Pressure Transient Analysis
Definition - What does Pressure Transient Analysis mean?
Pressure Transient Analysis is sometimes also called as Pressure Transient Well Test. This analysis is a methodology of testing the flow rate and pressure of hydrocarbon liquids inside the wellbore. Thus, this test helps in determining the key performance indicators of a well and helps in mitigating any flaws that will hinder the production rate from an oil or gas well once it is live.
Petropedia explains Pressure Transient Analysis
Pressure Transient Analysis provides a detailed test procedure for measuring the performance parameters of an oil or gas well once it goes live. To conduct this test, the reservoir data is acquired such as reservoir pressure, flow rate from the reservoir, its geology and once data is collected, it is interpreted. Pressure transient analysis is performed during various development stages of an oil or gas well such as before drilling, in between the drilling process, once oil well has been completed as well as when it has gone live and started producing.
This analysis provides following information:
- Helps in analysing the rock permeability and its structure.
- Skin factor estimation
- Provides information on reservoir properties.
- Provides information on cracks and flaws in between that may act as flow barriers.
