The reaction of hydrochloric calcium carbonate is very vigorous and is even faster at very high temperature. This will result in the stimulation of the highest permeable area, without stimulating other sections of the productive zone. To get uniform stimulation of the entire zone, diversion using gelled acid is very effective.
SL-ACD2520L is an effective cationic polymer emulsion for gelled acid systems. It can rapidly thicken the acid with high viscosity in a very short time. SL-ACD2520L increases the viscosity of the acid solution, slows down the acid reaction rate.
