Project Description

The objective of this research project is to develop and validate a program for identifying and characterizing wellbore leakage for CO2 storage applications based on analytics of well records validated with sustained casing pressure field monitoring. Major objectives include determining the nature of well defects, location of defects within the borehole, and severity of the leakage rate associated with that defect (Figure 1). Results will then be integrated with analysis of existing boreholes exposed to CO2 at study areas in Michigan, West Virginia, and Wyoming. Project results will provide predictive methods to survey, identify, characterize, and remediate wellbore integrity defects for CO2 storage applications.

Project Benefits

The primary impact of this research is to provide a practical program to address wellbore integrity issues at CO2 storage fields. The field component of this research is providing real-world analysis of the conditions of boreholes exposed to CO2 environments at locations in Michigan, West Virginia, and Wyoming. The work is developing a scientifically defensible approach to qualitatively and quantitatively assess the risk posed by wellbores exposed to CO2. Work is expanding to help provide more guidance on locating the source of the well defect, which would provide better remediation options for addressing CO2 leakage. This integrated approach brings together analysis of well information with field monitoring and testing.
