A comprehensive assessment of the fracturing and blockiness of the gabbro of the Pshenychne deposit
In order to ensure the correct development of the deposit and to use the effective technologies for stone extraction, it is necessary to carry out a comprehensive assessment of the structural properties of the massif, in particular, to perform a study of

The Model for Calculating Pore Evaluation of Fractal Rock Body Under Hydraulic Fracturing [PDF]
In general, the pore medium of rock has fractal characters. In order to calculate the change regulations of porosity and evaluation character of the rock under hydraulic fracturing accurately, in this paper, a new damage variable was defined to describe ...

Geomechanics of Unconventional Reservoirs: Hydraulic Fracturing and Nanoindentation [PDF]
Geomechanics is the study of the mechanical response of geologic formations subjected to injection, production, and storage of fluids in the subsurface. It plays a role in understanding formation integrity and the response to oil and gas depletion during
