Application Scenarios

Designed for oilfield stimulation treatments including matrix acidizing and acid fracturing.

Suitable for improving formation permeability by enhancing acid placement, reaction control, diversion and fracture etching performance.

Solutions

Acidizing restores or improves permeability by dissolving rock cement and blockages in formation pores and fractures. Proper acid-fluid rheology and diversion help extend acid action distance and improve stimulation efficiency.

• Increase acid-fluid viscosity when required.

• Reduce active-acid diffusion and delay acid-rock reaction.

• Extend acid action distance in the formation.

• Improve fluid-loss control and fracture etching.

• Support matrix acidizing and acid-fracturing treatments.

• Provide options for high-temperature and special logistics conditions.
