c$)$ A small gas reservoit has an initial reservoir pressure of $3400a,$ and a reservoir temperature of ${217}^{0}F.$ The pressure$-$production profile was given as

$\backslash$table$[[$Pressure $($Psia$),$Gp $($MMscf$),$Bg $($cuf$/$scf$)],[3400,0,0\mathrm{.}0053198],[2866,100,0\mathrm{.}005948],[1764,390,0\mathrm{.}00912],[1394,490,0\mathrm{.}011266]]$

Determine:

i$.$ The initial gas in place

ii$.$ The cumulative gas produced to abandonment pressure of $500$Psia which has a deviation factor of $0\mathrm{.}87.$ Assuming Gas price is $$=\frac{15}{s}cf$ of gas and the gas recovery factor $=0\mathrm{.}75,$ what is the expected revenue from the sale of gas produced to abandonment.
