Estimating reservoir permeabilities using the seismic response to CO2 injection and stochastic inversion

► Developed a Markov Chain Monte Carlo inversion tool. ► It identifies permeability models based on seismic reflection and other data. ► Algorithm's effectiveness is demonstrated with a synthetic data test. ► Test shows that key features of the permeability distribution are recovered. ► Algorithm applied to observed seismic data from Weyburn with limited success.
