Fig. 3-7. Average relative errors and average absolute relative errors of subsets of the data
described in table 3-9 sorted on measured solution gas-oil ratio show the quality of selected
correlation equations for estimating solution gas-oil ratios at pressures less than bubblepoint
pressure across the full range of this dependent variable.
