Harbour Energy plc has announced a significant gas discovery at the Layaran-1 well in Indonesia. The well is located on the South Andaman license, in which Harbour holds a 20% stake. The discovery was made during a four-well exploration campaign targeting the Oligocene play, the same play that yielded success at the Timpan-1 well on Andaman II in 2022. Following the Layaran-1 discovery, the drilling rig will now move to the Harbour-operated Halwa and Gayo wells on Andaman II.
