Cooper Energy is proposing an expansion of its Casino Henry Netherby development in the Otway Basin that could shore up east coast gas supply.
The proposed expansion – called the east coast supply project – has been lodged with NOPSEMA and is currently open for comment until February 25.
Cooper Energy operates the Casino Henry Netherby (CHN) development, the fields of which have been developed incrementally since 2004, with gas transported from the offshore fields, via pipeline, for onshore processing. All gas supplies the domestic market in south-east Australia.
The proposed east coast supply project aims to continue to meet the domestic demand for gas as existing CHN fields decline, by continuing to incrementally tie in nearby gas fields into existing CHN infrastructure. Hydrocarbons from these fields would be transported to shore via the existing CHN pipeline and processed at the existing Athena gas plant situated roughly 6km inland from Port Campbell.
Specifically, the east coast supply project comprises up to eight gas field tie-in opportunities with up to 15 wells, infield flowlines and manifolds. These opportunities include:
- confirmed resources at Annie and Henry fields
- prospective resources at Elanora, Heera, Juliet, Nestor, Isabella, Pecten East.
