Drilling proceeded\r\nwithout significant problems. The well was drilled with spud mud down to 454 m,\r\nwith gel mud from 454 m to 1165 m, with KCl/Polymer mud from 1165 m to 2769 m,\r\nand with ligno/lignosulphonate mud from 2769 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe well consisted mainly of claystones\r\nin the Tertiary and Cretaceous sections, with the exception of sand development\r\nin the Utsira Formation (Miocene), and an Early Oligocene sand development\r\n(1288 - 1323 m). The rest of the well, the Jurassic and Triassic sections, was\r\nmainly composed of alternating claystone/sandstone sequences. Top Statfjord was\r\nencountered at 2414 m.The Statfjord and Lunde Formations were oil filled down\r\nto a common OWC at 2610 m based on pressure gradients. Strong shows on cores continued\r\ndown to 2622 m, below this depth the shows became weak and spotted. Apart from\r\nthis oil shows, of variable quality, started in silty claystones at 2180 m in\r\nthe Late Cretaceous and continued down to 2755 m in the Lunde Formation.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eA total of 19 cores were taken in the\r\ninterval 2396 - 2643 m in the Jurassic (Dunlin- and Statfjord Formations) and\r\nthe Triassic sequence (Upper Lunde Formation).
