Abstract
Over the years, environmental issues surrounding the use of conventional diesel oil-based drilling fluids have been on the increase. This has forced companies to develop drilling muds which are safer and friendlier to the environment. In this study, oil was extracted from neem (Azadirachta Indica A. Juss) seeds for use as the base fluid for the drilling fluids to be formulated. To determine their suitability as drilling fluids, the physiochemical properties (kinematic viscosity, pour point, aniline point, flash point and specific gravity) were tested. The Hydrometer was used to determine the specific gravity, the KV-8 temperature-controlled bath was used to determine the kinematic viscosity. The result of the physiochemical analysis of Neem oil (Kinematic viscosity of 51.93 Cst., the pour point temperature of −6°C) is in good agreement with the available literature on base fluids that are required for drilling fluids formulation, and thus qualify to be used as base oil in drilling fluids.
