Well testing is a process used to evaluate the performance and capacity of a water well or oil well. This involves measuring the flow rate, pressure, and other characteristics to determine how much fluid the well can produce over time. It helps assess the well's efficiency and sustainability. During well testing, various methods such as pump tests and drawdown tests are employed. These tests provide valuable data for engineers and geologists to make informed decisions about resource management and to ensure that the well meets the needs of its users without causing depletion or environmental harm.
