 The Environmental Protection Agency (EPA) Class VI data gathering requirements play a pivotal role in the monitoring and regulation of underground injection activities associated with geologic sequestration of carbon dioxide (CO2). This talk provides a concise overview of the key data gathering requirements essential for compliance with Class VI regulations. The EPA mandates a robust data collection process to ensure the effective implementation and enforcement of Class VI regulations. Operators involved in geologic sequestration projects must adhere to stringent reporting and monitoring protocols, encompassing geological, geochemical, and hydrological parameters. The talk will give an emphasis on what data to collect, when to collect it, and how it is used. Data to be discussed includes discussion of wireline logging, coring, core testing, surface sampling, and water well sampling; remote sensing data including geophysical surveys, micro-seismic and VSPs; mechanical integrity testing such as cased hole bond logs, EM flux tools; and finally continuous data monitoring of temperature, strain, noise and annulus pressures.
