Step-Drawdown Test Analysis

AQTESOLV provides more features for the interpretation of step-drawdown tests than competing software.

Competing products limit step-drawdown test analysis to fully penetrating line-source wells in nonleaky confined aquifers. Only AQTESOLV provides methods for nonleaky and leaky confined aquifers with options for partial penetration and wellbore storage.

Tests in Leaky Confined Aquifers

Only AQTESOLV gives you a choice of models beyond nonleaky confined conditions for greater flexibility in your analysis of step-drawdown tests.

Methods for step-drawdown tests in the literature typically assume nonleaky confined conditions; however, as shown by Bear (1979), most constant-rate pumping test solutions may be adapted for the analysis of linear and nonlinear well loss associated with step-drawdown tests.

For example, AQTESOLV modifies the solution by Hantush and Jacob (1955) to analyze step-drawdown tests in leaky confined aquifers.
