| Study of gas hydrate formation possibilities in the upper part of the Predpatom trough (on example of the Kedergin gas condensate field) | |
| High prospects of the industrial gas content in the upper part of the Predpatom regional trough section are noted using Kedergin and Mukhtin fields as an example. A brief geological description of the section and tectonic position of Kedergin gas condensate field is given. The results of testing the Kelor productive unit confined to the Icher Formation of the Lower Cambrian are presented. Based on the gas component composition, the degree and type of stratum water mineralization, the equilibrium conditions of the hydrate formation for the Kelor productive unit are calculated. It is concluded that gas hydrates do not form in the upper part of the section of Kedergin gas condensate field due to high mineralization of the stratum water. It is suggested that weakly mineralized stratum waters in the upper part of the section may be concentrated in the folded wing of the Predpatom trough. The possibility of the gas hydrate formation in the zones of weakly mineralized stratum waters distribution in the upper part of the section is shown. Keywords: Kelor productive unit, reservoir water mineralization, hydrate formation conditions, Kedergin gas condensate field, Predpatom trough. |
