Development of a Solids-Free High-Density Oil-Based Drill-In Fluid with Enhanced Interfacial Stability and Reservoir Protection

To mitigate weighting-agent settlement, reservoir pore-throat plugging, and water-sensitivity damage during deep high-temperature drilling, a solids-free high-density oil-based drill-in fluid was developed using synthetic base oil as the continuous phase and potassium formate brine as the dispersed phase. Within the fo...
