Block 6507/5 is located in the NW corner of the\r\nNordland II, which is a geological province separated from the Halten and Dønna\r\nTerrace by the deep Træna Basin to the east. The main objective of the well was\r\nto test the hydrocarbon potential of the Middle-Lower Jurassic shallow marine\r\nsandstones. The prognosed formation pressure was supposed to follow the general\r\nbehavior of the Haltenbanken Region, where a pressure regression might be\r\nexperienced towards the Base Cretaceous at 4080 m. The objective Middle\r\nJurassic sandstones were expected to exhibit a potentially high level of\r\noverpressure. No shallow gas warnings were given. \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 6607/5-2 was spudded on 7\r\nAugust 1991 by the semi-submersible installation "Dyvi Stena" and\r\ncompleted 16 November 1991 at a total depth of 4684 m in intrusive rocks within\r\nthe Upper Cretaceous Kvitnos Formation. Bentonite mud was used to 1225 m, water\r\nbased KCl polymer mud was used from 1225 m to TD. There were no lost time\r\naccidents. The 523 m of water depth made this well the deepest well to date\r\ndrilled on the Norwegian continental shelf. The well bore was maintained in\r\nexcellent conditions over the entire well. Only 0.9 day of hole instability NPT\r\nwas accumulated for this well. Throughout the well, immediate mud weight\r\nincrease was made to counter excessive drag thus contributing to hole\r\nstability. During logging at TD, RFT results indicated a maximum pore pressure\r\nof 1.51 g/cm3. Following open hole logging of the 8 1/2" section, on\r\nrequest, the hole was plugged back and sidetracked at 3998 m RKB to permit a\r\ncore cutting from 4161 - 4188.5 m in the Nise Formation sand, prior to resuming\r\nplug and abandon. No fluid samples were taken. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well did not penetrate the primary\r\nobjective of Middle-Early Jurassic sandstones.
