Abstract

A model to estimate the apparent skin factor for gas reservoirs during acidizing treatments is presented. The model introduces a viscous skin factor to handle the effect of the viscosity difference between the injected fluid and the reservoir fluid on the pressure response. By subtracting the viscous skin factor from the total skin factor obtained from the rate and pressure recorded during treatment, the true damage skin during an acid treatment is obtained. Field examples from Brazil show that the real-time monitoring model for acidizing treatments for gas reservoirs successfully predicts the evolving damage skin factor. The production data for the wells before and after acidizing confirmed the predicted skin factor behavior.
