The Bream structure is a domal (salt-induced) anticline.\r\nThe pay zone is the Middle Jurassic sands at a sub-sea depth of 2377 m (7800\r\nfeet). The 17/12-1R well was drilled on the crest of the Bream structure. Here\r\nLate Jurassic black marine shales with excellent source rock potential overlie\r\na 156 m thick Early - Middle Jurassic sequence of interbedded sands and shales\r\nin which net sand thickness totals 38 m. Two 8 m thick sands near the top of\r\nthe Middle Jurassic section tested oil. The Upper sand was oil saturated and\r\nthe lower sand contained an oil/water contact between 2337.2 m and 2344 m (2310.4\r\nm and 2317 m MSL). Two overlying sands, however, contained only water, which\r\nindicates that individual sands possess independent hydrodynamic\r\ncharacteristics and, therefore, probably are lenticular and laterally\r\ndiscontinuous. It was expected that on the flank of the structure potential\r\nreservoir sands would be thicker, and additional sands would be encountered.\u00A0 \u003c/p\u003e\r\n\r\n\u003cp\u003eHence, primary objective was Middle\r\nJurassic sands. Estimated top and thickness of the sand was 2313 m (7590 ft)\r\nand 91 m (300 ft), respectively. Planned TD was at 2591 m (8500 ft), 120 m into\r\nTriassic sediments\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 17/12-3 was spudded with the\r\nsemi-submersible installation Nortrym on 12 December 1979. Due to technical\r\nproblems it was re-spudded 19 December. The well was then drilled without\r\nsignificant problems to TD at 2730 m in m in the Triassic Skagerrak Formation. \u003c/p\u003e\r\n\r\n\u003cp\u003eTop Cretaceous (Tor Formation) came inn\r\nat 817 m, 28 m deeper than prognosed.
