ACID EMULSIFIER RETARDER

EM-AS-55R makes a very stable emulsion with 70% acid and 30% diesel or kerosene fuel under the proper conditions. For a good result, it is important to dissolve EM-AS-55R first in diesel or kerosene fuel then the acid mixed sufficiently. Varying degrees of emulsion viscosity can be formed. Emulsions can be designed to provide for deeper penetration of live acid into the formation where elevated bottom-hole temperature tends to increase acid reaction rates.

The amount of EM-AS-55R Acid Emulsifier required will depend on the stability desired and the presence and nature of other acid additives to be employed. EM-AS-55R requirement will usually be in the order of 1%-3% (10-30 gpt) of the total emulsified fluid.
