This paper presents a new gas well testing analysis method considering gas well producing at constantpressure in infinite gas reservoir accounting for high velocity non-Darcy flow ef.
The equation of pressure behavior has been established for composite infinite gas reservoir of anomalous pressure in the condition of constant pressure, and we apply it to obtain the equation of rate.
