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

7 PAGES (1730 WORDS) Petroleum Engineering Paper
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.
