Review of natural gas hydrates as an energy resource: Prospects and challenges ☆

Climate Change 1995 is a scientific assessment that was generated by more than 1 000 contributors from over 50 nations. It was jointly co-ordinated through two international agencies; the World Meteorological Organization and the United Nations Environment Programme. The assessment was completed by the Intergovernmental Panel on Climate Change (IPCC) with a primary aim of reviewing the current state of knowledge concerning the impacts of climate change on physical and ecological systems, human health, and socioeconomic factors. The second aim was to review the available information on the technical and economic feasibility of the potential mitigation and adaptation strategies.

Experimental investigation into methane hydrate production during three-dimensional thermal stimulation with five-spot well system

Due to the consumption of fossil fuels, an alternative energy source is necessary for the world’s continuous development. Methane hydrates, a vast energy resource that exists in deep-ocean or permafrost sediments containing approximately 10 000 Gt of carbon, are a potential energy source for the future. However, economically and safely producing methane from gas hydrate deposits is still not on the drawing board. The main reasons include (1) low methane production efficiency, (2) low methane production, (3) poor production sustainability. Thus, it is pressing to develop methane production technology and/or approaches to improve methane production efficiency. In this paper, we comprehensively review the research on methane production from gas hydrates, including the research on the characteristics of gas hydrate reservoirs, production methods, numerical simulations and field production tests. The different investigations are analyzed and relevant comments and suggestions are proposed accordingly.

Effect of horizontal and vertical well patterns on methane hydrate dissociation behaviors in pilot-scale hydrate simulator

Dissociation processes of methane hydrate in porous media using the depressurization method are investigated by a combination of experimental observations and numerical simulations. In situ methane hydrate is synthesized in the Pilot-Scale Hydrate Simulator (PHS), a three-dimensional (3D) 117.8-L pressure vessel. During the experiment, constant-pressure depressurization method is used during the hydrate dissociation. A vertical well at the axis of the PHS is used as the production well. The initial hydrate and aqueous saturations before dissociation are SH0 = 27% and SA0 = 37% in volume, respectively. The hydrate dissociates continuously under depressurization and there is little hydrate remaining in the PHS. The hydrate dissociation is an analog of a moving boundary ablation process, and the hydrate dissociation interface separates the hydrate dissociated zone containing only gas and water from the undissociated zone containing the hydrate. The temperature increases in the hydrate dissociated zone near t...
