This final report summarizes the work done on Utah FORGE project 2-2404. The project aimed to develop a methodology integrating alternative well bore and core-based methods and reservoir-scale focal mechanisms (FM) to better estimate the reservoir stress at FORGE. The project objectives were to apply anelastic strain recovery, differential strain curve analysis, fracture mechanics analysis of drilling-induced cracks and combined them with other wellbore-based sources of stress data available from FORGE (DFIT, flowback, image logs of injection intervals, injection pressure record) to better estimate the near- wellbore stress distribution. Then, the resulting stress field would be inverted together with the reservoir-scale in-situ stress data obtained from a novel interpretation of focal mechanisms to characterize the stress and pore pressure distribution within the reservoir. Integrating these multiple sources of stress data would yield a more reliable estimate of the stress state at the km-scale for use in different FORGE reservoir development activities. The developed methodology can readily be applied to future EGS projects.
