Facies-Cyclic Analysis Based on GIS Data for Visean Terrigenous Sediments on the Example of the Permian Deposit

This paper is devoted to the application of facies analysis methods based on geophysical well logging (GIS) for Visean terrigenous sediments in one of the fields of Perm Krai. In the course of the study the data from 23 wells were analyzed, which made it possible to identify facies cycles and determine the spatial distribution of rocks. Based on the data obtained, a map of facies zoning was drawn up to optimize well drilling.
