Project Description

This project is evaluating how subsurface strain measurements can be used to improve the assessment of geomechanical properties and advance an understanding of geomechanical processes that may present risks to subsurface carbon dioxide (CO2) storage systems. Clemson University is designing and building instrumentation for measuring the in-situ strain and evaluating the performance characteristics relative to the existing state of the art instrumentation. Data acquired will be used to develop analyses for characterizing the strain field associated with injection near the well and in the vicinity of critical features, such as contacts and faults.

Project Benefits

This project evaluates how subsurface strain measurements can be used to improve the assessment of geomechanical properties and advance an understanding of geomechanical processes that may present risks to subsurface CO2 storage systems. This effort will improve the reliability of theoretical models, thereby assisting in storage site monitoring decisions and risk assessment activities. Specifically, the project is developing and demonstrating innovative instrumentation that will be field tested, and further developing theoretical techniques for characterizing the strain field resulting from injection.
