Microseismic Monitoring at the Farnsworth CO2-EOR Field

The Farnsworth Unit in northern Texas is a field site for studying geologic carbon storage during enhanced oil recovery (EOR) using CO2. Microseismic monitoring essential risk assessment by detecting fluid leakage and fractures. We analyzed borehole microseismic data acquired CO2 injection migration, including denoising, event detection, location, magnitude estimation, moment tensor inversion, stress inversion. detected located two shallow clusters, which occurred increasing pressure. clusters were also featured large b values tensile cracking tensors that are obtained based on newly developed inversion method single-borehole data. inverted fields at the showed deviations from regional field. results provide evidence responses to CO2/fluid migration.
