Tryfan exploration well. An Eocene stratigraphic pinch-out with Frigg Sandstone (primary) and Dornoch (secondary) objectives. A strong amplitude response in a major Frigg channel system extending eastwards into the Nuggets 1 Frigg submarine channel/fan system. Well encountered an 18 ft gas column at top Frigg (4,746 ft), with net pay/gross of 1.0, average porosity 34% and Sw 13%. Deeper Frigg sands and Dornoch (5,102 ft) were water-wet.
