Influence of alkyl chain length in ionic liquid based drilling mud for rheology modification: a review

Abstract The research has shown successful application of ionic liquids (ILs) as drilling fluid additives for modifying the mud rheology. Ionic are tuneable solvents comprising hundreds combination various cations and anions. cationic portion mainly comprises a side alkyl chain which plays an important role in altering properties. This review focusses on finding impact length yield point, plastic viscosity filtration properties water based at room temperature. paper also incorporates X-ray diffraction (XRD) analysis carried out by different groups confirms how intercalation between liquid Na-Bt (Sodium Bentonite) changes structure clay thus alters rheology mud. It can be concluded that act modifiers intercalating layers changing d-spacing clay. Moreover, hydrophobicity, polarity solubility play wettability dispersion behavior modify well rheological
