pressure depletion

1. n. [Well Testing]
The drop in average reservoir pressure from fluid production. All bounded reservoirs have pressure depletion (a drop in average reservoir pressure) associated with fluid production. Water influx counters this effect in reservoirs that are surrounded or underlain by aquifers. Likewise, the presence of a gas cap can slow pressure depletion.
