The traditional hydraulic fracturing and new thermal-expansion cracking methods employed for measuring in-situ stress require a subsequent lagging test after borehole drilling. This post-drilling often leads to deformation, cracking, and stress relea

Wellbore instability constitutes potential risks during wellbore drilling operation; these risks may cause complicated states, and in some cases, can lead to costly operational issues. In this study we present the best solution by predicting and quan

Abstract Knowledge of ground stresses is crucial for ground control activities such as the design of underground openings, selection of support systems, and analysis for stability. However, it is a known fact that far field stresses experience change
