Stock-Tank Oil Gravity, °API
Fig. 3-45. Average relative errors and average absolute relative errors of subsets of the
data described in table 3-28 sorted on stock-tank oil gravity show the quality of selected
correlation equations for estimating reservoir gas specific gravities across the full range of this
independent variable.
