New Acid-Diversion Technique Helps Increase Oil Production and Simultaneously Reduce Water Cut

One of the critical measures of success in matrix acidizing is to get the acid distributed across all the zones of interest, thus<br>ensuring they are all stimulated and maximum production is achieved. Because most producing zones are not homogeneous<br>in terms of permeability, porosity, water saturation, or the degree of damage they have experienced, uniform distribution of<br>acid during the acid job is seldom achieved.
