Surface-active agents (SAA)

Surface-active agents of «Unicor-10» series are aimed to solve a whole number of reservoir engineering problems and uniform drainage of oil and gas accumulations. The reagents don’t  effect on corrosion wear of downhole equipment and plant equipment.

They allow to delete the fluid accumulated on the hole bottom which can be both organic origin and highly mineralized stratal water. Reagents of this series contribute to well bore refinement of redundant fluid, stabilize the performance of oil and gas processing facilities  and improve fluid influx from oil pool to bottom hole.

Principal characteristics of the reagents series «Unicor-10»

Physical form                                   

1) liquid from light yellow to dark brown colour

2) solid SAS soap sticks

Density at 20 ° C, kg / m³, within 0,790 – 0,820
Solidification temperature, ⁰C, not exceeding -30
Effective dosage, g per 1000 m³ 1-10

 

            Effective dosage of «Unicor-9» series depends on  percentage of water production, mineralization and sediment content. SAA product range comprises liquid forms which solution may be delivered without production shutdown and solid forms which may be applicable on a fields with lack of special-purpose machines or at final stage field development.

            SAA of «Unicor-10» series are multifunctional in terms of principle of operation. They act depending on type of dissociation of water-oil and gas system and completely meet with oil&gas industry requirements:

  • Nonionic SAA that prevent fluid accumulation by forming adsorption layer of unoriented molecules on the surface of the fluid molecules. Applicable for neutral ambient with pH=7;
  • Anionic SAA that prevent fluid accumulation by forming adsorption layer of cation oriented molecules on the surface of the fluid molecules. Applicable for acid and corrosion mediums with pH≤7;
  • Amphoteric SAA, universal products that prevent fluid accumulation on the bottom of a well by showing acidity and alkalinity of dissociation. Applicable for any mediums, pH=1 – 14.

Due to its multifunctionality and high efficiency  with low dosage and cost, SAA of «Unicor-10» series are one of the most reasonable and affordable solution of a problem of  wellbore fluid  withdrawal.
