Cooper Energy Ltd., Adelaide, has processed first gas through its new Athena plant in the Otway basin of western Victoria near Port Campbell.
The company said the milestone was achieved in December when first gas from offshore fields at Casino, Henry, and Netherby was introduced to the Athena plant.
This followed the successful cutover of the pipeline from the previous Iona gas plant to Athena which was completed on schedule earlier in the month.
First gas sales from Athena began just before Christmas.
Ramp up of gas supply to, and processing through Athena has continued reaching current rates of 28 terajoules/day.
Cooper is operator of the project with 50% interest. Mitsui E&P Australia and Peedmulla Petroleum each have 25% interest.
