This technical paper discusses the friction coefficient of different water based mud by introducing different lubricant towards the mud component. The main equipment used in this research study was LEM 4] 00 lubricity tester apparatus. The standard test according to API (American Petroleum Institute) was performed to compare the relative lubricities of different lubricant additives. The lubricants compositions were typically mixed into water based mud by varying the concentration by ]0% and 20%. Three types of lubricant were used in this experiment namely commercialized ester-based lubricant, diesel, and palm oil. The friction studies were conducted between metal to metal which simulate actual case between casing and drill string. As a result, the friction coefficient values reduce as lubricant concentration increased. This experimental study revealed that adding ester based lubricant drastically drops the friction coefficient values compared to diesel and palm oil lubricants.
