Methodology for Assesment of Drilling Fluid Additives for Drilling of Depleted Reservoirs Using Barite-Weighted Oil-Based Drilling Fluid and Testing with Backflow Through Production Screens

Drilling through depleted reservoirs presents significant operational challenges due to potentially reduced formation pressure, increased risk of lost circulation, and potential wellbore instability. These issues create further complexities when drilling across reservoir sections where formation damage and production impairments must be minimized.
