The lithologic structural characteristics of carbonate rocks of Famennian-Tournaisian oil fields, southern Perm Prikamye

The article presents the study of distribution of the lithological characteristics of carbonate rock of the oil deposits of the southern part of Perm Prikamye. The study revealed that Tournaisian deposits are predominantly composed of the nodular algal limestone. Predominantly algal limestone has the highest permeability and porosity, but predominantly nodular limestone is characterized by lower reservoir properties. Recommendation for usage of results of study for geological and geodynamic modelling of oil reservoirs is given.
