Pumping Test Analysis Methods - Flexible Assumptions

Before doing the pumping test analysis, it is helpful to plot the time-drawdown data, or the time vs. drawdown with variable discharge rates. These plots are explained in the following sections:

•Drawdown vs. Time

•Drawdown vs. Time with Discharge

•Confined - Theis

•Leaky - Hantush-Jacob (Walton)

•Hantush - Storage in Aquitard

•Wellbore Storage and Skin Effects (Agarwal 1970)

•Unconfined, Isotropic - Theis with Jacob Correction

•Unconfined, Anisotropic

•Fracture Flow, Double Porosity

•Single Well Analysis with Well Effects

•Large Diameter Wells with WellBore Storage - Papadopulos-Cooper

•Recovery Analysis - Agarwal Solution (1980)

•Horizontal Wells (Clonts & Ramey)*

•Neuman & Witherspoon

•Multi-Layer-Aquifer-Analysis*
