The blending of Middle East heavy crude oil with light crude oil or with one of its distillates, such as kerosene or diesel, as diluents was conducted over the entire range of weight fractions at 20 °C and atmospheric pressure. The heavy oil viscosity was decreased from 4000 to 500 cP, representing an 88% reduction. Heavy crudes account for a large fraction of the world’s potentially recoverable oil reserves. The viscosities of those crudes at room temperature vary from 100 mPa s to more than 10 5 mPa s. Generally, crude oil with viscosity <400 mPa s is the classical maximum desired pipeline viscosity [6], [7], [8]. For instance, if you mix an oil with a viscosity grade of 68 and an oil with a viscosity grade of 22, the proportions needed to attain a viscosity grade of 32 are 65 percent of the oil with a viscosity grade of 68 and 35 percent of the oil with a viscosity grade of 22. Viscosity increases with decreases in crude oil API gravity (assuming a constant Watson characterization factor) and decreases in temperature. The effect of solution gas is to reduce viscosity. Above saturation pressure, viscosity increases almost linearly with pressure.
NuFlo™ 547 is designed to reduce viscosities in ultra heavy asphaltene rich crude oil—viscosity reductions of 70% are achievable along with pressure drops of approximately 50% in pipelines. NuFlo™ 547 will also reduce turbulent flow, dissolve and disperse asphaltenes, and paraffins at ambient temperatures.

Emulsion Viscosity Reducers One of the major costs in crude oil production is lifting fluids to the surface for processing. During the lifting process the produced fluid composed of brine and crude oil encounters high shears and pressure drops caused by flowing through electrical submersible pumps or other forms of impingement and restrictions. In this paper, the preparation of the viscosity reducer has been discussed. Several different types of oilsoluble viscosity reducer for the viscous crude oil were prepared by using solution polymerization method and compared by their physical properties and viscosity reduction effect by Infrared (IR), thermogravimetric (TG) and other testing
