Alternative lubricant additives must have friction-reducing physicochemical properties and moderate costs comparedto those of petroleum oils before they can become widely accepted in the marketplace.The comparative analysis of several valuable friction-reducing physicochemical properties indicated that the biodiesel obtained from distilled pyrolytic oil is a suitable lubricant additive for water-based drilling fluid.Lubricant additives are added to drilling fluids to lower the drag and torque between the drill strings and rock formation.

Alternative lubricant additives must have friction-reducing
physicochemical properties and moderate costs comparedto those of
petroleum oils before they can become widely accepted in the
marketplace. Waste tire pyrolytic oil was adopted as a feedstock for
this study. Lubricant additives are added to drilling fluids to lower the
drag and torque between the drill strings and rock formation. A 56.83%
yield was obtained from the feedstock using transesterification. The
physicochemical properties of the produced biodiesel were compared
with the guidelines of the U.S. specification (ASTM Standard) and the
European specification (EN Standard). Most of the valuable friction-
reducing properties were within the standard ranges for lubricant
additives. The chemical structure of the produced biodiesel was
identified using gas chromatography-mass spectrometry (GC-MS). The
comparative analysis of several valuable friction-reducing
physicochemical properties indicated that the biodiesel obtained from
distilled pyrolytic oil is a suitable lubricant additive for water-based
drilling fluid.
