Process System Engineering of Gas Hydrate: Multiple Processes, Scales, Physics Fields and Senarios

Dear Colleagues,

The natural gas hydrate system has gained attention from across the world as a potential energy resource that has a high energy density and large resource volume. It also plays a role in climate change, as methane is a greenhouse gas, and may cause events like submarine slides or ocean acidification. More than 97% of the identified gas hydrate is located in marine environments. However, the scientific mechanisms and engineering control of gas hydrate nucleation, growth, and disassociation processes in the multi-media environment have not been fully understood; thus, this is the key scope of this Special Issue.

This Special Issue aims to introduce the most innovative studies covering physical, chemical, geological, geophysical, geomechanical, environmental, and economic aspects of gas hydrates and hydrate-bearing sediments. We welcome contributions of both reviews and original research papers.

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

• The modelling and prediction of dynamic processes of hydrate formation, accumulation, and decomposition based on numerical simulations, experiments, or field trials;
• Hydrate petro/rock physics studies for reservoir evaluation, such as hydrate saturation, permeability, etc.;
• The development of techniques for reservoir monitoring during gas production from hydrates;
• The energy recovery process from marine gas hydrates;
• Greenhouse gas sequestration and storage process by hydrate formation;
• Vertical methane leakage through the sediments and at the seabed;
• Gas hydrate accumulation and enrichment processes on different continental margins;
• Geological controls of high saturation gas hydrate and underneath FGZ;
• The dynamic shift of the gas hydrate system during a global warming event and related fluid migration and methane seepage processes at the seabed;
• Seabed methane seepage due to hydrate dissociation and related environmental effects;
• The gas hydrate flow process in long-distance oil–gas transportation pipelines.

We look forward to your participation in this Special Issue.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Processes is an international peer-reviewed open access monthly 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 2400 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.
