Session 26. Oral Presentation for: Time-lapse borehole seismic imaging of CO2 plume migration in a heterogeneous saline aquifer: Stage 4 CO2CRC Otway Project

Presented on 21 May 2026: Session 26 The CO2CRC Otway International Test Centre in Victoria is a field laboratory for testing monitoring technologies for safe, effective geological carbon storage. Stage 4 of the Otway Project evaluates continuous and time-lapse seismic monitoring of a controlled carbon dioxide (CO2) injection into a heterogeneous saline aquifer at about 1.5 km depth. Ten kilotonnes of supercritical CO2 were injected via an existing well reperforated roughly 50 m above the previo
