The transient drainage radius concept, developed for wells producing at constant flow rate, has proven to be consistent for wells producing at constant pressure. Also applicability of the constant pressure solution developed by Ehlig-Economides and Ramey (1981) for oil flow has been proven for gas flow. Effects of non-Darcy flow, and other reservoir and gas properties on test results have been investigated. With this analysis, reservoir permeability, skin factor, and existence of non-Darcy flow can be estimated.
