Fig. 3-10. Average relative errors and average absolute relative errors of subsets of the data
described in table 3-11 sorted on stock-tank oil gravity 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.
