This article is a tentative experimental study on hydrocarbon migration and accumulation in the carbonate reservoir, which is a complex media that includes a pore system and fracture system.
An anomalously strong seismoelectric effect of the first kind (a vibration-induced change in the electrical resistance) is discovered for carbonate reservoir rocks of the Zavolzh'e region.
In the course of transformations in the carbonate reservoir, the juvenile fluid flow became undersaturated with respect to silica, which was a necessary prerequisite for the formation of corundum.
Diapirism is typical of both foredeeps: deformation of salts in the Persian Gulf area; deformation of clays and, possibly, salts in the Terek Depression; and presence of the principal oil pools in fractured and porous-fractured carbonate reservoirs.
