Appraisal/development well and sidetrack with surface location at Cladhan Field drill centre. Main hole deviated NNE to test Cladhan Sequence 2 Sandstone (Kimmeridge Clay Formation, J66 sequence) in channel-fill defined by amplitude anomaly. Well encountered 188 ft gross, tightly cemented sandstone at 10,664 ft (9,184 ft TVDSS) with possible oil saturation in two thin sands (6.3 net). Well re-entered after drilling Cladhan development wells and deviated SE to drill sub-horizontal Cladhan Sequence 1 water injector (W1), extended as appraisal of oil channel sand encountered in toe of P2 producer. Sequence 1 injection target drilled 10,635–12,709 ft, with oil in two Sequence 1 sands at appraisal objective from 13,626–13,811 ft and 14,251–14,345 ft.
