Sludge-forming reagent

Sludge-forming reagent “HimSGM” is designed for redirecting of filtration flows, with the view to enhance the workout of a reservoir, for water shutoff and the reduction of water cut in produced oil.


When the water solution of the reagent interacts with oilfield brine or with solution of calcium chloride, deposition of the sediment takes place, as a result of which, water inflow along the flooded-out and water-yielding intervals gets blocked.


  • It works in a wide range of temperatures up to 120°С;
  • Its filtration into porous medium due to low viscosity of the solution;
  • Selective working in water-cut formations;
  • Convenient transportation and storing of the product;
  • Stability and durability of the compound in terms of time;
  • The 4th class of hazard;
  • Convenience of the entry control for this product.

Recommendations to application

The solution of the sludge-forming reagent “HimSGM” is prepared on the surface, directly at a wellhead, or at a mud room. The technology consists of a two-flow consequent injection of the “HimSGM” solution and the solution of calcium chloride.

Recommended proportion of solutions is 2:1 correspondingly. More accurate concentration of the reagent is selected based on the conditions for its application and the technology applied during laboratory testing.
