DosVesta™ 201 Diverting Agent
Enhanced Zonal Contact Through Polymer-Free Acid Diversion
DosVesta™ 201 Diverting Agent
Self-Diverting Fluid System for Acid Stimulation
DosVesta™ 201 product is optimized for high-temperature wells to enhance stimulation efficiency, improve reservoir contact, and minimize formation damage for more consistent well performance. This polymer-free, self-diverting surfactant system enhances acid placement in carbonate formations for cleaner and more effective treatments. Powered by reactive viscoelastic technology, the fluid instantly increases viscosity upon contact with formation minerals driving acid exactly where it’s needed, even in the tightest or bypassed zones. Expect exceptional leak off control, lightning-fast viscosity response, and a perfectly clean, residue-free break in the presence of hydrocarbons.
Performance Highlight
Enhanced Viscosity Response for Superior Acid Diversion
DosVesta™ 201 delivers strong, temperature-activated viscosity development for reliable diversion into tight intervals, even in the presence of acid corrosion inhibitors. Comparative testing shows the DosVesta™ 201 system with ACI maintains ~25% lower viscosity than the baseline, confirming excellent compatibility with CorFix™ ACI-30.
Smart Non-Polymer Agents for Self-Diverting Acidizing
DosVesta™ 20 is engineered to temporarily reduce permeability in water-bearing intervals, directing acid into tight hydrocarbon zones by forming a structured network in non-hydrocarbon areas. This smart, polymer-free diverting agent does not affect acid viscosity at surface conditions or in mixing tanks, but increases viscosity as pH rises within the reservoir.
Self-Breaking Properties
A key engineered feature of DosVesta™ 201 is its ability to self-divert and self-break without the need for additional breakers or post-flush fluids, ensuring no residue remains in the reservoir.
Optimized for Acidizing Additives
Formulation of DosVesta™ 201 ensures seamless integration with standard treatment acidizing additives. It supports efficient fluid performance, enhances diversion control, and maintains stability under demanding reservoir conditions, delivering reliable results in matrix acidizing and stimulation operations.
