Review of gas hydrate dissociation kinetic models for energy recovery

摘要

In this work, a comprehensive review of gas hydrate dissociation kinetic models and hydrate reservoir simulators are provided. The main features of the dissociation kinetic models are summarized, with model formulation, assumptions, governing equations, solution method and limitations highlighted. A clear relationship between different kinetic models is identified according to the driving mechanisms and the progression of each hydrate dissociation kinetic model is presented to capture major improvements. Besides, key intrinsic kinetic parameters used in the kinetic models are extracted, which could be applied directly in future hydrate dissociation modelling study. Various aspects of hydrate reservoir simulator, including its theoretical basis, computational algorithms and applications have also been reviewed to provide a holistic view on the development of reservoir simulation for energy recovery from natural gas hydrates. Finally, further developments are suggested for improving the hydrate dissociation models relevant to practical applications of clathrate hydrates. (C) 2016 Elsevier B.V. All rights reserved.
