Econo - Model A104 -Acid Gelling Agent/Acid Retarder
ECONO-A104 is a highly effective hydrochloric acid gelling agent designed for application in acidizing and fracturing operations. The product effectively gels hydrochloric acid up to 38% and provides stable viscosities at temperatures up to 150o F. In 15% hydrochloric acid, viscosities of 50 to 60 cps are economically produced using ECONO-A104. This gelled acid retards the spending of the acid resulting in increased penetration and treatment effectiveness. Acid systems prepared with ECONO-A104 provide excellent suspension of fines and enhance formation and near well bore clean up during acid flow back. Due to possible reductions in viscosity, the use of anionic products in systems gelled with ECONO-A104 is not recommended. The product is totally compatible with all cationic and nonionic acidizing and stimulation additives, including acid corrosion inhibitors.

It is recommended that the HCl, water, and other additives be thoroughly mixed prior to the addition of ECONO-A104. After proper mixing, ECONO-A104 is typically added to the acid at a load rate of 10 to 50 gallons per 1,000 gallons, depending upon the concentration of the HCl and other additives being used and the desired viscosity. The gel will form immediately upon the addition of ECONO-A104. The system should then be circulated to assure uniform mixing of the ECONO-A104 to provide a consistent viscosity of the treatment fluid. Pilot testing is recommended with the test fluids to determine optimum usage concentrations for specific treatments.
