Investigate the Effect of Permeability on the Selection of Diverter in Limestone Matrix Acidizing

This paper will aim at investigating effect of permeability on selecting best diverter in carbonate matrix acidizing. Two types of diverters were used, 15% HCl Gelled Acid and Slickwater+15% HCl. Permeability varied from 50md, 100 and 300md. Results showed that 15% HCl Gelled Acid gave better results than VDA where it had lower skin value and better invasion depth.
