Derivative Analysis

Combine observation and derivative data on a single plot for more effective curve matching!

Derivative plots are useful diagnostic tools for examining the effects of wellbore storage, recharge and barrier boundaries, leakage, delayed gravity response and fracture flow.

In addition to providing this diagnostic method of analysis, AQTESOLV also lets you perform interactive visual curve matching with derivative plots to estimate aquifer properties.
