Wellbore historyGeneralWell 6407/7-9 A was drilled to test the Njord North Flank 3 prospect about 6 km north of the producing Njord Field in the Norwegian Sea. The primary objective was to prove hydrocarbon potential in the Early-Middle Jurassic Tilje and Ile formations. The secondary objective was to test the hydrocarbon potential in the Åre Formation.Operations and resultsWildcat well 6407/7-9 A was kicked off on 20 September 2016, from 1110.7 m in the 13 3/8" casing in primary well 6407/7-9 S. The sidetrack was drilled with the semi-submersible installation Songa Delta to TD at 4960 m in the Early Jurassic Åre Formation. Operations proceeded without significant problems. The well was drilled with XP07 oil based mud from kick-off to TD.Gas with traces of oil-range hydrocarbons was encountered in thin intra-Lange Formation sandstones in the interval 3644 to 3780 m. Top Ile Formation was penetrated at 3992 m (3365.1 m TVD). The Ile Formation had shows in the top from 3998 to 4008 m, but no mobile hydrocarbons were proven. A 195-metre TVD gas column was encountered in the Tilje Formation, from formation top to formation base, and a 140-metre TVD gas column from top Åre Formation to ca 4888 m (4097 m). The reservoir properties in the reservoirs are poor to moderate. No true oil-water contact was observed, only down-to contacts. Weak oil shows (fluorescence) are described below 4888 m in the Åre Formation as deep as 4977 m.No cores were cut. MDT fluid samples were taken in the Ile Formation at 4326.1 m (water), and in the Tilje Formation at 4659.4 m (gas condensate). Isotubes to collect further gas, including in the Lange Formation, proved to contain only air and no formation gas.The well was permanently abandoned on 16 October 2016 as a gas discovery.TestingNo drill stem test was performed. -
