One of the core principles of wellbore strengthening is stress redistribution. When drilling mud or specialized plugging materials enter fractures, they create a mechanical seal, preventing further fluid invasion. This process alters stress distribution around the wellbore, making it more resistant to pressure changes. RWSS incorporates advanced sealing agents and wellbore-compatible materials to enhance fracture resistance and maintain stability. These materials help prevent lost circulation by sealing microfractures effectively and reinforcing weak formations without compromising drilling performance.
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.
