Modifier for acidizing fluid for injection wells МК-N

TU 2122-026-53501222-2002

Acid modifier MK-N is designed for the application as an additive for HCl–based solutions to obtain acidizing fluids KSPEO-2NKSPEO-3 TN, KSPEO-4 N for injection wells. Modifier MK-N is used in acidizing fluids for injection wells in carbonate and sandstone reservoirs to prevent precipitation of the products of the reaction between acid and rock.

Acid modifier MK-N is a mixture of surfactants and organic acid.

Application Area For Acidizing Fluids of KSPEO-N Brand  made with Modifier MK-N 

  • Improving the injectivity in injection wells in carbonate and sandstone reservoirs, especially when the injectivity was affected by formation plugging with rust precipitation, suspended solids in injected water, precipitation formed as a result of incompatibility of salts in injection water and in formation waters, as well as by the products of vital activity of bacteria.
  • Fresh injection well completion after drilling operations and re-start of the wells after conservation.
  • Conversion of production wells into injection wells.
