Methods for Purification of Aquifers of Oil and Gas Fields and Separation of Valuable Components From Their Composition
Abstract
The article is devoted to the analysis of methods for purifying produced water from oil and gas fields and separating valuable components from its composition. The essence of the issue is connected with the fact that the problem is multifaceted and has a complex nature. Along with the production of hydrocarbons from oil and gas fields, the raising of produced water to the surface of the earth causes serious technological, ecological and economic problems.
In general, in addition to the utilization of produced water, issues such as purifying these waters from polluting components and re-injecting them into the formation to maintain the formation pressure, separating valuable metals and substances in their composition, protecting the ecological environment, and making them suitable for irrigation systems are relevant.
Produced water extracted from hydrocarbon fields to the surface of the earth can cause serious environmental problems, since these waters contain a large amount of mineral substances, salts, heavy metals and organic pollutants. Improving produced water purification technologies is of great importance both for environmental protection and for improving water quality for reuse.
The research studies the efficiency and application possibilities of various technologies, including mechanical, chemical, biological and membrane-based methods. The application of innovative methods in the process of produced water treatment, in particular, new approaches such as nanomaterials and advanced oxidation technologies, are promising for minimizing waste and efficient use of resources.
