CO2CRC:reliably validating CO2 plume migration models in the subsurface

摘要

CO2 storage sites require ongoing monitoring and verification(M&V)so we can understand the behaviour of the CO2 plume and provide assurance of storage integrity.Injection of CO2 into rock formations alters their rock-fluid equilibrium.Seismic data can detect variations in the elastic properties of rocks,caused by changes in fluid saturations and pore pressure.Repetitive seismic(also known as time lapse seismic)is a powerful technology to monitor such variations.
