EXPERT-BASED DEVELOPMENT OF A SITE-SPECIFC STANDARD IN CO2 SEQUESTRATION MONITORING TECHNOLOGY
Impact/Purpose:
The proposed research will:
- Quantitatively evaluate potential monitoring strategies to select an array of strategies and guidelines for application to specific sites;
- Test the results of evaluation against the growing array of field measurements, gathered from past and current BEG (UT Austin Bureau of Economic Geology) test sites (Frio, SACROC (Scurry Area Canyon Reef Operators Committee), Cranfield), DOE partnership program, and elsewhere, especially abroad;
- Develop widespread consensus that these strategies are adequate when properly applied, and
- Compile a test/teaching set of cases for testing strategies and then train practitioners in applying the strategies to an array of sites.
Description:
The purpose of this project is to help regulators and operators alike in determining the most appropriate monitoring approaches and strategy for a given CO2 sequestration site. A monitoring strategy differs from a list of tools because it is designed as a dynamic process where the type of monitoring tool selected, type of test, and the frequency with which measurements are made changes depending on the results of the last set of measurements. The monitoring strategy should be tailored to the sequestration site and based on the extensive site characterization that is the main tool to ensure that CO2 is retained in zone. However, no guidance currently exists for the site operator or regulator to determine how to match the site with the technologies.
