Abstract
Summary
In this paper, we compare the fracture opening pressure in the laboratory experiment and in the theory. The opening pressure knowledge is necessary not only for hydraulic fracturing, but also to estimate the stability of the wellbore. In addition, this value determines the possible formation of small fractures in the rock, where the pore pressure exceeds the fracture opening pressure. Also, the knowledge of this value is necessary for calculating the maximum horizontal stress, the finding of which is a nontrivial task. Our study showed that the experimental value of the fracture opening pressure differs from the theoretical one by several times.
