Analysis of wireline formation test data from gas and non-Darcy flow conditions

Unlike liquid formation tests, in a gas formation test, both compressibilit y and viscosity vary with pressure, and non-Darcy how is more likely. In th is study, the gas formation rate analysis technique is developed to analyze gas pressure tests. We calculated gas pseudopotentials, utilized the geome tric factor concept, and replaced Darcy's equation with Forchheimer's equat ion to study non-Darcy How effects. The technique is applied to a field tes t, and the results are verified by history matching it with a three-dimensi onal near wellbore simulator.
