Example:
The data given:
\[
\begin{array}{l}
P i=3500 \text { psi } \\
p=3000 \mathrm{psi} \\
Q 0=32,000 \mathrm{sTB} / \mathrm{day} \\
B 0=1.4 \mathrm{bb} / \mathrm{STB} \\
G O R=900 \mathrm{sc} / \mathrm{sTB} \\
\mathrm{RS}_{\mathrm{s}}=700 \mathrm{sc} / \mathrm{sTB} \\
B G=0.00082 \mathrm{bbl} / \mathrm{scl} \\
Q W=0 \mathrm{BW}=1.0 \mathrm{bbl} / \mathrm{STB}
\end{array}

Answer

\(J=15270.7568\)

Steps

Step 1 ：\(J=R_{s} B_{G} / B_{0}\)

Step 2 ：\(J=(700\mathrm{sc} / \mathrm{sTB}) (0.00082 \mathrm{bbl} / \mathrm{scl}) / (1.4\mathrm{bb} / \mathrm{STB})\)

Step 3 ：\(J=15270.7568\)
