Otway Stage 2C Project

Project Summary

Australian saline formations have the capacity to store all of the country’s CO₂ needs, provided uncertainties are addressed. The CO2CRC Otway Stage 2C Project aims to inject up to 15,000 tonnes of CO₂ into a saline formation to demonstrate important aspects relevant to large-scale geological storage of CO­₂ in saline formations, as proposed by Australian CCS Flagships and other large-scale CCS projects around the world.

The project involves the installation of the permanent seismic array in the summer of 2014/15, the completion of injection by mid 2016 and the conduction of post-injection annual seismic surveys to monitor the plume to 2018.

The Otway Stage 2C project has three scientific objectives:

1. Detect injected CO₂ (Buttress gas) in the subsurface and ascertain minimum seismic detection limits.
2. Observe the gas plume development using time lapse seismic.
3. Verify stabilisation of the plume in the saline formation using time lapse seismic.
