Dimensionless drawdown correlating parameter by Carter
Input(s)
\(\mu_{g i}\): Initial Gas Viscosity \((\mathrm{cP})\)
\(\mu_{\text {gavg }}\): Average Gas of Viscosity \((\mathrm{cP})\)
\(c_{g i}\): Initial Gas Compressibility \((1 / \mathrm{psi})\)
\(c_{\text {gavg }}\): Average Gas Compressibility \((1 / \mathrm{psi})\)
Output(s)
\(\lambda\): Dimensionless Drawdown Correlating Parameter (dimensionless).
Formula(s)
\[
\lambda=\frac{\mu_{g i} * c_{g i}}{\mu_{\text {gavg }} * c_{\text {gavg }}}
\]
