High-temperature drilling in deep HPHT and geothermal wells (>180–220 °C) causes thermal degradation of drilling fluids, which compromises hydraulic performance and accelerates wear of PDC and diamond-impregnated bits. This study evaluates three fluid systems – high-temperature oil-based mud (HT-OBM), thermally stabilized water-based mud (HT-WBM), and nanoparticle-enhanced synthetic-based mud (nano-SBM) – subjected to static aging in HPHT cells at 150–240 °C for 16–40 hours, followed by measurements of...
