description: This work is devoted to the study of the pressure field in a bounded region with cracks and the development of an algorithm for calculating the field parameters. Tasks that were solved in the course of the study: 1. Creating an optimization model; 2. Development of an algorithm for minimizing the objective function of the optimization model; 3. Implementation of the algorithm in the form of program code; 4. Setting the limits of applicability; 5. Analysis of the stability of the solution depending on the input data. The work was carried out on basis of the Department of the Higher School of Theoretical Mechanics of Peter the Great St. Petersburg Polytechnic University in the framework of the direction "Development of tools for proxy modeling of reservoir pressure and reservoir conductivity". A method for numerical solution of the steadystate filtration problem in a confined reservoir was developed and implemented in the MATLAB software package for technical calculations. The reservoir contains a set of wells for which their pressures are defined. This is a combined numerical-analytical method in which the use of explicit formulas reduces the computational complexity of the numerical algorithm. As a result, the parameters of the bounded area field were analyzed. An algorithm for solving the problem in stationary and non-stationary formulation is developed and implemented in the MATLAB software package for technical calculations. A comparative analysis of the developed method with an exact solution for a bounded domain, in the form of an ellipse, was carried out.
