Surfactant NRG-VES HT

NRG-VES HT is a viscoelastic surfactant for high temperature matrix acidizing (350°F) based on different zwitterionic compounds and special additives in alcohol solvent. NRG-Vashti highly effective product designed to produce different smart self-diverting acid compositions for high-temperature conditions.

Surfactant NRG-VES HT

Appearance: liquid from colorless to dark brown, opalescence is allowed.

Density at 20°C: 0.80-1.00 g/cm³.

Solubility in water: soluble.

Flammability: flammable liquid and vapour.

Specific Gravity:
Effectively increases the viscosity of the acid when interacting with carbonate rock.

Increased zonal coverage at high tempearatures.

Retards the rate of reaction for deeper penetration of live acid into the formation.
