Wellbore strengthening is a drilling technique designed to reinforce the wellbore walls, preventing drilling fluid losses and well collapse. This process involves modifying the drilling fluid or injecting materials into the formation to create a stronger and more stable wellbore. It is especially useful when drilling through weak formations or high-pressure zones where fractures can easily occur.
An Introduction to Managed Pressure Drilling (MPD) and Its Benefits
The main goal of MPD drilling is to balance the pressure in the wellbore with the surrounding formation pressure. This helps to avoid sudden pressure surges and ensures a more controlled and efficient drilling process.
