Nowadays, many base fluids and additives are still widely used in drilling industries as material used in drilling <br /> <br /> fluid regardless their toxicity and cumulative impact on terrestrial, coastal, and marine habitats. Thus, the <br /> <br /> suitable candidate for development of a highly biodegradable base fluid and additive for drilling fluid with a sustainable source of supply is needed. <br /> <br /> The application of glycerol by-product of palm oil biodiesel industry in drilling fluid was carried out in this work. Glycerol, with its renewable, highly biodegradable, very low toxicity, and environmentally friendly nature, will be utilized as a new alternative base fluid for Synthetic-Based Mud (SBM) and lubricant for Water-Based Mud (WBM). Due to the poor quality of crude glycerol from palm oil biodiesel industry, it need to be <br /> <br /> purified before its physio-chemical characterisation can be tested and then formulated further. In this study, crude glycerol will be purified using H3PO4 solution to increase the purity of glycerol from about 50 % to more <br /> <br /> than 80% (Farobie, 2009). The characterization of glycerol physio-chemical properties include density, flash point, pour point, and cloud point. An invert emulsion mud then developed in the laboratory using glycerol as base oil to study the emulsion stability, rheological properties, and the effect of thermal conditioning to evaluate its suitability for oil well drilling. The effect of glycerol as a lubricant additive in Water-Based drilling fluid on <br /> <br /> the mud lubrication properties, rheology, filtration loss, and its compatibility with other additives is also <br /> <br /> evaluated as well. The preliminary tests result indicates that glycerol can be used as synthetic based mud in accordance with the API standard and also can become the reference for this synthetic based mud development and also has been proved to increase mud lubricating potential without affecting other properties of drilling fluid significantly which is very potential due to its environmentally friendly characteristics and low cost, since it may be obtained from an abundant raw material from by-product of biodiesel production.
