..., a thermodynamic model for gas hydrate equilibrium conditions and cage occupancies of N 2 + CH 4 and N 2 + CO 4 gas mixtures at different compositions is proposed. The van der Waals-Platteeuw thermodynamic theory coupled with the Peng-Robinson equation of state and Langmuir adsorption model are employed...

.... With comprehensive consideration of gas hydrate equilibrium conditions and borehole temperature and pressure field, we established method for prediction of gas-hydrate formation region in the shallow strata of deepwater drilling and method for prediction of gas-hydrate formation region when shallow drilling...

... supplied data involved changing either the air or water flow rate of a two-phase mixture from one equilibrium condition to another. Data was collected for both steady state and transient conditions, observations of flow pattern and measurements of liquid hold-up and sweep-out, pressure drop and slug...
