The Perth-based company yesterday said current operations there are now completing the well for gas deliverability.
Lee-3 was designed to produce gas and condensate from a field discovered by the Lee-1 exploration well. It is expected to take about five days to complete and perforate the well ready for production.
The Lee-3 bottom-hole location lies about 2.5km southeast of the Linda Platform.
The Harriet JV comprises Apache Energy (operator with a 68.5% stake), Kufpec Australia (19.2771%) and Tap (12.2229%).
