Fig. 3-19. Average relative errors and average absolute relative errors of subsets of the data
described in table 3-14 sorted on measured reservoir oil density at bubblepoint pressure show
the quality of selected correlation equations for estimating reservoir oil densities at bubblepoint
pressure across the full range of this dependent variable.
