In this study, a significant effect of fluid injection on the b-value and acoustic activity was found from the results of a laboratory study of the destruction processes caused by filtration processes. The migration of sources of acoustic emission from the side through which water was injected along the sample axis was detected. The difference in the rates of fluid diffusion into dry and saturated samples was confirmed. The used method of thermal stimulation of cracking allowed to increase the porosity and permeability of rock samples by almost an order of magnitude.
