Pumping rate Quality factor

Successful fradure acidizing treatments do not depend solely on good fluid-loss properties (30). Adequate fracture flow capadty must be established by the add system used. The quantity of rock removed and the pattern in which it is removed from the fracture face are important. Fracture flow capadty is dependent on the nature of the rock and the characteristics of the add, such as add type, volume, and concentration. Other factors that lead to increased fracture flow conductivity include foam quality and pumping rate. As long as the foam is stable, foamed add of any quality increases the fracture flow conductivity when compared with non-foamed adds. As well, increases in total treatment pumping rates achieve better fracture conductivities because of greater acidized fradure lengths.
