Fig. 3-12. Average relative errors and average absolute reltative errors of subsets of data
described in table 3-11 sorted on solution gas-oil ratio at bubblepoint pressure show the quality
of selected correlation equations for estimating oil compressibilities for pressures greater than
bubblepoint pressure across the full range of this independent variable.
