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. Analyse confined, unconfined, leaky, and fractured aquifers. Account for various well conditions including wellbore storage, horizontal wells, and single-well analyses.
| Drawdown Plots | Time Drawdown Plot Time Drawdown-Discharge Plot |
| Pumping Tests | Theis (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 Hemker and Mass (1987) – multi-aquifer system Theis Recovery (1935) confined Cooper Jacob: • Type I: Time-drawdown • Type II: Distance-drawdown • Type III: Time-distance-drawdown |
| Well Performance | Specific Capacity Hantush-Bierschenk (Hantush, 1964; Bierschenk, 1963): • Well loss • Well efficiency |
