Prospects of applying formation water and heavy brines derived therefrom in oil production and national economy

Abstract

In recent years, the amount of minerals recovered from the earth interior exceeds their production over the entire past human history. The reserves of some rare elements have been significantly reduced and the demand for them has increased dramatically through the use of new techniques and technologies. The task of developing new types of mineral raw materials from formation waters has become ever more relevant. In the process of formation water preparation during the production of table salt the fluids and heavy brines are obtained, which are suitable for their further use in oil production. The fluid obtained through deferrization of formation water has reduced content of magnesium ions. The use of this fluid makes it possible to increase the mechanical strength of the cement stone, the tightness of the “column-cement stone” contact zone, and to reduce magnesia corrosion.
