Vol 2 Chapter 19: Monitoring Options for CO2 Storage
Rob Arts and Pascal Winthaegen
Abstract: In this paper an overview of various monitoring techniques for CO2 storage has been given, structured into three categories: instrumentation in a well (monitoring well); instrumentation at the (near) surface (surface geophysical methods); and sampling at the (near) surface measuring CO2 concentrations (geochemical sampling techniques). An overview of what these techniques can monitor has been provided in terms of features, events and processes (FEPs). The main categories of FEPs identified in this report are: cap rock integrity (leakage); ground movements (uplift, earthquakes); lateral spreading of the CO2 plume; and verification of mass balance. For the geophysical methods the physically measurable parameters have been provided and the effects of CO2 on these parameters are discussed and partially quantified.
