2. Drawdown (hydrology) - Wikipedia

   en.wikipedia.org/wiki/Drawdown_(hydrology)

   In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. In surface water hydrology and civil engineering, drawdown refers to the lowering of the surface elevation of a body of water, the water table, the piezometric surface ...

3. Well test - Wikipedia

   en.wikipedia.org/wiki/Well_test

   In hydrology, a well test is conducted to evaluate the amount of water that can be pumped from a particular water well.More specifically, a well test will allow prediction of the maximum rate at which water can be pumped from a well, and the distance that the water level in the well will fall for a given pumping rate and duration of pumping.

4. Well test (oil and gas) - Wikipedia

   en.wikipedia.org/wiki/Well_test_(oil_and_gas)

   Regularly, for example once a month per well, the flow from one and only one selected well is led into the test separator for determining well flow rate for the selected well. [3] The separator divides the flow from the well into the streams of individual products which typically are oil, gas and water, but may include natural-gas condensate ...

5. Drill stem test - Wikipedia

   en.wikipedia.org/wiki/Drill_stem_test

   A drill stem test (DST) is a procedure for isolating and testing the pressure, permeability and productive capacity of a geological formation during the drilling of a well. The test is an important measurement of pressure behaviour at the drill stem and is a valuable way of obtaining information on the formation fluid and establishing whether a ...

6. Slug test - Wikipedia

   en.wikipedia.org/wiki/Slug_test

   The size of the slug required is determined by the aquifer properties, the size of the well and the amount of time which is available for the test. For very permeable aquifers, the pulse will dissipate very quickly. If the well has a large diameter, a large volume of water must be added to increase the level in the well a measurable amount.
