Pressure measurements taken over the target Toro reservoir section in the well indicated the well had intersected a 9m gas column separate from that drilled in the Juha-1, 2 and 3 wells.
Oil Search had failed to encounter any oil or gas shows while drilling the well through the Toro formation.
Juha-4 is 35km northwest of the Hides gas field. It follows on from the Juha-5 well, drilled in the same segment as the earlier wells.
Oil Search has a 31.5% operating stake in Juha-4, while ExxonMobil holds a 56% interest and Merlin Petroleum 12.5%.
