Probability Distributions for Effective Permeability of Potentially Leaking Wells at CO2 Sequestration Sites
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
Wells with defects originating from either poor completions or subsequent damage arising from chemical, thermal and/or mechanical stresses provide potential pathways for leakage of carbon dioxide (CO2) and brine from a CO2 sequestration site. This report provides a methodology for analyzing data on the frequency of occurrence of defective wells and the effective permeability of the damaged wells. The results include bimodal, log-normal distributions of the effective permeability of wells in addition to other distributions designed to provide a measure of the likelihood of encountering a leaking well in a CO2 storage project.
