Vertical exploration well on Lyon prospect, with Balder T50.1 sequence sandstones defined by stratigraphic pinch-out at 12,100–12,800 ft, with dip to NW, and strong seismic amplitude and Class III AVO anomalies showing conformable cut-off. Well encountered 144 ft gross Balder T50.2/T50.1 siltstone/claystone with low gas saturations corresponding to seismic anomaly at 12,028–12,306 ft (11,921–12,199 ft TVDSS). No sand development in Flett T45.3 secondary target.
