AQTESOLV Advantage

No competing aquifer test software can match AQTESOLV's comprehensive set of powerful and easy-to-use tools for data set preparation, diagnostic analysis, solution methods, visual and automatic curve matching, statistical analysis, plots and reports.

"Fantastic tech support!"

Pumping Tests in Nonleaky Confined Aquifers

Combined analysis of drawdown and recovery data using Theis (1935) solution — Combined analysis of drawdown and recovery data from a constant-rate pumping test in a nonleaky confined aquifer using Theis (1935) type-curve solution (data from USBR 1995).

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

Analysis of sinusoidal pumping test — 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 multi-well pumping test in channel aquifer (strip aquifer) using AQTESOLV's automatic image well generation — 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 with derivative from single-well pumping test in nonleaky confined aquifer — 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.

Forward solution with cyclic pumping conditions — Predictive simulation showing drawdown in the pumping well and two observation wells (r=500 and 2000 ft) under cyclic (intermittent) pumping conditions in a nonleaky confined aquifer.
