Time-lapse seismic monitoring of enhanced oil recovery (EOR) programs has been described by several authors over the last 15 years. Advances in equalization techniques have allowed legacy data (in some cases 15 years prior to a monitoring survey) to be used as a baseline. Sensitivity of seismic data to subtle changes in pore composition has been notably improved with the development of dozens of new attribute analysis techniques in the last several years.

Unique to our application is the use of nonamplitude, noninversion attributes for monitoring the effectiveness of EOR in thin, shallow (less than 1000 m) carbonates. Considering the...
