Water Based Sand Consolidations System

Non-Solvent Based Sand Consolidation System

Control of the undesirable sand production from weak sandstone formations or from proppant flow back after fracturing can increase productivity and reduce operating costs. Oil Chem's Aqua-Set is a nonsolvent-based sand consolidation system chemically binds the sand grains while maintaining sufficient permeability to achieve the production rate. It is a simple two components system that is designed to be injected into the reservoir to control the undesirable production of sand from weak sandstone formations, sand packs or fracturing sand flow back.

Oil Chem's Non-Solvent Based Sand Consolidation System contains two components - Aqua-Set A and Aqua-Set B. 2% KCl or other preferred fluid can be used as pre-flush to pre-treat the surface of proppant or sand grains, to enhance the consolidating of material onto the solid surfaces. Aqua-Set A and Aqua-Set B can be batch mixed or they can be added through a static inline mixer to form a homogeneous mixture before they are injected downhole. The setup time is approximate 16 - 24 hours at 60 °C - 90 °C. The post flush using 2% KCl is recommended immediately after the Aqua-Set injection.

Advantages

  • High flash point
  • Low viscosity, easy to pump
  • Economical. Simple applications using KCl pre-flush and post-flush
  • The Aqua-Set A and B can be batch mixed in the tank or can be mix in the injection line with an in-line mixer and pump into the wells
  • Curing time is from 12 to 24 hours at 60° - 90° C
