The article presents a three-dimensional mathematical model of the gas filtration process in porous media and a numerical algorithm for solving the initial-boundary value problem. The developed model is described using the nonlinear differential equation in partial derivatives with the appropriate initial and boundary conditions. The proposed mathematical apparatus makes it possible to carry out hydrodynamic calculations taking into account changes in the main factors affecting the process under consideration: permeability, porosity, and thickness of layers, gas recovery coefficient, visc
The article deals with the existing system of gas pipelines between hydrocarbon production facilities at the Yuliivskyi oil and gas condensate production facility (YOGCPF). This system of gas pipelines ensures the flow of hydrocarbon raw materials from the wells of Narizhnianske, Yuliivske and Skvortsivske oil and gas condensate fields to the complex gas treatment unit (CGTU). The preliminary treatment of natural gas from mechanical impurities, liquid, hydrocarbon condensate and water is carried out at gas preparation plants of these fields.
