Modifier for HCl acid МК-2

ТU 2122-003-12064382-98

Modifier for HCl MK-2 is designed for the application as an additive for HCl–based compositions to obtain acid stimulation fluid for production wells of KSPEO brand. MK-2 facilitates the prevention of stable high-viscose oil-acid emulsions formed during the process of acid stimulation of production wells in carbonate and sandstone reservoirs. It also helps to prevent precipitation of the products of the reaction between acid and rock.

Acidic modifier MK-2 is a mixture of surfactants and organic acid.  

Application Area for Acid Stimulation Fluids of KSPEO Brand Made  with MK-2

  • Acidizing of oil and gas production wells in carbonate and sandstone reservoirs with watercut up to 60%, especially when the production wells reduced the productivity due to precipitation and blockage of the critical area of formation with inorganic matters, and due to oil-water emulsions.
  • Fresh well completion after drilling operation, well switching into new production horizons, re-start of the well after conservation. 

 Appearance Semi-transparent liquid with the color varying from light-yellow to dark-yellow 
 Mass concentration of surfactant,
 % within the range 

Customer Benefits

  • No need to have tanks for storage of acid stimulation fluids of different grades and types in large quantities.
