How can you prevent wellbore instability?
Wellbore instability is a common and costly problem in drilling engineering, affecting the safety, efficiency, and quality of drilling operations. It occurs when the rock formation around the wellbore fails due to mechanical or chemical stresses, resulting in wellbore collapse, hole enlargement, stuck pipe, or lost circulation. To prevent wellbore instability, you need to understand the factors that cause it and apply appropriate design, monitoring, and mitigation strategies. Here are some tips to help you prevent wellbore instability in your drilling projects.
