The use of pseudotime: Wellbore storage and the middle time region Conference Paper uri icon


  • © 1986 Society of Petroleum Engineers. The gas flow equation is often linearized to allow liquid type curves to be used to analyze transient tests of gas wells. In the absence of wellbore storage, drawdown tests are best analyzed using the pseudopressure-time linearization. Buildup tests, however, require the pseudopres sure-pseudotime linearization for best results. If wellbore storage is present, both time and pseudotime should be used in a combination analysis for drawdown.
