Abstract

Every gas well will suffer from liquid loading problem as the rate from the well declines. Every gas well produces some produced water (if not also condensate) and that water cannot be carried to the surface at lower gas flow rates. Liquid loading results in premature abandonment of a gas well as the liquid accumulates at the bottom of the well. With the proliferation of horizontal wells producing from gas reservoirs, it is not only important to predict the liquid loading in these wells but also the vertical location where the liquid loading is initiated. The proposed methodology predicts the liquid loading in inclined wells and also the location where it is initiated. The method is superior to commonly used technique of Turner et al. equation which is valid for vertical wells. We have validated the method by applying it to the literature data as well as to large number of horizontal wells.
