... of mass balance of gas phase in the annulus may be used to estimate annular gas rate and flowing bottomhole pressure of a pumping oil- well. The method enables one to calculate the ann- ular gas volume, including gas bubbles in the oil column. The knowledge of annular gas volume can then be used to find...

Paper Number: PETSOC-78-29-19
... bottom hole pressure the volume of gas in the annulus is related to the flo~ rate through Lhe critical flow prover as follows: v =[ qz TzIZ86 (m1 - mzl} - pC - 3) in which C is the product of the liquid gradient and the annular capacity. The annular gas rate can be shown to be as fol- lows, for either...
