Abstract

The purpose of this study is to investigate the effects of the geomechanical mechanisms on the gas production of a depressurized Class-3 hydrate deposit, Four-Way-Closure Ridge. From this case study, we found that there is a lower gas production rate and a longer production plateau when geomechanics are considered in the fluid flow modeling. The Young's modulus and Poisson's ratio are sensitive parameters to the reservoir deformation and the seafloor subsidence. We suggest that the geomechanical issue should be well considered in a hydrate deposit development project.
