Numerical Analysis for Fault Reactivation during Gas Hydrate Production

Fluid-Solid Coupling Numerical Simulation on Natural Gas Production from Hydrate Reservoirs by Depressurization

Measurement of Mass Transfer Coefficients of Natural Gas Mixture during Gas Hydrate Formation

In this study, mass transfer coefficients (MTC’s) of natural gas components during hydrate formation are reported. This work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. Several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...

Driving Force for Nucleation of Multi-Component Gas Hydrate

Based on driving force for crystallization of one-component gas hydrate, in this report an expression for the supersaturation for crystallization of multicomponent gas hydrate is derived. Expressions for the supersaturation are obtained in isothermal and isobaric regimes. The results obtained are applied to the crystallization of hydrates of mixtures of methane plus ethane and can apply to ...

Stress field changes and faulting regimes analysis for determining fault reactivation possibility in cap rock and reservoir due to production & pressurized in Aghajari Oil Field - Iran̓s South West

Production and injection of fluid may cause hydraulic fracture, shear fracture at crack levels, or re-activation of faults and existing discontinuities by reducing effective stress by changing the pore pressure and corresponding changes in the stress field. Therefore, the deformation of the earth, seismic occurred, the reactivation of discontinuities and the impermeability capacity of the rocks...

Evaluation of the Gas Production Potential of Challenging Hydrate Deposits

We use the TOUGH+HYDRATE code to assess the production potential of challenging hydrate deposits, i.e., deposits that are characterized by any combination of the following factors: absence of confining boundaries, high thermodynamic stability, low temperatures, low formation permeability. Using high-resolution grids, we show that a new horizontal well design using thermal stimulation coupled wi...
