Fig. 3-17. Average relative errors and average absolute relative errors of subsets of the data
described in table 3-14 sorted on solution gas-oil ratio at bubblepoint pressure show the quality of
selected correlation equations for estimating reservoir oil densities at bubblepoint pressure across
the full range of this independent variable.
