AQTESOLV introduces a set of diagnostic
plots that help you choose appropriate aquifer models and solutions methods for
your pumping test data. The diagnostic plots display your data on transformed axes
to help identify features such as wellbore storage, fracture flow
and spherical flow.
Radial Flow Plot
Radial Flow plots are useful
diagnostic tools for identifying radial (infinite-acting aquifer) flow behavior and
wellbore storage.
On semi-logarithmic axes, late-time data exhibiting a straight line on a Radial Flow
plot are indicative of radial flow conditions in an infinite-acting aquifer.
On double logarithmic axes, early-time data exhibiting a unit slope on a Radial Flow
plot are indicative of wellbore storage.
Linear Flow Plot
Linear Flow plots are useful
diagnostic tools for identifying fracture flow behavior.
On double logarithmic axes, early-time data exhibiting a unit slope on a Linear Flow
plot are indicative of linear flow conditions to a single fracture with infinite
conductivity or uniform flux along the fracture.
Bilinear Flow Plot
Bilinear Flow plots are useful diagnostic tools for identifying
fracture flow behavior.
On double logarithmic axes, early-time data exhibiting a unit slope on a Bilinear Flow
plot are indicative of bilinear flow conditions to a single fracture with finite
conductivity.
Spherical Flow Plot
Spherical Flow plots are useful diagnostic tools for identifying
spherical flow behavior.
On linear axes, data exhibiting a unit slope on a Spherical Flow plot are indicative of spherical
flow conditions.
