ABSTRACT:
Our team at ESG Solutions has provided long term seismicity monitoring for CCUS projects throughout the US and Canada. The team uses the microseismic data to update geo-mechanical model. The various projects have also demonstrated the importance of continuous monitoring during injection operations to ensure storage control and permanence. In addition, it was noted that the types of data recorded will vary over time in order to provide a consistent and cost-effective solution. The projects have demonstrated that basement seismicity increases in event density, size, and distance over time. Several passive microseismic approaches have been used to record these changes, in a downhole analog geophone array and a network of surface geophones with a sparse layout. While understanding the microseismic activity is a critical part of containment monitoring for CCUS operations, an additional piece of information that reinforces this data set is knowing the extent of the CO2 plume long term. Knowledge of the plume extent will be important to establish the long-term viability of a storage facility and the expected long term storage permanence of the in-place CO2. This paper will present a combined, cost-effective solution through the additional use of surface based Streaming Potential, Scatter Field Controlled Source Electromagnetics (S2CSEM). The S2CSEM method can be periodically deployed through the life of the storage facility to image the plumes horizontal extent. The scatter field method can also detect streaming potential changes over shorter periods of time, by changing the CO2 injection rate over a 24-48 hour period. Using both microseismic and CSEM to delineate the CO2 placement allows operators to understand what seismic activity is related to induced stress from CO2 injection and natural stress for the area. The combination of these methods will also provide understanding of capacity limitations and storage permanence at a facility. This knowledge will further help with governmental acceptance of the proposed CCUS solutions provided by the industry.
