The reservoir gas in a wet gas reservoir has a specific gravity of $1\mathrm{.}295,$ a hydrogen sulfide

concentration of $20\mathrm{.}9$ mole percent, and a carbon dioxide concentration of $44\mathrm{.}7$ mole

percent. Determine a value of z$-$factor for use at reservoir conditions of $5720$ psig and $268\backslash$deg F$.$ Answer: z$=0\mathrm{.}8$
