ConocoPhillips Australia has confirmed a natural gas discovery at its Essington-1 exploration well in the Otway Basin, marking the first find in the basin since 2021.
The well, located in permit VIC/P79 about 53 km offshore Port Campbell and 12 km from existing production infrastructure, encountered hydrocarbons in both of its target formations, the Waarre A and Waarre C reservoirs.
Early analysis from logs and wireline data indicates a 62.6-metre gross hydrocarbon column in the primary Waarre A reservoir and a 33.2-metre column in the secondary Waarre C.
The wel was spudded on November 1 by Transocean’s Transocean Equinox semi-submersible drilling rig.
“The Essington-1 well is the first discovery in the Otway since 2021 and is a promising start to ConocoPhillips’ exploration activities in the region. The initial results are encouraging, and we look forward to continuing drilling our second exploration well in December,” said Jan-Arne Johansen, President, ConocoPhillips Australia.
The company said further technical work will assess potential flow rates, the reservoir’s recoverable resources and the commercial viability of a future development. Essington-1 will be plugged and abandoned after operations are completed, in line with its approved environment plan.
