parameters, an early description of mud composition and behavior could be estimated. Parameters that should be tested are: a) Specific Gravity : shows the weight of base-fluid. This will indicates the density of developed mud. b) Pour Point : shows the lowest temperature at which the base-fluid still able to flow. c) Flash Point : shows the temperature at which the fluid begins to burn. d) Kinematic Viscosity : shows the resistance of base fluid to flow under the influence gravity force. Some researches have been conducted by other researchers in order to determine these base fluid properties. Table 2 shows the comparison of glycerol, palm oil biodiesel, and some mineral oils properties.
