Paper Title
Application of Mathematical Statistics in Drilling

The article is devoted to questions to determine the values of hydraulic fracturing. There are several ways to determine the value of the hydrofracturing pressure. We have given specific recommendations of their choice. In connection with this there are mentioned results on the application of mathematical statistics in the article to determine the hydraulic fracturing pressure in drilling. Keywords- Hydraulic fracturing, drilling, density of drilling fluid, rotor, the hydrodynamic pressure.
