| Only AQTESOLV
provides a set of powerful diagnostic
plots that help you choose appropriate aquifer models and solutions methods for
your pumping test data. The diagnostic plots display
field data on transformed axes and enable you to identify features such as infinite-acting radial flow, wellbore storage,
fracture flow, channel flow
and spherical flow. |

Wellbore storage detected in pumped well data.
|
| |
| Radial flow plots are useful
diagnostic tools for identifying infinite-acting radial flow conditions,
wellbore storage and closed aquifer behavior. |
| |
 | On semi-logarithmic axes, late-time data on a radial flow plot
exhibiting a straight line are indicative of radial flow conditions in an infinite-acting aquifer. |
|
| On double logarithmic axes, early-time data on a radial flow plot
exhibiting a unit slope are indicative of wellbore storage. |
|

|
|
 |
|
Linear flow detected in a stratified aquifer with steeply dipping beds.
|
| |
| Linear flow plots are useful diagnostic tools for
identifying linear flow behavior in single fractures and channel aquifers. |
| |
| On double logarithmic axes, early-time data on a linear flow plot
exhibiting a unit slope are indicative of linear flow conditions to a
single fracture with infinite conductivity or uniform flux along the
fracture. |
|
| On double logarithmic axes, late-time data on a linear flow plot
exhibiting a unit slope are indicative of linear flow in a channel
aquifer. |
|

|
|
|
Bilinear flow plots are useful
diagnostic tools for identifying fracture flow behavior and flow in
dikes.
|
| |
| On double logarithmic axes, early-time data on a bilinear flow plot
exhibiting a unit slope are indicative of bilinear flow conditions to a
single fracture with finite conductivity. |
|
| On double logarithmic axes, late-time data on a bilinear flow plot
exhibiting a unit slope are indicative of bilinear flow in a
permeable dike
surrounded by less permeable country rock. |
|
|
| |
|
|
|
Spherical flow plots are useful diagnostic tools for
identifying spherical flow conditions such as may occur in the vicinity of a
partially penetrating well.
|
| |
| On linear axes, data on a spherical flow plot exhibiting a negative
unit slope are indicative of spherical flow conditions. |
