Compressibility factor, z, values of natural gases are necessary in most petroleum gas engineering calculations. Most common sources of the compressibility factor values are experimental measurements, equations of state method and empirical correlations. If laboratory measured data were unavailable, empirical correlations can be used to determine the compressibility factors. However, there might be discrepancies between laboratory-measured values with those obtained by correlations which, in turn, might affect the outcome of a study. Sensitivity analysis is a technique used to determine how different values of the compressibility factor would affect well testing and material balance equation calculations. Under a given set of data, this technique is used within specific boundaries that will depend on one or more methods, such as the effect that changes in reservoir's parameters obtained from build-up test and calculations of gas initial in place by using material balance equation. This study highlights how changes in the compressibility factor affect well testing results and volume of gas initially in reservoir calculated using material balance equation. Three wells producing under partial water drive mechanism were considered for this study. Dranchuk and Abu-Kassem's method was found to have the lowest error. [ABSTRACT FROM AUTHOR] |
