Marine Gas Hydrates: Formation, Storage, Exploration and Exploitation

Dear Colleagues,

Natural gas hydrates, as a significant reserve of clean energy, have been extensively investigated by energy institutions and researchers all over the world. Pilot production has already begun in China, Japan, Canada and the United States. The results show that the exploitation of gas hydrate resources is technically feasible. However, the production of natural gas has not yet reached the threshold of commercial exploitation, and the safety of long-term production has not been verified; hence, efficient extraction technology and methods are urgently needed for the development of natural gas hydrates. In terms of drilling, the weak bonding characteristics of the hydrate layer remains a significant challenge. In addition, hydrate flow assurance in the process of gas hydrate transport and storage has hindered the development of oil and gas fields. Therefore, research and development of new hydrate management methods and technologies are now a priority in the field of energy.

This Special Issue aims to collate papers that underscore the latest progress in theory, experiment, modeling and application of marine gas hydrates, as well as highlight the processes of their formation, storage, exploration, exploitation, and transportation.

Topics of interest include, but are not limited to, the following:

• NGH formation;
• NGH storage;
• NGH drilling;
• NGH exploration;
• NGH well completion;
• NGH extraction simulation;
• NGH management in flow assurance;
• Novel technologies base on NGH;
• CCS related to NGH;
• Fundamentals of NGH.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
