Lubricity performance of non-ionic surfactants in high-solid drilling fluids: A perspective from quantum chemical calculations and filtration properties

Quantum chemical calculations and mud filtration analysis were used to assess the performance of three types of non-ionic surfactants as lubricating additives in synthetic-based drilling mud (SBM) contaminated with drilled solids. High solid contaminants can have an impact on mud lubricity and can c...
