Abstract
The aim of the study was to test the method of electro-facies analysis for mapping reef structures in the conditions of the junction of the Vilyui syneclise and Aldan anteclise. The article presents the results of a study of geoelectric characteristics using the method of electro-facies analysis. The confinement of buried bioherms to fault zones has been established. Facies zones corresponding to paleographic representations of the development of the region were identified. A map of the distribution of electrofacies for the Cambrian section interval was constructed, with boundaries of the distribution of reef deposits in the aisles of the study area. A typical geoelectric section showing the geoelectric properties of a section of the West Yakut barrier reef is given.
Separation of facies based on electrical exploration data is able to provide operational information on the boundaries of the studied area. With insufficient drilling data, electro-facies analysis can speed up the interpretation of electrical exploration data.
