material balance

1. n. [Well Testing]
An expression for conservation of mass governed by the observation that the amount of mass leaving a control volume is equal to the amount of mass entering the volume minus the amount of mass accumulated in the volume. Through material balance, reservoir pressures measured over time can be used to estimate the volume of hydrocarbons in place.
