CGG has started its Gippsland ReGeneration 3D reprocessing project in Australia’s premier Gippsland Basin, offshore southeast Australia. The project will offer the industry the highest-resolution 3D seismic data available in what CGG calls an "extremely prospective" area.
Historically, imaging the Gippsland Basin’s shelf break and numerous submarine channels has proven extremely challenging. CGG says it will apply its latest high-end technology and workflows, including advanced de-multiple and high-frequency FWI, to delivery "significant" reservoir imaging improvements, to reveal new potential deep reservoir targets and extensively improve understanding of the basin.
To date, the Gippsland Basin has produced over 4 billion bbl and 7 Tcf of gas, sourced from thick coal seams formed during the Paleocene to Eocene, and trapped in late Tertiary, inversion-formed, compressional structures. The first major offshore discovery was made over half a century ago and there is still tremendous opportunity for new discoveries and developments, CGG says.
Mark Richards, Senior Vice President, Eastern Hemisphere, Multi-Client & New Ventures, CGG, said: “CGG sees the Gippsland Basin as an exciting opportunity to show how its leading-edge seismic imaging technologies can enable the industry to breathe new life into a mature basin. With its well established infrastructure and under-developed resources, we believe this high-end reprocessing project has the potential to regenerate the basin and offer a solution to the projected shortfall in Australia’s East Coast gas supplies.”
