Stage 2 experiments at the Otway Project are nearly complete. The most critical part of the experiments was to force CO2 to be permanently stored in the rock pores deep underground (residual gas saturation), by injecting formation water and dissolved CO2. The injection mimics deep geological CO2 storage in the rock formation 1400 metres underground. Despite some technical challenges the injection went very well.
