Dimensionless pressure drop during pseudo-steady state flow for a horizontal well in a bounded reservoir
Input(s)
\(t_{D A}\): Dimensionless Time (dimensionless)
\(C_{A h}\): Shape Factors for Horizontal Wells (dimensionless)
L: Length of Horizontal Well (ft)
A: Drainage Area (ft)
Output(s)
\(P_{D}\): Wellbore Dimensionless Pressure Drop (dimensionless)
Formula(s)
\[
P_{D}=2 * \pi * t_{D A}+0.5 * \ln \left(\frac{A}{4 *\left(\left(\frac{L}{2}\right)^{2}\right)}\right)+0.5 * \ln \left(\frac{2.2458}{C_{A h}}\right)+0.5 * 2.77
\]
