The Perth-based company is using the Parker 253 rig to drill Kurnia-1, which is targeting 200 million barrels (MMbbl) of recoverable oil and 256 billion cubic feet of gas at the P50 level of confidence.

A 243km 2D seismic program started in the South Madura PSC in May, designed to mature further prospects for drilling.

At the end of the year, the Perth-based company also expects to spud a second Indonesian well located offshore North East Sumatra in the Seruway PSC, in which Cooper acquired a 22.5% stake earlier this year.

The Gurame-1 well is appraising the undeveloped Gurame gas field, located 50km from the giant Arun gas field and liquefied natural gas plant.
