Theoretical and practical problems of digitalization of oil and gas complex enterprises

The problem of ensuring the guaranteed normal functioning of digital systems in the Russian oil and gas industry in the context of the sanctions war of the United States and the European Union against this industry is discussed. To solve it, it is proposed to use hardware and software with built-in intelligent self-monitoring and self-correction mechanisms. It is proposed to counter bans on the supply of supercomputers for hydrodynamic calculations by using computational methods based on exact solutions and coarse grids.
