| Summary: | Gashydrates are considered as near-future potential energy resources. Due to the lackof gas production data from gas hydrate reservoirs, numerical simulations arevery important to make production predictions for both experimental studies andfield production trials. Methane and water flow together when gas hydratesdissociate inside the sediments. Hence, many parameters of methane and watersuch as density, viscosity, enthalpy, internal energy and thermal conductivityshould be calculated at different pressure and temperature values duringnon-isothermal numerical gas production simulations from gas hydratereservoirs. As a solid phase, ice might exist in the pores due to theendothermic dissociation of gas hydrates. For this reason, water, methane, iceproperties as a function of temperature and pressure are estimated by the Matlabcodes written in this study: waterprop.m, gasprop.m, and iceprop.m. Density,viscosity, enthalpy, internal energy and thermal conductivity of water andmethane calculated with the Matlab codes in this study, National Institute ofStandards and Technology were compared, and the reliability of waterprop.m,gasprop.m and iceprop.m was proved. |
