Sand Consolidation Fluids

Prevent screen and completion damage

Conglomeration
Strengthens the attraction between particles without damaging formation permeability.
Consolidation
Chemically binds the grains of sand that make up the formation matrix while ensuring sufficient permeability to achieve viable production rates.

SandAid sand conglomeration technology

SandAid technology is a patented chemical solution that significantly improves sand management and enhances production. The chemical process increases the attraction between particles without imposing damage by trapping formation sand and fines to maximize sand-free flow rates and increase production.

Nanoglue low-viscosity sand consolidation bond

Nanoglue bond prevents the migration of loose sands and fines from a formation into a wellbore. Unlike traditional sand consolidation treatments, which can greatly reduce the original permeability of the formation, Nanoglue bond is characterized by low viscosity that decreases downhole friction, enabling faster injection rates.
