Data for: Viscosity and contact angle prediction of low water-containing heavy crude oil diluted with light oil

Table 3 is the basic compositions and physical properties of the heavy crude oil and light oil samples. Table 4 is the measured viscosity of crude oils at different temperature points. Table 5 shows various correlations for crude oil viscosity at different temperatures. Table 6 gives average relative error, average absolute error, maximum relative error, and standard deviation for all correlations in different dilution ratios. Table 8 describes the comparison between the predicted and actual viscosities of heavy oil related to water contents. Table 9 is the contact angles between all mixture oils and both acrylic tube and X80 pipeline steel surfaces in the air atmosphere and in water bath. Table 10 is the surface roughness of two materials. Table 11 describes the comparison between the predicted and actual contact angle of previous model and the model in this paper.
