Thermodynamic pump testing is a form of pump testing where only the temperature rise, power consumed, and differential pressure need to be measured to find the efficiency of a pump. These measurements are typically made with insertion temperature probes and pressure probes fitted to tapping points on the pump's inlet and outlet. [ 1 ]
Often the well efficiency is determined from this sort of test, this is a percentage indicating the fraction of total observed drawdown in a pumping well which is due to aquifer losses (as opposed to being due to flow through the well screen and inside the borehole). A perfectly efficient well, with perfect well screen and where the water flows ...
A typical multiplier for a new unit within a refinery would be in the range of 5.0. When the purchase price of all the pumps, heat exchangers, pressure vessels, and other process equipment are multiplied by 5.0, a rough estimate of the total installed cost of the plant, including equipment, materials, construction, and engineering will be achieved.
A slug test is a variation on the typical aquifer test where an instantaneous change (increase or decrease) is made, and the effects are observed in the same well. This is often used in geotechnical engineering settings to get a quick estimate (minutes instead of days) of the aquifer properties immediately around the well.
Pump curves are quite useful in the pump selection, testing, operation and maintenance. Pump performance curve is a graph of differential head against the operating flow rate. They specify performance and efficiency characteristics. Performance tests are done on the pumps to verify the claims made by the pump maker.

the well does not or cannot have a pump installed on it (slug tests do not require pumping), the transmissivity of the material the well is cased in is too low to realistically perform a proper pumping test (common for aquitards or some bedrock monitoring wells), or
