Annotation:

The relevance of studying the impact on the reservoir bottom zone (RBZ) is caused by the necessity of improving the efficiency of oil production wells operation while ensuring environmental safety. The authors of the article analyzed the methods of exposure on RBZ emphasizing optimal chemical reagents selection that ensure the safety of technological operations and minimize environmental aftereffects. The importance of an integrated approach that includes evaluation of the effectiveness, safety and environmental sustainability of the applied technologies is noted. Special attention is paid to the correct selection of reagents with minimized environmental risks, strict compliance with their use and storage instructions, personnel training and technical state of equipment as well as compliance with hygiene standards on the content of harmful substances in the environment. It is noted that implementation of these measures contributes to the optimization of oil production, increase well productivity and reduce negative environmental impact, which is an important condition for the sustainable development of the oil and gas industry.
