An apparatus was selected and modified for formation damage studies at elevated temperatures and pressures. Procedures were developed to ensure reproducible results and are discussed in detail. Initial tests demonstrate a decline in formation damage with increased temperature when clear brine systems are used. The technique may be applicable for selection of drilling and completion fluids for field use.
