Interference tests are run by first shutting in the portion of the reservoir in the area affected by the test. Then one produces (or injects into) one well (called the active well) and measures the pressure response in the offset wells. [[:file:pressure-transient-testing_fig9.png|Figure 9]] shows a typical interference test pattern, and [[:file:pressure-transient-testing_fig10.png|Figure 10]] is a plot of a typical response in an observation well.
