Q$3/$ A$)$ Calculate the gas density of $0\mathrm{.}7$ specific gravity gas containing $10\%$

$C{O}_2$ and $10\%H_{2}S(mol\%)$ at pressure of $2500a$ and a temperature of

$200F$ using $($Robinson et al method$).$

Q$3/$ B$)$ The following example was used by standing to illustrate the

method generating a future IPR. Present time test data : day,

$\{$:$P_{wf}=1870g).$ Generate IPR for both present and future times.
