Abstract: Secondary transformations of carbonate rocks of the Late Cambrian age of the Nepa-Botuoba anteclise significantly change the filtration-capacitive properties that can lead to both improvement and deterioration of the reservoir characteristics of these rocks. An extensive petrophysical collection of samples was analyzed to study the development of secondary processes, including salinization of pore space with halite. Examples of the effect of the complex multicomponent rock composition and secondary processes on the elastic properties of rocks. These were determined from the data of an extended set of logging and wave acoustic logging methods are shown
