Visco Elastic Surfactant VES （160℃）

Visco Elastic Surfactant VES （160℃）

The viscosity of the system rapidly increases with the increase of the PH value. The viscosity reaches its peak when pH exceeds 4. The colloid of peak viscosity maintains good viscosity with the temperature at or below 160°C/320°F. It is environmentally friendly without leaving residues.

Description
General

 

The viscosity of the system rapidly increases with the increase of the PH value. The viscosity reaches its peak when pH exceeds 4. The colloid of peak viscosity maintains good viscosity with the temperature at or below 160°C/320°F. It is environmentally friendly without leaving residues. It is used in heterogeneous reservoir matrix acidizing, the acid fluid system can become more viscous automatically along with the reaction with the rock, with the function of facilitating diversion acidizing, without secondary damage to geosphere. The ZX-DA-01 Visco Elastic Surfactant (VES) are compatible with the acid corrosion inhibitor of series ZX-DA-02.

Advantages and Features

  1. The ZX-DA-01 Visco Elastic Surfactant (VES) Compatible with ZX-AD-02 series acid corrosion inhibitors, withstanding high temperatures. The diversion acid system shows excellent corrosion inhibition at 160°C/320°F while maintaining good viscosity.
  2. Effective in enhancing production in carbonate layers.
  3. Suitable for various carbonate rock formations.
  4. Composed of surfactants, serving as a clean diversion agent without harming the formation.
  5. Low initial acid viscosity for easy pumping.
  6. Gel breaks upon contact with oil or gas, eliminating the need for additional breakers.
  7. Features low surface and interfacial tension for automatic flowback without additional flowback aids.
  8. The ZX-DA-01 Visco Elastic Surfactant (VES) ban be customized to meet specific requirements, including initial acid viscosity and gelling point adjustments.
