Integrated Model for Determining the Reservoir Rock Properties during Underground Storage of a Gas-hydrogen Mixture

Summary/Abstract: An integrated model for determining the reservoir properties of the rock reservoir during underground storage of a gas-hydrogen mixture is presented. The methodology consists of four main modules: Characterization of the core sample (mineral composition, porosity, and permeability), determination of the parameters of the gas-hydrogen mixture at different % hydrogen and methane contents (5%, 15%, 25%), study of flow properties (porosity and permeability of the core sample at different gas-hydrogen mixture contents), and a module summarizing the results. The results obtained from the study using the developed methodology form the basis for designing the storage indicators for gas-hydrogen mixtures in underground gas storage facilities.
