...+HYDRATE code (pT+H) to make the first field-scale assessment of a large, deep-ocean hydrate reservoir. Systems of up to 2.5M gridblocks, running on thousands of supercomputing nodes, are required to simulate such large systems at the highest level of detail. The simulations begin to reveal the challenges...

... refers to the removal of the sand from the failed region. In the model, a force balance is conducted between the frictional forces mechanically holding the sand in the formation and the hydrodynamic force (exerted by the flow) that induces detachment of the disaggregated sand. Gridblocks for which...

... that the limited memory Broyden-Fletcher-Goldfarb-Shanno (LBFGS) method 3 is relatively efficient for large history matching problems. Thus, in this study, the LBFGS method is used for history matching of both production and seismic impedance change data. Reservoir Characterization gridblock Upstream...
