Acid Retarder

Precision Acidizing to Enhance Reservoir Contact

Stimulation Acid Retarder
Delayed Acidizing System for High-Temperature Stimulation

High-temperature stimulation faces the challenge of rapid acid reaction, limiting acid penetration and treatment effectiveness. At DOSAS, we go beyond traditional stimulation. Our next-generation delayed acidizing systems are engineered to deliver smarter, safer, and deeper results. By integrating cutting-edge acid retarders, acid emulsifiers, gelling agents, and viscoelastic surfactants, we ensure that the reaction activates exactly where it matters.

performance results show the Less corrosion, longer contact time, and deeper acid penetration. Our technology enhances wormhole creation, boosts permeability even in challenging low-permeability formations, and brings new life to ageing wells.


Acid Retarder Chemicals

Acid retarders control reaction time, extending exposure for deeper penetration, enhancing performance and simplifying  

  • Without post-treatment cleanup or breakers, delivers outstanding permeability
  • Performs reliably from 120°F (49°C) up to 300°F  (149°C) across diverse reservoirs.
  • Compatible with acidizing package. 

Engineering Acid Retarders for Maximum Stimulation Performance 

The DOSAS Technical teams develop tailored acid systems that maximize treatment efficiency, reduce formation damage, and improve operational outcomes in challenging carbonate formations. Our laboratory team rigorously evaluates acid retarders under simulated reservoir conditions to precisely control acid-rock reactions by leveraging core flood testing, advanced CT imaging, and high-temperature rheology.
