A challenge that must be faced in either lithology is diversion. As acid is pumped, it flows preferentially along the most permeable path into the formation. The acid opens these paths up even more, and less permeable, damaged zones are almost guaranteed not to receive adequate treatment. Some technique to divert the treatment fluid toward more damaged formation or damaged perforations is therefore mandatory. There is a variety of diversion techniques and the first attempts at acid treatment placement used chemical diverting additives.
In Sharif Petro Energy, we have used a wide range of chemical diversion in dual core apparatus to enable an even distribution of fluids across the treatment interval. This means you get effective stimulation for maximized production.
