Abstract
We present the experimental results of true triaxial independent loading test bench studies of the influence of a triaxial stress state with unequal components on the filtration properties of rock in oil and gas gathering mains. We show that the permeability of rock subjected to stresses can irreversibly decrease or increase. The discovered effects are of great importance when designing optimal oil and gas well drilling and operation regimes.
