A?pumping test?is a field experiment in which a well is pumped at a controlled rate and water-level response (drawdown) is measured in one or more surrounding observation wells and optionally in the pumped well (control well) itself; response data from pumping tests are used to estimate the hydraulic properties of aquifers, evaluate well performance and identify aquifer boundaries.?Aquifer test?and?aquifer performance test?(APT) are alternate designations for a pumping test. In petroleum engineering, a pumping test is referred to as a?drawdown test.
