The Volga?Ural petroliferous basin is the oldest oil producing region of Russia. Therefore, most of the major oil and gas fields of traditional types here are already at the final stage of production. This provides for the increasing interest to develop unconventional resources of hydrocarbons associated with potential resources of the Upper Devonian?Lower Carboniferous (Tournaisian) Domanik-type sedimentary formations. This study focused on the geomechanical and petrophysical evaluation of the Domanik Formation a...

Determination of the present-day stress field tensor is one of the fundamental problems of modern geodynamics. Nowadays, world stress map (WSM) project provide a global compilation of information on the crustal present-day stress field. From a practical point of view, knowledge of the stress field allows us to solve a number of production problems related to the investigation and extraction of hydrocarbons in safety way. In particular, orientation of the main stresses and stress regime are necessary to set the bou...
