Fig. 3-27. Average relative errors and average absolute relative errors of subsets of the data
described in table 3-9 sorted on reservoir pressure show the quality of selected correlation
equations for estimating oil formation volume factors for pressures equal to and less than
bubblepoint pressure across the full range of this independent variable.
