With a view to reducing the calculation errors in prediction and validation of an extraction ratio, the authors reviewed the analytical research and lab-scale test data on simulation of mineral mining in the presence of carbon dioxide and with regard to the geology and geophysics of a deposit. The subject of research is the reservoirs containing hydrocarbon and non-hydrocarbon components. Namely, the stacked multicomponent systems of Chayanda reservoir are examined. The review of the analytical and testing data aimed toward hydrodynamic modeling made it possible to project an operational mining scheme using feasible mining methods. The research was complicated by the difficulty of obtaining reliable information on thermodynamics and phase transitions in the course of mining. Interpretation of the reviewed lab-scale studies confirmed that the data on the reserve extraction were different in every experiment but had close values to the predictive estimates and field evidence. One of the major factors to affect the research results is the unbalance of the thermodynamic equilibrium in a system. The laboratory investigations pointed at the nonuniform effect exerted by the geological conditions on the extraction ratio. Furthermore, the influence of the carbon dioxide content of the system showed up as the decrease in the production output. Alongside with the agreement between the limit saturation of the study reservoirs and the predictive estimate from the thermodynamic calculation, the lab-scale testing exhibited a trend of improved and probably complete mutual dissipation of gas–steam carbon dioxide system.
