Summary

A-
A+
The results of research about influence of hard and alkaline waters and their compositions of different ratios onto oil displacement from a reservoir are presented in the article. They show the recovery factor to be high. It has been possible to increase recovery factor to 0.8 – 0.9 by adding hydrocarbon reagent and electrolyte “M” to the utilized liquid mixture. This is a significant value when developing oil fields with enormous amounts of residual oil.
