Harbour Energy plc is pleased to note operator Mubadala Energy's announcement that the Layaran-1 well has made a significant gas discovery on the South Andaman licence (Harbour 20 per cent), offshore North Sumatra, Indonesia. 

Layaran-1 is the first of a four well exploration campaign targeting the same Oligocene play as the successful Timpan-1 well drilled on Andaman II (Harbour operator, 40 per cent) in 2022. 

The rig will now move to drill the Harbour operated Halwa and Gayo wells on Andaman II.
