Seismic monitoring of CO2-EOR operations in the Texas Panhandle and southern Kansas using surface seismometers Open
Injection of carbon dioxide (CO2) into depleted oil reservoir is an advantageous tertiary recovery method as it allows for the long-term storage of CO2 in the empty pore spaces resulting from the removal of in situ pore fluid. Several inst…
