ABSTRACT OF THE DISCLOSURE A method of determining the volume of gas in a well below the wellhead includes measuring the gas flow rate in the well annulus, closing the wellhead and measuring the change in pres- sure with time, and calculating the volume from the recorded data. A further method includes determining the change of pressure with time with the wellhead closed, venting the well through a calibrated orifice and measuring pressure changes with time for a short interval of time, and calculating from the recorded data the flow rate through the orifice, the annu- lar gas volume and the annular gas rate. Pump rates and fluid rates can also be determined. A reverse technique using in- jection is also disclosed.
