Vertical exploration well on Andromeda North; fault block on Variscan faulted anticline with closure below intra-formational top seal within lower Westphalian A. Underlying Westphalian A and Namurian C fluvial sandstone objectives at 10,800–11,300 ft, with possible secondary targets in Namurian A/B. Well encountered significant gas column in good quality Westphalian A sandstones in a 70.9 ft gross section, with a shallower gas-water contact than anticipated. Formation pressure data confirmed mobile gas. Estimated GIIP at lower end of pre-drill expectations.
