PREDICTING LIQUID GRADIENT IN A PUMPING WELL ANNULUS. Conference Paper

abstract

• Prediction of gas-entrained liquid column density is the key to an accurate estimation of bottomhole pressure in a pumping well annulus during a pressure buildup test. Estimation of the changing liquid column density is generally made using one of the three correlations available in the petroleum literature. These correlations relate the desired gas void fraction with the superficial gas velocity. This work proposes two correlations for estimating gas void fraction in the bubble and slug flow regimes.
