Drilling went without\r\nproblems, but the prospect was intersected 50 m away from where it was decided,\r\nin north-eastern direction. The well was drilled with spud mud down to 963 m\r\nand with KCl/polymer mud from 963 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eTop Brent Group, Tarbert Formation was\r\npenetrated at 2874 m. Moveable oil was confirmed by logs, RFT pressure\r\ngradients and tests in sandstones in the Ness and Etive formations from 2908 m\r\n(2880 m TVD MSL). The OWC was not clearly defined, but indicated from RFT\r\npressure gradients to be at 2935 m (2907 m TVD MSL). The Oseberg Formation was\r\nwater bearing. The Cook Formation had good oil shows but it was tight and\r\nimpossible to test.
