AQTESOLV Radial Flow Plots

AQTESOLV Radial Flow Plots are useful diagnostic tools for identifying infinite-acting radial flow conditions, wellbore storage and closed aquifer behavior.

  • On a semi-log radial flow plot, late-time data exhibiting a straight line are indicative of radial flow conditions in an infinite-acting aquifer.
  • On a log-log radial flow plot, early-time data exhibiting a unit slope are indicative of wellbore storage, an important flow regime to consider in the interpretation of single-well tests (see Figure to right).
  • On a log-log radial flow plot, late-time data exhibiting a unit slope are indicative of a closed aquifer (an aquifer enclosed by no-flow boundaries).
