Abstract: Blending of Crude oils is a process of mixing two or more crude petroleum components together and is done to improve the overall value or quality of the blend. The reasons vary but may be done to improve pipeline capacity, improve the value of the blend or to help a refinery improve the product yield from its processes. Blending operations can be expensive requiring pumps, meters, tanks etc. Consideration must be given to the cost of infrastructure, cost of diluent, and what measureable property will you use e.g. Viscosity or API gravity. Questions that must be answered include: How will the pay back occur? Will the value of the product be increased? Will the pipeline work more efficiently? Can you blend on someone elses behalf and charge a blending fee? Care must be taken to evaluate all the parameters because one of the blending features may cancel out the benefit initially realized. For example, if two crudes were blended to reduce the overall sulphur concentration the sum of the parts may result in more volume than the pipeline can physically handle
