Pressure Transient Well Test
Definition - What does Pressure Transient Well Test mean?
Well Test is sometimes also called as Pressure Transient Analysis. The primary purpose of performing a pressure transient well test is to determine the key performance indicators of an oil or gas well i,e., the pressure from the well reservoir so that the hydrocarbons can rise to the top of the surface of the well by itself or with the help of minimal external pressure and whether adequate flow rate will be there or not.
Petropedia explains Pressure Transient Well Test
Pressure Transient Well Test lets the engineers know the detailed procedure of well performance testing by understanding various parameters such as rock geology, reservoir position, amount of hydrocarbons present in a reservoir, amount of pressure hydrocarbons are stored in a reservoir, etc. All this data is collected and examined to understand the well pressure as well as flow rate when an oil or gas well will go live i.e. once it will start producing. This analysis becomes necessary so that if any flaws appear during the construction stage of the well, a proper action steps can be implemented. This test is conducted over a layered reservoirs where multi phase flow conditions are there.
