ZERT Task 3: Measurement and monitoring techniques to verify storage and track migration of CO2
ZERT Task 3 Goal
To develop reliable techniques to demonstrate storage effectiveness and quantify migration out of the storage formation and release rates at the surface.
ZERT Task 3 Overview
A combination of surface and subsurface methods will be developed for verifying storage effectiveness. Specifically, for surface monitoring we will investigate deployment and sensitivity of eddy-covariance methods, flux chamber measurements, and soil gas sampling. We will continue to support and conduct the ZERT shallow-release field test, coordinated with all of the ZERT partners, to develop, evaluate, and optimize the methods.
All assessments will be made in the context of quantifying “significant” releases from the storage structure, e.g., those that would compromise the effectiveness of geologic storage or cause unacceptable environmental impacts.
