Viscosifiers are chemical additives used to modify and control fluid viscosity in various oilfield operations. These compounds create molecular structures that enhance fluid thickness and stability under different conditions. UNPChemicals' VESMET series utilizes tallow aminoamine oxide and zwitterionic surfactant technologies to deliver effective viscosity control. The tallow aminoamine oxide components provide reliable viscosity building properties, while the zwitterionic surfactants offer adaptable performance across diverse fluid environments. Together, these components create versatile viscosifier solutions suitable for multiple oilfield applications requiring precise rheological management.

The VESMET series represents UNPChemicals' advanced viscosifier technology, featuring two highly specialized surfactant formulations engineered for optimal performance in demanding oilfield applications.
The tallow aminoamine oxide component is a high-performance cationic surfactant that delivers superior viscosity-building capabilities through its unique molecular structure. The amine oxide functional group provides excellent thermal stability, maintaining viscosity integrity even under elevated downhole temperatures. This formulation demonstrates particular effectiveness in foam-based fracturing fluids, where it enhances foam stability while improving proppant transport efficiency. Its robust performance makes it ideal for high-temperature reservoirs and extended operations requiring long-term viscosity retention.
Complementing this technology, the zwitterionic surfactant formulation offers unmatched versatility in challenging fluid environments. Its dual-charge molecular structure provides exceptional salt tolerance, enabling consistent viscosity performance across a wide range of water qualities - from fresh water to high-salinity brines. The zwitterionic chemistry allows for reversible viscosity characteristics, giving operators precise control over fluid rheology during different operational phases. This intelligent viscosity modulation ensures optimal fluid performance during injection while facilitating efficient post-operation cleanup.
What is a Viscosifier?
A viscosifier is a chemical additive designed to increase and control the viscosity (thickness) of fluids used in oilfield operations, creating stable, gel-like structures that improve fluid performance; these additives work by forming molecular networks that enhance carrying capacity, suspension properties, and stability under various temperature and shear conditions.
What are the main types of Viscosifiers?
The primary types include polymer-based viscosifiers (like guar gum or cellulose derivatives), surfactant-based systems (such as UNPChemicals' VESMET series with tallow aminoamine oxide and zwitterionic surfactants), and clay-based additives (like bentonite), each offering distinct rheological properties for different applications from drilling to fracturing.
Where are Viscosifiers commonly applied?
Viscosifiers are widely used in hydraulic fracturing fluids to suspend proppants, in drilling muds to improve cuttings removal, in completion fluids to control filtration, and in enhanced oil recovery (EOR) operations to improve sweep efficiency, with specific formulations tailored to each application's temperature, salinity, and shear requirements.
How do you select the right Viscosifier?
Selection depends on fluid type, downhole conditions (temperature, pressure, salinity), environmental regulations, and performance needs; key considerations include thermal stability (e.g., zwitterionic surfactants for high-salinity HT/HP wells), clean break characteristics, compatibility with other additives, and whether reversible viscosity control is required for post-operation flowback.
Why choose surfactant-based Viscosifiers like VESMET?
Surfactant-based viscosifiers like VESMET offer superior salt tolerance, temperature resistance, and controllable rheology compared to traditional polymers, while providing excellent proppant transport and clean break properties - particularly valuable in complex reservoirs where conventional viscosifiers underperform or leave damaging residues.
