Dry Acid Mixture – SKS
It is used in well chemical processing technology to increase productivity of production wells and injectivity of injection wells
FEATURES OF REACTIONS:
Introduction of a modifier increases the dissolution capability of the composition and prevents secondary sedimentation. While dissolved in oil-saturated reservoir it does not provide the growth in oil viscosity and formation of stable water-oil emulsions, thus positively influencing the processes of well start-up and its further operation

* The recipe of each acid composition is tested in lab conditions according to the conditions of each individual well.
CHEMICAL COMPOSITION
- A mixture of crystalline acids, complexons and surfactants
ADVANTAGES OF USAGE
- Slowed down rate of reaction with the rock
- Resistance to ferric hydroxide formation
- Low corrosion activity
- Easy storage conditions and transportation to areas of difficult access
- Compatibility with formation fluids of different nature
APPLICATION TECHNOLOGY
- Preparation of working solution
- Injection of the acid composition into the well
- Squeezing with water
- Exposure for reacting for 6-8 hours
