Nowadays, mineral oil is still widely used in drilling industries as synthetic oil-based mud (OBM) regardless its toxicity and cumulative impact on terrestrial, coastal, and marine habitats. Thus, the suitable candidate for <br /> <br /> development of a highly biodegradable OBM with a sustainable source of supply is needed. Glycerol are <br /> <br /> renewable, highly biodegradable, has very low toxicity, environmentally friendly, and can be produced as per industry demand. <br /> <br /> The development of an OBM from glycerol was carried out in this work. Glycerol used in this study, which is by-product of palm oil biodiesel industry, is a new alternative for OBM that is potential to be developed locally, environmentally friendly, and able to meet the standard requirement of OBM. Due to the poor quality of crude glycerol from palm oil biodiesel industry, it need to be purified before its physio-chemical characterization can be tested and then formulated as base oil of synthetic OBM. In this study, crude glycerol will be purified using <br /> <br /> H3PO4 solution to increase the purity of glycerol from about 50% to more than 80% (Farobie, 2009). The characterization of glycerol properties include chemical compound, density, flash point, pour point, and cloud <br /> <br /> 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. <br /> <br /> The preliminary tests result indicates that glycerol can be used as synthetic OBM in accordance with the API <br /> <br /> standard and also can become the reference for this synthetic OBM development which is very potential due to <br /> <br /> its environmentally friendly characteristics and since it may be derived from the abundant and low cost raw materials from by-product of biodiesel production.
