Monitoring Options for CO2 Storage
bookPart
This chapter provides an overview of various monitoring techniques for CO2 storage that is 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). Monitoring in a well within the reservoir can be of great value for determining the CO2 distribution within the reservoir, monitoring the solution of CO2 in water and calibration of other monitoring techniques. Monitoring of wells in aquifers above the reservoir can provide information regarding seal integrity and leakage. The chapter discusses the features, events and processes (FEPs) of these techniques. The main categories of FEPs discussed include 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 are provided and the effects of CO2 on these parameters are discussed and partially quantified.
