Study, Regulation and Effective Use of Groundwater in the Piedmont Plains of Azerbaijan

Abstract

The paper discusses the basics of methods for assessing groundwater in the foothill plains of Azerbaijan. When identifying groundwater reserves in mountainous areas, operational resources must be taken into account. In the process of exploration and exploitation of groundwater, it may be necessary to use exploration wells as exploration and observation wells, and vice versa. The transfer of wells from one category to another should be taken into account when planning geological exploration work. This can help improve the geological and economic efficiency of the work. The requirements for drilling and construction of hydrogeological wells of different categories are not the same. Methods for drilling hydrogeological wells are selected based on local geological and hydrogeological conditions, research objectives, design depths and diameters of wells and other factors. Reverse circulation drilling is used in conditions of deep groundwater (more than 3 m) and in continuous aquifers with a depth of 300 m or more and a diameter of 1000 mm or more. This method is used when it is necessary to drill exploration and production wells.
