Problem statement $1$

An undersaturated oil reservoir is producing from the oil zone solely. The daily oil production is $5,000stb.$ However, due to the pressure drawdown at the bottom hole coning effects are taking place and $1$ stb of water is produced for each $10stb$ of total liquid $($oil$+$water$).$ The oil is produced at surface directly to a tank. The GOR at the tank is equal to $52sc\frac{f}{s}tb.$ The oil and water volume factors at reservoir conditions are $B_0=1\mathrm{.}3r\frac{b}{s}tb$ and $B_w=1\mathrm{.}02r\frac{b}{?}$ stb respectively. Compute:

The underground withdrawal

The daily gas rate at SC

The reservoir oil $R_s$ at reservoir conditions
