AquiferTest Analytical Methods

An extensive suite of analytical methods

AquiferTest delivers an extensive set of solutions suitable for all types of aquifers and test conditions. Analyze confined, unconfined, leaky, and fractured aquifers. Account for various well conditions including wellbore storage, horizontal wells, and single-well analyses.

Time Drawdown-Discharge Plot
Pumping TestsTheis (1935) – confined, isotropic aquifer
Theis with Jacob Correction (1944) – unconfined, isotropic aquifer
Boulton (1963) – unconfined, anisotropic aquifer
Neuman (1975) – unconfined, anisotropic aquifer, partially-penetrating well
Hantush-Jacob (Walton, 1962) – leaky aquifer
Hantush (1960) -leaky aquifer, with storage in aquitard
Warren Root (1963) – dual porosity, fractured flow
Moench (1984, 1988) – fractured flow, with skin
Papadopulos & Cooper (1967) – well bore storage/large diameter wells/single well
Agarwal Recovery (1980) – recovery analysis
Clonts and Ramey (1986) – horizontal wells
Neuman and Witherspoon (1969) – confined, two-aquifer system
