No additional hydrocarbon bearing intervals were found.\r\nThe Tarbert Formation (2810 - 2903 m) was oil bearing down to 2827 m (OWC from\r\nRFT). The net pay was estimated to be 13.6 m and average water saturation\r\ncalculated to 37.9%. Average porosity was 21.2%. RFT results showed no pressure\r\ncommunication with well 30/9-4 in the Omega structure within the Tarbert\r\nFormation. Some oil shows were described in thin sandstone stringers at the\r\nbase of the Våle Formation and down into limestones in the uppermost Shetland\r\nGroup (2375 m to 2382 m). Below OWC in the Tarbert Formation, sandstones had no\r\nto weak petroleum odour and cut fluorescence down to 2880 m and brown dead oil\r\nstain and weak cut fluorescence down to 2885 m.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eTwo cores were cut in the Tarbert\r\nFormation from 2832 m to 2888 m.
