Transporting crude oil inside pipeline is the common process in petroleum industry. Crude oil from difference sources has difference properties due to terrains and climates which cause the transport profile to change during the operation. In this study, computational fluid dynamics model was developed. The governing equations were employed

Chemical injection is a method which uses special chemical solutions added to water to increase the mobility and decrease the surface tension of the crude oil, and increase the viscosity of water to make it similar to the oil. A distinction between those methods is made:
