Three-Dimensional Digital Modeling in the Rehabilitation of Hydrocarbon-Contaminated Geo-Environment as the Basis for Managing Man-Made Systems

The paper considers the modeling of open, multi-component and non-stationary natural and man-made system represented by geo-environment, oil lens and structures. This system is open and evaluated by a wide range of parameters. Reliable information on the current state and relationships of all main elements is needed to manage such complex systems. The information on the genesis, dynamics of parameters allows one not only to assess the state of the system, but also help predict its changes in space and time. Therefore, recommendations are given for the study, assessment of the state and migration of accumulated hydrocarbons in the geological environment using the methods of numerical and digital modeling. Currently, modeling is used for oil production enterprises in assessing the reservoir capacity and flow rate at natural hydrocarbon deposits. It should be noted that the considered system differs significantly from natural deposits of oil. Therefore, the authors introduce parametric adjustments to the description of the natural and man-made system. In addition, the man-made lens makes a negative impact on the environment. It sets the task of not only tracking the behavior of the lens in the geo-environment and using the accumulated hydrocarbon resources, but also the cleaning of rocks after the recovering of the useful product. A physical-chemical method of purification of geological environment from the pollutants of oil origin with the use of surfactants was proposed to reduce man-induced load exerted by the lens hydrocarbons. The selection of conditions for injection of reagents into the geo-environment, the parameters of their migration, the locations of injection wells was also determined by the solution of the problem of modeling the system of elements in the geo-environment, oil lenses and structures. This method makes it possible to predict the system behavior and to develop a plan of measures for its liquidation.
