Molecular design of oil-based drilling fluid emulsifiers by Monte Carlo simulation

Monte Carlo simulation is applied to study the miscibility among hydrophobic phase hexadecane and hydrophilic phasewater. The research results show that the compatibility between the aliphatic chains of oleic acid, linoleic acid and ricinoleic acid with hexadecane is superior to other aliphatic chains, and the compatibility between water and hydroxy group is better than other hydrophilic groups.
