The transportation of a heavy crude oil of 12.71° API was studied by dilution with different hydrocarbons (crude oils and their distillates) in blending ratios from 95/5 to 5/95 vol % HCO/diluent. The target of the maximum viscosity value of the blends was fixed at 300 cSt at 37.8 °C to allow the crude oil to be transported. The evaluation was carried out to transport in a 10 km pipeline 10 000 BPD of heavy crude oil with the different diluents. As expected, the viscosity of the blends is reduced when the diluent is lighter. The highest required amount of diluent was for Maya crude oil (64.2 vol %) and the lowest was for naphtha from Isthmus crude (19.7 vol %) to meet the required maximum viscosity. Capital expenditures resulted in 2.7 and 3.5 MMUSD for pipeline diameters of 4 and 6 in., respectively. The lowest operation expenditures (53.22 USD/bbl) were for dilution with straight-run heavy gasoil from Isthmus crude oil. This diluent also presented the lowest total blending cost. The contribution of pumping, maintenance, and labor costs was marginal, with less than 1% with respect to the total blending cost.

“…Despite the significantly lowered chilling point (the pour point onset temperature) of the West Kazakhstan product mix due to the natural depressor effect of HMW components of heavy oils in relation to depositing wax crystals, the problems of the flow fluidity at low temperatures after a long shutdown of the section did not allow abandoning the hot pumping method [3,4,5].…”

This paper presents results of studies of the problem to describe the nature of oil flow at low temperatures and shear velocities for prediction of flow fluidity and determination of the parameters of a cold start of an oil pipeline after an extended downtime. Analytical and experimental studies have been carried out, which include a review of rheological test data from earlier studies available in the literature and an analysis of empirical relation obtained with the rotational viscometry method. More specifically, the existence of a zone of viscosity anomaly for low-paraffin and heavy oils has been proved on the basis of laboratory test data of model mixtures of commercial crude oils and their weighted samples. The necessity has been substantiated to create more adaptive rheological models which fit the total curve of oil flow, including the zone of viscosity anomaly in the transient state of cold start, this zone manifesting itself when reaching a certain temperature, even for low-paraffin oils. Based on the results of this work, the most advance multi-factor rheological models have been identified for description of the total shape of the rheological curve in a wide range of temperatures and velocities.
