WELL
DEVELOPMENT
Source: Groundwater and Wells, 2nd edition
“… Eventual specific capacity of a well depends
to a great extent on what development method is
used.”
The graph above shows clearly the impact on
specific capacity when overpumping was
followed by surging, and then surging was
followed by jetting. Specific capacities of the
wells involved in this controlled test were
improved 74% when a 3-step development
approach was employed. The results shown
above are for screen wells rotary drilled with
bentonite fluid additives.
The general conclusion to be drawn is that well
development is best done with a combination of
methods approach, whichever methods are
chosen.
