Merits of pressure and geochemical data as indicators of CO2/brine leakage into a heterogeneous, sedimentary aquifer

This study assesses the merits of pressure data and geochemical data as indicators of a combined CO2/brine leakage into a heterogeneous, sedimentary aquifer. We simulate the changes in three aquifer responses (pressure, total dissolved solids (TDS), and pH) due to CO2/brine leakage at an abandoned well with an uncertain location and hypothesize that these changes can only be observed from a single shallow monitoring well, mimicking the low...
