Detection of potential leakage pathways from geological carbon storage by fluid pressure data assimilation

•We present a methodology to detect leakages from CCS based on DA.•Fluid pressure data from the upper aquifer is assimilated.•We compare the capabilities of REnKF and ES data assimilation algorithms.•We apply normal score transform to caprock permeability fields. One of the main concerns of geologic...
