The discovery well 6406/2-1 had previously been\r\ndrilled on the northern segment of the B structure. The cross fault was\r\nsuspected to act as a pressure barrier between the two segments, causing\r\nvariation in fluid types. The main objective of well 6406/2-2 was to prove\r\nhydrocarbons and verify fluid contacts in the southern segment, which seemed to\r\ndiffer from the northern segment in both the nature and intensity of the\r\nseismic amplitudes. An additional objective was to investigate any differences\r\nin reservoir development between the two segments. \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 6406/2-2 was spudded 12\r\nDecember 1995 with the semi-submersible installation "Ross Rig" and\r\nTD was reached at 5367 m (5351 mTVD) 12 February 1996 in the Åre Formation. The\r\nwell was drilled water based with bentonite down to 1272 m, with KCl and glycol\r\n(ANCO 208) from 1272 to 2858 m, and with oil-based mud from 2858 m to TD. The\r\nformation tops were drilled in accordance with the prognosis, and the\r\nlithologies drilled were largely similar to those reported from 6406/2-1. The\r\nJurassic succession was encountered 5-100 m deeper than in well 6406/2-1, due\r\nto the lower structural position of well 6406/2-2. As in well 6406/2-1, well\r\n6406/2-2 proved the presence of thick reservoir sandstones in the Garn, Ile,\r\nTofte and Tilje Formations. In addition, an 8 m thick sand was drilled in the lower\r\npart of the Ror Formation. The reservoir quality showed large variations, with\r\ngenerally poor porosity in the Garn Formation, good porosity in parts of the\r\nIle Formation, generally good porosity in the Tofte Formation, and zones with\r\ngood porosity especially in the lower part of the Tilje Formation. Other parts\r\nof the Ile and Tilje Formations, as well as the sandstone beds in the upper\r\npart of the Åre Formation, were tight as a",
