【 摘 要 】

LBNL's GEOSEQ project is a key participant in the Frio IIbrine pilot studying geologic sequestration of CO2. During During theinjection phase of the Frio-II brine pilot, LBNL collected multiple datasets including seismic monitoring, hydrologic monitoring and geochemicalsampling. These data sets are summarized in this report including allCASSM (continuous active source seismic monitoring) travel time data,injection pressure and flow rate data and gaseous sampling and tracerdata. Additional results from aqueous chemistry analysis performed by theU. S. Geological Survey (USGS) are summarized. Post injectionmodification of the flow model for Frio II is shown. Thesemodificationsare intended to facilitate integration with the monitoring data andincorporation of model heterogeneity. Current activities of LBNL's GEOSEQproject related to the Frio II test are shown, including development of anew petrophysical model for improved interpretation of seismic monitoringdata and integration of this data with flow modeling.
