Analysis of data from recovery test with Agarwal method using Theis (1935) type-curve solution (data from USBR 1995).

Displacement measured during a sinusoidal variable-rate pumping test in which the rate varied through several cycles of extraction and injection (Rasmussen et al. 2003).

Analysis of drawdown measured in pumped well and three observation wells during a constant-rate pumping test in a nonleaky confined buried channel (strip) aquifer near Estevan, Saskatchewan, Canada (Walton 1970).

Analysis of drawdown and recovery data with derivative from a constant-rate single-well pumping test in a nonleaky confined bedrock aquifer (Papadopulos and Cooper 1967). Early-time data show wellbore storage effect before derivative becomes constant (infinite-acting conditions). The low storage coefficient suggests well loss.
