Reagent Description

The reagent is designed for oil flow stimulation from productive strata of oil wells and increasing intake capacity of injection wells by improving the filtration properties of oil-containing rocks.

Upon interaction with RMD-K with carbonates, no insoluble secondary reaction products are formed. RMD-K has both inhibitory and anti-corrosion properties.

It is used in wells with reduced filtration characteristics of bottom-hole formation zone. Water cutting of well production should not exceed 12%, formation pressure should be at least 50% of the initial value.

Answers to Questions

How long is the RMD-K effect during well bottom-hole treatment in polymictic collectors?

The effect lasts over 12 months, so it is several times more efficient than similar hydrochloric treatments.
