survey and fluid sampling were performed. MDT fluid sample were taken at 2038 m (1993.8 m TVD MSL, gas), 2074 m (2028.25 m TVD MSL, gas), 2088.9 m (2042.6 m TVD MSL, oil), 2116.5 m (2069 TVD MSL, oil) and 2121.6 m (2073.83 m TVD MSL, water). The second target interval was not hydrocarbon bearing and co coring was performed. After the discovery, it was decided to drill the 6507/5-9 A sidetrack to verify extension of hydrocarbon bearing reservoir.
    The well with its sidetrack was permanently plugged and abandoned on 27 September 2019 as a small discovery with potential for development.
    Testing
    No drill stem test was performed.
