Abstract
In order to increase the efficiency of microbiological methods of influencing the formation and use them in formations having conditions, which are unfavorable for microorganism activities, a new microbiological method of oil recovery increase was developed in which a rim of low-saline flush fluid was used prior to the injection of organic substrate. As an organic substrate, a composition of two types of milk whey was used. In this case, an oil recovery factor of 74% was obtained. The developed method provides a means for effectively dealing with issues of non-waste technologies creation, and for the improvement of the ecological situation at developed deposits.
