The\r\nnew well was designed to test the hydrocarbon potential of the Beta structure\r\nin the southeast part of the \u003c/p\u003e\r\n\r\n\u003cp\u003eblock. The main object was Middle\r\nJurassic sandstones, secondary targets were possible Cretaceous sands, Early\r\nJurassic sandstones and sandstones within the Coal Beds.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 6506/12-3 was spudded with the\r\nsemi-submersible installation Ross Isle, 47 m from the junked well 6506/12-2.\r\nIt was spudded on 2 March 1985 and drilled to TD at 4360 m in the Early\r\nJurassic Tilje Formation (formerly called the Aldra Formation). No significant\r\ntechnical problems occurred during the operations. From 0600 hours on 15 June,\r\nduring the testing phase, the rig was on strike for 13 days. The well was\r\ndrilled with seawater/gel down to 955 m, with gypsum/lignosulphonate mud from\r\n955 m to 3831 m, and with gel/lignosulphonate mud from 3831 m to TD. The shallow\r\ngas present at 572 m in 6506/12-2 was not encountered in 6506/12-3. \u003c/p\u003e\r\n\r\n\u003cp\u003eTop Middle Jurassic Garn Formation\r\n(formerly Tomma Formation) came in at 3822 m, 80 m above the prognosis. The\r\nEarly Jurassic Tilje Formation sandstone (Aldra Formation) came in at 4147 m. Hydrocarbons\r\nwere encountered both in the Middle and the Early Jurassic sandstones, with a\r\nhydrocarbon/water contact at 4216 m in the Tilje Formation. Late Cretaceous\r\nLysing sandstones at the top of the Cromer Knoll Group (Finnvær Group) was also\r\nhydrocarbon bearing. A total of 242 m of hydrocarbon bearing sands was proven.\r\nShows were only recorded in association with the hydrocarbon bearing sections.\u003c/p\u003e\r\n\r\n\u003cp\u003eA total of 289 m core was recovered in 15\r\ncores from the Garn, Not, Ile, Ror, and Tilje Formations between 3836 and 4269\r\nm. Six RFT runs were completed in the Early - Middle Jurassic section in well\r\n6506/12-3. A total of 47 pressure tests gave reliable results. In addition,\r\nsegreg",
