Hydrogeological researches on mineral deposits are conducted at various stages of prospecting process. Hydrogeological division into districts has to be the cornerstone of all hydrogeological researches. At weak study of the territory it has to be based on the all-geological orogidrografichesky data. Hydrogeological researches on mineral deposits at each stage and a stage of prospecting process include various complex of methods and are characterized by the tasks. The data obtained as a result of hydrogeological researches, then are systematized and presented in the form of various cards, schedules, tables and schemes. Standard hydrogeological cuts, cards of water oil and gas-water contact, гидроизопьез, isobars, temperatures, hydrochemical cards, cards of the chemical composition of waters are the most important. By results of further hydrogeological researches hydrodynamic, hydrogas-chemical, termobarichesky characteristics of productive thickness (layers) of fields are specified that allows to reveal regularities of change separate of the specified parameters. Data of hydrogeological researches are important at design of development of mineral deposits, and also for conducting monitoring of process of development.
