The well was\r\ndrilled practically vertical down to ca 3139 m, ca 140 m below the 13 3/8"\r\ncasing shoe, and deviated from this point. The drilling of the well was not\r\nperformed within the plan due to lost time as a consequence of bad weather,\r\nsteering and building angle in 12 1/4" hole section, extended logging,\r\nextended well and equipment failure. The well was drilled with pre-hydrated\r\nbentonite, seawater and bentonite sweeps down to 1170 m, with ANCO 2000 mud\r\nwith 3.4 to 5.2% glycol from 1170 m to 3766 m, and with a KCl/polymer mud\r\nsystem from 3766 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eOil was proven by MDT fluid sampling in a\r\nthin sand bed at 3797.5 m (3756.2 m TVD) above the main Brent Group reservoir.\r\nThe Bathonian age of these sand beds imply that they belong to the upper part\r\nof the Brent Group.
