In modern carbonate reservoir stimulation, VES (Viscoelastic Surfactant) diverting acid systems have become one of the most effective technologies for improving acid placement and maximizing reservoir contact. However, many field applications focus primarily on selecting a suitable VES diverting agent, while overlooking another equally critical component—the acidizing corrosion inhibitor.

In reality, the overall performance of a VES diverting acid system depends not only on the diverting efficiency of the surfactant but also on the corrosion protection provided throughout the acid treatment. A carefully matched corrosion inhibitor package can significantly improve operational safety, equipment protection, and treatment reliability under high-temperature acidizing conditions.

At Sichuan All-Chem Chemical Co., Ltd., we have developed complete VES diverting acid solutions that combine our AC-VES Viscoelastic Surfactant Diverting Agent with high-performance Acidizing Corrosion Inhibitor products for various acid systems and temperature ranges.


Why Corrosion Control Matters in VES Diverting Acid Systems

VES diverting acids are typically formulated with hydrochloric acid (HCl) or blended acid systems for stimulating carbonate reservoirs. These acids provide excellent dissolving capability but also create severe corrosion risks for tubing, coiled tubing, pumps, valves, and other downhole equipment.

Without an effective corrosion inhibitor, operators may encounter:

  • Severe corrosion of steel tubulars
  • Reduced equipment service life
  • Increased operational risks
  • Higher maintenance and replacement costs
  • Difficulty extending treatment time at elevated temperatures

As treatment temperatures continue to increase, corrosion protection becomes just as important as diversion efficiency.


Integrated Solution: VES Diverting Agent + Acidizing Corrosion Inhibitor

Unlike conventional chemical suppliers that only provide a diverting agent, Sichuan All-Chem offers a complete stimulation package consisting of:

AC-VES Viscoelastic Surfactant Diverting Agent

Our AC-VES provides:

  • Excellent temporary diversion capability
  • High compatibility with hydrochloric acid systems
  • Efficient wormlike micelle formation
  • Self-breaking after contact with formation hydrocarbons
  • Low formation damage
  • Easy surface mixing without polymer residue

Matching Acidizing Corrosion Inhibitor

The success of any VES diverting acid treatment largely depends on selecting the appropriate corrosion inhibitor.

Our Acidizing Corrosion Inhibitor offers:

  • Outstanding corrosion protection in HCl acid systems
  • Excellent compatibility with VES formulations
  • Stable performance under high-temperature conditions
  • Low dosage requirement
  • Reduced total treatment cost
  • Excellent dispersibility in acid solutions

Unlike many traditional corrosion inhibitors that negatively affect VES viscosity, our formulation has been optimized for compatibility with viscoelastic surfactant systems, helping maintain both diversion performance and corrosion protection simultaneously.

Optimized Compatibility Between VES and Corrosion Inhibitor

One common challenge in acidizing operations is incompatibility between corrosion inhibitors and surfactants.

Poor compatibility may result in:

  • Reduced VES viscosity
  • Phase separation
  • Lower diversion efficiency
  • Premature viscosity loss
  • Inconsistent field performance

Our R&D team continuously evaluates compatibility between our VES diverting agent and corrosion inhibitor formulations to ensure stable acid systems across different acid concentrations and operating temperatures.

This integrated design allows customers to simplify formulation development while improving treatment consistency.


Suitable for Multiple Acidizing Applications

The combined AC-VES and Acidizing Corrosion Inhibitor package is suitable for:

  • Matrix acidizing
  • Acid diversion treatments
  • Carbonate stimulation
  • Coiled tubing acidizing
  • High-temperature acidizing
  • Multi-stage acid stimulation
  • Production enhancement of carbonate reservoirs

The system can be customized according to:

  • Acid concentration
  • Bottom-hole temperature
  • Treatment duration
  • Formation mineralogy
  • Operational requirements

Supporting High-Temperature Acidizing Operations

As reservoirs become deeper, higher temperatures require more advanced corrosion protection.

Our acidizing corrosion inhibitor technology has been developed for multiple temperature grades, allowing customers to select the most suitable formulation according to their operating conditions.

Typical applications include:

  • Medium-temperature acidizing
  • High-temperature acidizing
  • Ultra-high-temperature acidizing
  • Long-duration acid treatments

This flexibility allows operators to achieve excellent corrosion protection without sacrificing the rheological performance of the VES diverting acid.


One Supplier for the Entire Acidizing Chemical Package

Instead of sourcing chemicals from multiple vendors, operators can simplify procurement by obtaining both the diverting agent and corrosion inhibitor from a single supplier.

Benefits include:

  • Proven product compatibility
  • Simplified laboratory evaluation
  • Faster field implementation
  • Reduced formulation development time
  • Lower overall operating cost
  • Reliable technical support
