Tap added the Woollybutt South development has been completed with the Woollybutt-4H well ready to start production.
Production from the field is expected to be about 12,000 barrels of oil per day when all wells are producing to the Four Vanguard.
The Four Vanguard was shut down last month after free hydrocarbon gas was detected onboard the vessel.
The Woollybutt South Development ties in the Woollybutt-4H development well that was drilled and completed in 2007.
Incorporating the Woollybutt-4H well will assist in reaching ultimate reserves of about 40 million barrels of oil, of which 29MMbbl have been produced to date, Tap said.
The Woollybutt partners are Tap Oil 15%, Eni (operator and 65%) and ExxonMobil 20%.
