The primary objective was appraisal\r\nof reservoir development in the western part of the Albuskjell field. A Danian\r\n- Maastrichtian gas condensate field had previously been confirmed by two wells\r\n(A/S Norske Shell l/6-l and Phillips 2/4-9) drilled farther east along the WNW\r\n- ESE trending structure. Secondary objectives were to investigate Danian Chalk\r\nprospect and possible deeper prospects. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eAppraisal well 1/6-3 was spudded with the\r\njack-up installation Zapata Nordic on 12 April 1974. Three sidetracks had\r\nfinally to be drilled, of which the second and deepest reached 3343 m in the\r\nLate Cretaceous Tor Formation. The first sidetrack was kicked off at 314 m\r\nafter unsuccessful fishing (lost hole opener). The second sidetrack was kicked\r\noff at 3022 m when it was realised that a core point had been missed so that a\r\nDanian porous zone and 37 m of Maastrichtian had not been cored. Lost circulation\r\nand stuck pipe led to the third side track, which was kicked off at 2995 m.\r\nFurther lost circulation problems and the discovery that there was a break in\r\nthe casing at 3140 m finally led to abandonment of the well without\r\ninvestigating the deeper prospects. The well was drilled with seawater down to\r\n417 m, with shale-trol/lignosulphonate from 417 m to 1221 m, with\r\nshale-trol/lignosulphonate and lime from 1221 m to 2500 m, and with\r\nlignosulphonate and lime from 2500 m to TD. A diesel/pipe lax pill was spotted\r\nat 314 m.\u003c/p\u003e\r\n\r\n\u003cp\u003eAs prognosed, gas was encountered both in\r\nthe Danian and Late Maastrichtian Chalk. Hydrocarbons were present from Top\r\nEkofisk at 3110 m down to an OWC at 3289.7 m in the Tor Formation. The net\r\nthicknesses were respectively 91 and 45 m. The great thickness of the Danian\r\nreservoir was in contrast to the findings from wells l/6-l and 2/4-9, where\r\nonly a thin hydrocarbon-bearing zone was present in an otherwise tight Danian. ",
