Sediment-forming composition TAMOLEX®

Sediment forming composition TAMOLEX®

TU  2432-110-53501222-2015

Sediment forming composition TAMOLEX® is designed for water shut-off in production wells, for reducing the water-cut of produced fluid,  for injectivity profile leveling in injection wells, which leads to enhanced oil recovery and as a flow-diverter at acid stimulation in production wells.

Sediment forming composition TAMOLEX® is a dry mixture of compound organic soaps, well soluble in fresh water.


Application Area
  • Leveling of injectivity profile of injection wells with redistribution of filtration flow direction in injection wells with sandstone and carbonate reservoirs. 
  • Water influx protection in the production wells with flow rate not less than 1.5 tons a day.
  • Blocking of highly water-encroached interlayers in multipay pools.
  • Flow-diverting at acidizing  of production well with watercut of 80-90% and higher.

Customer Benefits

  • Selective performance in water-yielding interval of critical area.

  • Composition is stable within long period of time.
  • Wide range of application temperatures (over 100°C / 212°F).
  • Ability of working solution filterability into porous rock medium due to the low viscosity of the working solution (µ = 1.2 - 1.3 mPa⋅s). 
  • Controllable sediment forming.
  • No crystallization and freezing (vs fluids) at transportation, storage and application in winter.
  • Transportability and easy-to store, including the possibility to store the product at site near the well. 
  • No vessels are required for storage of the product/Easy incoming quality control.

Process Technique

Working solution of sediment forming composition TAMOLEX® is prepared in the vessels at site by diluting the chemical with fresh water with the temperature from  20 to 40°C  / 68-104°F.

The total amount of working solution of TAMOLEX® for each treatment is prepared in batches. The injection of TAMOLEX® fluid is done non-stop interchanged with the batches of mineralized water with the spacers of fresh water between the batches. The number of injection cycles and the consumption of TAMOLEX® depends on the geological and technical parameters of the treated and is determined individually for each object.  

For more detailed information about technique of application of TAMOLEX® contact the specialists of Sales & Service  Department of Polyex company.


Sediment forming composition TAMOLEX® is supplied in PP bags with PE liner or in big bags by 1 000 kg.
