This article is devoted to the method of calculating the annular gas flow rate, taking into account the dependence of the flow rate on the pressure in the annulus. The article describes the assumptions made in the methodology, as well as their impact on the overall calculation error. A confirmation of the reliability of the method was obtained using direct measurement of the flow rate by a gas meter.
