Diverting Agent

Diverting agents are specialized chemical additives used in acidizing treatments to temporarily block high-permeability zones and redirect acid flow to under-stimulated areas of the reservoir, ensuring uniform treatment coverage. UNPChemicals' VESMET series features advanced surfactant-based diverters, including zwitterionic surfactants for salt-tolerant viscosity development, tallow aminoamine oxide for robust foam stability, and ethoxylated ammonium quat for enhanced thermal resistance. These components work synergistically to create effective, self-degrading diversion barriers that optimize acid placement in both carbonate and sandstone formations, improving overall stimulation efficiency without requiring mechanical intervention.

Diverting agents are engineered chemical solutions that temporarily modify fluid flow paths during well treatments, ensuring balanced stimulation across heterogeneous formations. These smart additives create selective barriers in high-permeability zones, forcing treatment fluids into less accessible areas for improved reservoir contact. UNPChemicals' VESMET series utilizes a sophisticated blend of zwitterionic surfactants for adaptable viscosity control, tallow-based amines for durable foam structures, and ethoxylated quaternary compounds for temperature stability, delivering self-removing diversion that maximizes treatment effectiveness in complex carbonate and sandstone reservoirs.

What are Diverting agents?
Diverting agents are temporary flow control additives that improve stimulation coverage by selectively blocking already-treated zones and redirecting acids or other treatment fluids to under-stimulated reservoir sections, typically degrading after treatment to restore natural flow paths.

What are the main types of Diverting agents?
Primary diverters include viscous gels, foam systems, particulate materials, and surfactant-based viscoelastic fluids, with UNPChemicals' VESMET series specializing in advanced surfactant technologies that combine zwitterionic, amine oxide, and quaternary ammonium chemistries for superior diversion control.

Where are Diverting agents commonly applied?
These agents are critical in matrix acidizing of heterogeneous carbonate formations, acid fracturing treatments, and refracturing operations where uneven fluid distribution occurs, particularly in wells with severe permeability contrasts or long horizontal sections requiring zonal isolation.

How do you select the right Diverting agent?
Selection depends on reservoir temperature, permeability contrast, well geometry, and treatment type, with key considerations including diversion mechanism (viscous vs. physical blocking), cleanup characteristics, thermal stability, and compatibility with formation fluids and other treatment chemicals.

Why choose surfactant-based Diverting agents like VESMET?
Surfactant-based diverters like VESMET offer self-degrading, non-damaging diversion with precise viscosity control, excellent clean-up properties, and the ability to work in both carbonate and sandstone formations, outperforming particulate systems in complex well geometries while eliminating the need for post-treatment cleanup operations.
