The primary\r\nobjective was to test sandstone reservoirs of Middle to Early Jurassic age in a\r\nstructurally high position on a narrow SW-NE trending horst block. The\r\nsecondary objective was to test sandstone reservoirs of Early Jurassic to Upper\r\nTriassic age. The well was planned to be drilled to 3200 m, 200 m into the\r\nTriassic.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWildcat well 6609/11-1 was spudded with\r\nthe semi-submersible installation Treasure Seeker on 19 May 1983 and drilled to\r\nTD at 3068 m in Late Triassic sediments of the Åre Formation. No major\r\ntechnical problems occurred during drilling. Operations were interrupted for 11\r\nand a half days due to a crew strike. The well was drilled with seawater and\r\nhi-vis pills to 915 m and with gypsum/polymer mud from 915 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well encountered good quality\r\nsandstone reservoirs of Early Jurassic and Late Triassic age. These reservoirs\r\nwere water bearing with minor amounts of residual hydrocarbons indicated on the\r\nlogs. The uppermost part of the sandstone interval, 2546 - 2570 m had the\r\nhighest reservoir quality encountered in the well. Porosities ranged from\r\n15-30% (20.6% average in net sand) with a net/gross sand ratio of 0.85 and an\r\naverage SW of 90%. The unit ranged from Sinemurian to Pliensbachian in age and\r\nconsisted of massive to thinly bedded, very fine to fine grained sandstones\r\nwith interbeds and stringers of shale, siltstone and limestone. Below 2570 m\r\nthe sandstone units tended generally coarser grained and exhibited fining\r\nupward sequences with reduced porosity and net/gross ratio. The only recorded\r\noil show in the well was on core no 1 at 2559.7 m to 2560.9 m. No significant\r\nmud gas levels were recorded. The Late Jurassic shales and the Early Jurassic\r\ncoals and carbonaceous shales are rich source rocks for oil and gas. However,\r\nthe Late Jurassic shales are immature in the well",
