SPECIAL REPORT: Study evaluates viscosity prediction of crude blends

Transporting crude oil blends via pipeline requires careful estimation of their viscosities.Crude transportation often requires that different crude oils be blended and transported through the same pipeline. Intentionally diluting heavy crudes by adding less viscous oil also increases the efficiency of pipelining heavy oils. Solvents injected into the reservoir for well cleaning, stimulation, fracturing and, less frequently, miscible displacement may also remain in the crude during shipment.A mixture’s viscosity as a function of composition is extremely complex.1 Theoretical considerations have offered little help in explaining these complexities. Attempts such as McAllister’s...
