ABSTRACT:
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 pressure 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 annuluar gas volume and the annular gas rate. Pump rates and fluid rates can also be determined. A reverse technique using injection is also disclosed.
