Annotation:
The authors of the article briefly overview modern approaches to assessing formations gas waters content in reservoirs of gas, gas condensate and oil fields and underground gas storage facilities (UGS).
Based on the analysis of the existing methods used for solving the problem, a method for identifying intervals of dissolved and dispersed gas content in reservoir formation waters, applying a set of geophysical and geological-technological research methods, which has not been previously used in the Russian Federation, is proposed. Assessment of gas content using the proposed method will provide information on the dispersed gases distribution over the area and reservoir beds of fields and UGS. The method should become the information basis for regulatory documents related to various directions of the oil and gas industry: assessment of the resource base and development of hydrocarbon fields, creation and operation of UGS.
