The new RHADIANT ultra-high temperature non-aqueous drilling fluid system eliminates drilling fluid product degradation, prevents wellbore control issues, and provides a thin filter cake for enhanced logging conditions. Unlike conventional non-aqueous drilling fluids, the RHADIANT system prevents barite sag and stuck pipe. The drilling fluid system maintains a stable rheological profile and extreme temperature stability during prolonged static conditions throughout well construction and openhole logging, with little maintenance required. Ultra-thin and slick filter cake deposits and the stable rheologies clear the path for logging, casing, and cementing operations, thus enabling accurate perforation placement, optimized completions, and quality reservoir characterization.
