Modifier for Acidic Composition MK-R

Technical Requirements TU 2122-041-53501222-2004

Purpose of Use

Modifier for acidic composition MK-R is designed to improve the effectiveness of acid stimulation of injection wells in carbonate and sandstone reservoirs in which produced waters with a high content of hydrocarbon inclusions is injected.

Modifier for acidic composition MK-R is used as an additive for  the HCl–based compounds.

МК-R  is a mixture of surfactants and oil hydrocarbon dissolvers.

Application Area of Acidizig Compounds of KSPEO-N brand modified with MK-R

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

More detailed information about the application of complex acidizing package KSPEO-2 grade N modified with MK-R can be seen on our site on the pages KSPEO-2 grade .

Customer Benefits

Complex nature of  impact of acidizing package KSPEO-2 grade N modified with MK-R provides a very efficient cleaning of  formation from hydrocarbon products and plugging precipitation brought into the formation with the injection of waste waters and formation waters.

Operation Technique and Consumption

In cases when production wells are converted into injective wells it is recommended to use KSPEO-2 grade N modified with MK-R composition as spacer before the injection of basic acidizing package KSPEO-2 grade N.  The consumption of MK-R for the spacer makes 30-40 %  of  total volume of basic compound.

 To select the optimal design of application, i.e. consumption and technique of application, it is recommended to contact the specialists of Service Department of Polyex company.

Modifier for acidic composition MK-R is certified for the application in oil-and-gas field.
