The physicochemical characteristics of the crude oil and its flow behaviour is an essential and is a significant part of the flow assurance study. One of the critical issues in flow assurance mana-gement is the restrictions to the fluid flow ability caused by the formation of deposits in well tubing and crude oil pipeline systems. In this paper, investigation results on the behaviour of waxy crudes in Malaysian oil basins are presented. Wax Appearance Temperature (WAT), Total Acid Number (TAN), pour point, wax content, water by distillation, density, API gravity, kinematic viscosity, SARA content, heavy metals, carbon number distribution and hydrocarbons recovery of three waxy crude oil samples from different field locations named as PN01, PT03 and SP01 were carried out. Results show that crude oils SP01, PN01 and PT03 have wax content between 20.50 to 37.10 and WAT in the range of 43.40 to 69.90°C. The presence of heavy metals in the analysed crude oils were found to be relatively low in concentration. The crude oils PT03 and PN01 have higher mole percent of carbon distribution between C20 and C40 compared to crude oil SP01. Crude oil PT03 and PN01 also recorded higher content of wax which results in higher WAT compared to crude oil SP01. By studying the crude oil characteristics from different oilfield locations, better understanding on the characteristics of Malaysian waxy crude oils is achieved.
