This well was the\r\nfourth well on Smørbukk South, and it was a joint well between licenses PL 091\r\nand PL 094. The primary target for the well was sandstones in the Middle-Early\r\nJurassic age Halten Group (present nomenclature: Fangst and Båt Groups). The\r\nwell location was chosen so that the Tomma I Formation (Garn Formation) was\r\nexpected to be hydrocarbon bearing with hydrocarbon/water contacts in the Tomma\r\nIII - Aldra Formations (Ile - Tilje Formations).\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 6406/3-3 was spudded with\r\nthe semi-submersible installation Dyvi Delta on 4 August 1986 and drilled to TD\r\nat 4416 m in the Early Jurassic Åre Formation. Operations went without\r\nsignificant incidents and were finished twenty days ahead of schedule. Only\r\n5.2% rig time was registered as down time. The well was drilled with\r\nseawater/hi-vis pills/bentonite down to 1070 m, with gypsum/polymer mud from 1070\r\nm to 2320 m, with gypsum/lignosulphonate/lignite mud from 2320 m to 3936 m, and\r\nwith lignosulphonate/lignite/Anco resin mud from 3936 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe top of the reservoir came in at 3933\r\nm, 49 m deeper than prognosed. Cores showed poor - medium visible porosity and\r\ngood to poor oil shows from the top and down to ca 3955 m (ca 3925 m TVD MSL).\r\nThe oil/water contact was thus almost 65 m higher than the other holes in the\r\nBeta structure. RFT-data indicated that the rest of the Fangst and Båt Groups\r\ncontained water. Weak shows were however recorded on sidewall cores in the\r\ninterval 4210 m to 4262 m in the Ti1je Formation, while weak shows were\r\nrecorded on well site cuttings all through Middle - Early Jurassic down to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eA fixed offset VSP with the source 2.6 km\r\nnorth of the location was shot in order to explain the surprising and negative\r\nresults of the well.
