The Defining of Gas Well Testing Fundamentals
In the petroleum industry, a well test is the execution of a set of planned data acquisition activities. The acquired data is analyzed to broaden the knowledge and increase the understanding of the hydrocarbon properties therein and characteristics of the underground reservoir where the hydrocarbons are trapped. The ability to analyze the performance and forecast the productivity of gas wells and to understand the behaviour of gas reservoirs with a reasonable degree of accuracy is of utmost importance in today’s natural gas industry. One of the most useful aids in analyzing gas well performance is the flowing well test. A complete analysis and understanding of the results of an appropriate well test enables one to determine the stabilized shut-in reservoir pressure, determine the rate at which a well will flow against a particular pipeline “back pressure,” predict the manner in which the flow rate will decrease with depletion and the resulting decline in reservoir pressure, and estim
