Definition - What does Transient-Pressure Testing mean?
Transient-Pressure Testing is the measurement of pressure recorded as function of time, generally in a borehole near productive interval when the well flow rate is changed. This test is considered as a primary source of dynamic reservoir data which forms the basis of transient well testing analysis. It is used primarily for detecting the properties of reservoir rocks and limits of a producing formation. The objective of the test at any stage ranges from simple measurement of the reservoir pressure to the complex description of the reservoir features.
Petropedia explains Transient-Pressure Testing
Transient-Pressure Testing is said to be a routine procedure used in the petroleum industry to ascertain the ability of a well to inject or produce. It also helps in the detection of the reservoir features of wells near a wellbore. The process also involves subjecting of wells to an array of rate of changes while measuring the response of pressure transient. Transient-Pressure Testing is usually designed for incorporating factors like measuring device resolution, type of reservoir, hydrocarbon fluid and the overall objective of the test. It is important to forward the pressure test simulation using a series of parameters to forecast the possible responses which would satisfy the test objectives.
