Definition - What does Transient Pressure mean?
Transient Pressure is the pressure that surges rapid accelerations into a water distribution system. It is essential to calculate Transient Pressure as it helps to avoid device failures, pipe raptures, backflow of water and system fatigue. The analysis is done over a short interval of time as it fluctuates with small variations in the volume of the fluid. The pressure can be monitored when the well is closed and the fluid is at equilibrium state. It eventually occurs when there is sudden change in the pumping and pipeline systems.
Petropedia explains Transient Pressure
The major occurrence of Transient Pressure causes water hammer which has many adverse effects as it is high enough to cause the destruction of the pipelines. Various tests have been conducted to get an estimate about the pressure beforehand. The Transient Pressure includes:
- Accurate measurement of reservoir pressure
- Determining the hydraulic communication between the wells
- Characterization of formation damage
The analysis is performed after a certain period of time that includes diverse stages of completion, production and drilling. The value of Transient Pressure is importance as the flow rate of fluids changes rapidly due to valve closures or pump stoppages.
