An hydrocarbon reservoir consists of seven horizontal layers. The areal extension of this reservoir is estimated at $2000$ acres. The gross thickness, net thickness, porosity, gas saturation, and water saturation of each of layer are given in the following table. The oil formation volume factor, gas formation volume factor, and solution gas$/$oil ratio at initial reservoir conditions are $1\mathrm{.}58R\frac{B}{S}TB,0\mathrm{.}0008R\frac{B}{s}cf,$ and $1040sc\frac{f}{S}TB,$ respectively.
