This report deals with an investigation on the potential strata movements and subsidence associated with hydrate production. The investigation involved the determination of mechanical properties experimentally and numerical modeling of ground movements resulting from reservoir compaction. The objective was to investigate the influence of reservoir compaction on ground movements based the theories of continuum mechanics and principles of geomechanics. Here, the Finite Element Method was used in modeling the ground movements. This is a powerful computer-based technique which has been widely used in many areas of geomechanics. Parametric studies were performed to establish possible variation in the expected ground movements for different reservoir conditions and material characteristics. The results from this investigation can be useful in estimating the magnitude of ground movement problems associated with hydrate production from geological materials. 45 refs., 17 figs., 13 tabs.
