A spreadsheet program file has been developed to estimate many of the gas properties required by reservoir engineers in their day to day work. This file eliminates the need for published correlations requiring charts or sophisticated fluid property programs that are tedious and time consuming to use. Many existing PC-based spreadsheet program files require more than one operation or spreadsheet to calculate gas parameters. Also, once calculated the results are often difficult to transfer to other programs for calculating other parameters. The gas parameters, calculated by the new spreadsheet program file, include the gas deviation factor Z, compressibility C[sub g], expansion factor E[sub g], and viscosity [mu]g of various pressures and initial reservoir gas gradient. If partial gas analysis (from C[sub 1] to C[sub 5+]) is available, the program also calculates the dry and wet gas heating value. Calculated results are automatically plotted, and tabulated and graphical data can be printed for further use.
