Superposition in time

Superposition in time

A mathematical computation that accounts for the flow-rate history in analytical models generated to match with pressure-transient test data. The pressure-derivative response can be distorted in late-time data by the effects of superposition in time, except in data acquired from an initial drawdown. Analysts must be aware of this limitation in diagnosing reservoir features from the pressure-derivative response.
