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.
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.
