After this specific amount of bottom water in gas field is calculated by formulas provided that condensation water under stratal conditions exists in the form of vapor. Later specific amount of condensation water in gas field is established. Thereupon total amount of bottom water and total amount of condensation water per day are determined. On basis of obtained data total amount of water in gas field per day is computed. So average specific amount of bottom and condensation water in gas field can be timely determined on basis of data of chemical analysis of water samples selected from inlet separators for general mineralization as well as total amount of water in gas field per day.
