Water Based Sand Consolidations System

Aqua-Set water-based Sand Consolidation system is a patented, environmentally friendly, economical, and easy-to-apply system. Aqua-Set is designed to be injected into the reservoir to control the undesirable production of sand from weak sandstone formations, remediation for sand packs, or prevent frac sand flow back after fracturing treatment. It chemically binds the sand grains and provides strength to the sand pack while maintaining sufficient permeability to achieve the production rate.

Advantages of the Aqua Set System

The new patented Aqua-Set Sand Consolidation system combines the advantages and the successful case histories of the resin/curing agent system, with many new added advantages and some
important differences:

• Aqua-Set is a water-based sand consolidation system. It also can be used in the hydraulic fracturing process during the last stage of the frac job to consolidate the frac sand and prevent sand production
  after the fracturing treatment
• High flash point, solvent-free
• Environmentally friendly and operationally safe
• Economical. Aqua-Set is a water-based emulsion consisting of 20 – 35% active ingredients and the balance is water. This makes the system extremely cost-effective.
• Versatile, the ratio of the Aqua-Set A, B and C can be adjusted depending on the formation/reservoir properties.
• Low injection viscosity and low injection pressure
• Lab data showed the product is generally set up within 24 hours at 90 °C, 2-3 days at 60 °C. However, due to different reservoir conditions, lab pre-test is recommended to ensure the curing of the Aqua-Set system
• Post flush is only required to flush the Aqua-set fluid out of the injection tubing and/or the coil tubing.
• Lab testing results showed the strength of the consolidated sand is 700 lb/in2 - 1,800 lb/in2 and the regained permeability is 75 – 98%
