A "Pressure Transient" refers to a temporary change in pressure within a system, often observed in fluid dynamics. This phenomenon can occur in various environments, such as oil reservoirs, natural gas wells, or water aquifers, when fluid is extracted or injected. The pressure changes can provide valuable information about the properties of the reservoir and the flow characteristics of the fluid. Monitoring pressure transients is crucial for engineers and geoscientists as it helps in understanding reservoir behavior and optimizing extraction techniques. By analyzing these pressure changes, professionals can make informed decisions regarding resource management and enhance the efficiency of production processes.
