UZP-AT10 Acid Gelling Agent
UZP-AT10 is modified polyacrylamide, used in gelling acid, is applied to delay the reaction speed of acid-rock reaction and reduce the leak-off rate. This product can be quickly dissolved in the acidizing fluid and increase the acid viscosity. It has characteristics of high-temperature resistance, good compatibility, outstanding low friction performance.

Dosage and usage
Firstly prepare acid solution with a concentration of 0.3%-1.0% according to the characteristics of the formation and the construction requirements before apply UZP-AT10. Due to the large amount of dosage, we use Venturi Principle to configure gelling acid system. Inhaled the UZP-AT10 powder into the ejector, mixed with acid in the throat of the ejector, and then circulated with acid pump for two to three cycles, followed by the next day’s construction. Adding appropriate additives into this circulating system. The product is cationic, compatibility experiments should be done in advance.
It also can be used as drag reducer in the acid system, the dosage is 0.1-0.15%, flow velocity ≥ 8m/s, the drag reduction rate can reach more than 70%.
